Software Product Description ________________________________________________________________ PRODUCT NAME: DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 DESCRIPTION The DECserver 200 Terminal Server is a network terminal switch for Ethernet Local Area Networks. The DECserver 200 provides a convenient method to logically connect up to eight Digital asynchronous terminals to one or more service nodes (hosts) on an Ethernet. Once the terminal is connected, a user can utilize application programs and utilities as though the terminal were directly connected to a host via a DZ11, DMF32, or DHU11 device, with a few exceptions. Thus, it may be possible to utilize the DECserver 200 to connect all terminals to service nodes in place of traditional interfaces, except for host console terminals. Remote connection via dial-in modems is fully supported. The DECserver 200 also provides the capability to connect host systems that do not support the LAT protocol, Digital personal computers, and dial-out modems directly to ports on the server. Interactive server users can issue commands to connect to ser- vices which are offered on such ports. Port-to-port connections on the same server are also supported. The DECserver 200 implements the Local Area Transport (LAT) pro- tocol for communication with service nodes that implement this protocol on the same Ethernet. This interface has been optimized for high terminal I/O performance over an Ethernet, while reduc- ing host CPU cycles required to handle interrupts. Hence, under most I/O loading conditions, a significant performance gain may be realized by using the DECserver 200 versus direct terminal connections via DZ11s. DIGITAL March 1991 AE-JC43D-TC DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 The DECserver 200 also implements and supports the Terminal De- vice/Session Management Protocol (TD/SMP) to manage multiple sessions at the device level. The DECserver 200 provides the ability to communicate with devices which also implement this protocol, and assist in the management of multiple sessions for these devices. By implementing this protocol, the DECserver 200 can permit attached devices to maintain screen and keyboard con- text for multiple LAT sessions, as well as allow these devices to run multiple LAT sessions concurrently. Software that runs on the DECserver 200 is downline loaded over the network from a Phase IV DECnet load host. Terminal access using the DECserver 200 on RSX-11M-PLUS and Micro/RSX nodes requires that DECnet is running on all RSX service nodes. Support for the LAT protocol is provided as a part of DECnet- 11M-PLUS and DECnet-Micro/RSX. RSX-11M is not supported as a LAT service node or load host. However, RSX-11M and RSX-11S systems can be accessed from a LAT network by connecting them, via EIA-RS-232C cables, to remote access ports on the DECserver 200, and specifying a service name for terminal users to access these ports. For wide area network communications, terminal users can con- nect to a local service node running DECnet, where they can "SET HOST" to a remote system via the DECnet network terminal protocol. If this system has the requisite X.25 or SNA 3270 ac- cess routines, a terminal user could communicate to a remote SNA or X.25 host through the appropriate gateway and this inter- vening host. A DECserver 200 terminal user cannot communicate directly to remote hosts through DECnet Routers or X.25/SNA Gateways. Wide area network traffic will not provide the same high level of performance as local terminal connections, due to the additional DECnet and internet protocol overhead. DECserver 200 Options 2 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 There are two options of DECserver 200 hardware: o The DECserver 200/MC, containing RS-232-C lines with full modem control o The DECserver 200/DL, containing DECconnect lines with data leads only The DECserver 200 server software is configured to operate on either option. However, all features pertaining to modem con- trol, modem support and modem-signal flow control, apply to the DECserver 200/MC hardware only. In addition, it is strongly rec- ommended that the DECserver 200/MC option be used when directly connecting non-LAT host systems to the server. The DECserver 200/DL may be used when connecting most terminals and printers to the server. Features Terminal Connection Management Through the use of a simple command, users can establish a logical connection, called a session, to any service node that implements the LAT protocol on the same Ethernet LAN. This connection makes the terminal appear as if it were physically connected to the service node, and the terminal user can use standard system utilities and applications supported by that node. Each terminal connected to the server can connect to the same or a different service node on the Ethernet. Furthermore, several servers can be used to connect many terminals to one or more service nodes. A service node can have one or more services that are offered to DECserver 200 users. Services and nodes are identified by name. Users always connect to services, not to nodes, although often one of the service names will be the node name. Non-LAT Host Support 3 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 The DECserver 200 can be used to provide logical terminal con- nections to hosts that do not implement the LAT protocol. In this type of configuration, the server becomes the Ethernet connection and protocol support for these hosts. This expands the LAT network accessibility to the terminal user to include LAT hosts directly connected to the same Ethernet and hosts connected to the LAT network via the DECserver 200. A host that supports XON/XOFF, ASCII standards and EIA RS-232- C/CCITT V.24/V.28 interfaces can be connected to the DECserver 200. This provides the terminal user with a transparent connec- tion to the non-LAT host. It is strongly recommended that server port and the host side port utilize modem control signals to automatically signal the host upon session disconnection. In this configuration, there is a one-to-one correspondence between the port on a DECserver 200 and the connection on the host. The server manager assigns service names to individual ports or groups of ports that connect the host interface to the server. Load Balancing When a connection is made to a service, the actual node for the connection is determined by load balancing. Load balancing is a process the server uses when more than one node offers the same service. Service nodes with the same names may be running different operating systems. Using the load balancing process, the server connects to the node with the highest rating for the service desired. This rating is based on the current loading on the nodes that offer the service. Multiple Sessions The DECserver 200 allows each user to establish and maintain up to 8 sessions to one or more service nodes, up to a maximum of 64 per DECserver 200. Only one session per user can be active at a time. Through simple switching commands, the user can access the different sessions without repeating a login dialog each 4 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 time. Some operating systems may impose limits on the number of LAT sessions such a host will support. Multiple Session Management The DECserver 200 server allows direct communication with de- vices which support the TD/SMP protocol. This protocol provides the ability for the attached device to maintain screen and key- board context for the multiple LAT sessions which the DECserver 200 provides. By implementing the ability to directly communi- cate with this protocol to the attached device, the DECserver 200 can now assist in the management of context of these mul- tiple sessions, as well as allow for simultaneous output to multiple LAT sessions being maintained by the device. Outbound Connection Queues If a terminal user requests a connection to a server, and the requested service is currently in use, the terminal server users may opt to have the connection requested queued to the remote service. This feature will happen automatically whenever a connection fails for this reason if the user's port has been appropriately configured. The connection request is queued at the service node end and is processed first-in/first-out until such time as the user's connection request can be completed. This feature assists in the fair management of limited net- work resources. Once queued for connection, the user also has the option to cancel the queue entry and proceed with other sessions. Welcome Identification The DECserver 200 server standard Welcome banner which includes terminal server type, version number, internal baselevel, and protocol version number is issued whenever a user successfully logs in to the server. The server will also print a server manager settable identification string. This can be useful for automatic server identification, or for small daily messages used for communication with the terminal server users. 5 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 Local Mode and Service Mode For the most part, the environment provided by the DECserver 200 is identical to that the user would experience if attached directly to the service node. When operating in this mode, the user is said to be in Service Mode. Occasionally, such as during connection establishment, the user interacts directly with the DECserver 200. When operating in this mode, the user is in Local Mode. In Local Mode, the terminal input is interpreted directly by DECserver 200 as commands to be performed by the server. The local mode prompt can be modified as a privileged command and therefore changed from LOCAL> to any printable characters (up to 16). Local Mode has three different levels of privilege: privileged, nonprivileged and secure. Privileged mode is provided for the Server Manager to control the environment of the server and the terminal users. Access to this mode is password protected. nonprivileged commands allow the terminal user to control their service sessions, set their terminal characteristics and show server information. The Server Manager can set the server to secure mode on a per-terminal basis which further limits the commands users can enter to only those which directly relate to the user's own terminal. The Server Manager environment is a logical extension of the user environment. The Server Manager is treated as a server user with a privileged status. The Server Manager sets a terminal to this status using a command which requires a password. This privileged status allows the Server Manager to enter commands not normally available to server users. These commands set server characteristics, provide control over server port usage, and provide the ability to control the user's access to the server and network services. 6 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 In Service Mode, the terminal input is passed directly to the connected service node with several exceptions. One exception, called the local switch character, allows the user to enter Lo- cal Mode from Service Mode. The key may also be used for this function. Other exceptions, called the forward and backward switch characters, allow the user to switch between sessions without the need to enter local mode. The switch characters are disabled by default but may be enabled by command. Both CTRL/S and CTRL/Q are normally interpreted locally but flow control using these characters can be disabled. Autoconnection Autoconnection is a function that automatically connects a user terminal to a service node when connection failures occur or upon user login to the server. In conjunction with this function, a dedicated or preferred service can be specified for each terminal user. If a dedicated service is specified, the DECserver 200 will attempt to connect to that service when a character is typed on the terminal keyboard or when an existing connection fails. In dedicated service mode, only one session is available. As this mode is designed to simulate a direct terminal connection, no local mode commands or messages are available to the terminal user. Ports with dedicated service can be automatically logged out of the server when the user logs out of the service node. If a preferred service is specified, the DECserver 200 will attempt to connect to that service as with the dedicated service mode of operation. However, the terminal user can enter local mode and establish other sessions. Automatic Session Failover If a service is available on two or more service nodes and a connection to a service fails, the server will attempt to connect the user to another service node offering the same service. The user does not have to be already connected to that service node. Furthermore, the user's context at the time 7 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 of failure is not automatically restored and login to the new service is required. Groups Every terminal and service node in a LAT network is a member of one or more groups, which are specified by a list of numbers from 0 - 255. Groups allow an easy means of subdividing the net- work into what appears to be many smaller networks. A terminal user is only aware of the services that are offered by nodes in the same group(s). The Server Manager can specify the authorized group(s) in which a terminal is a member. The authorized groups define the set of services that the user is allowed to access. In addition, a user can further restrict access to services by disabling some of the authorized groups using a nonprivileged group command. The user-settable group codes are a subset of the authorized groups. Groups provide a restrictive view of the network. This re- stricted view is mainly for user convenience and, although it also provides a form of security, it is not intended to be the primary form of access authorization or system security for a node. Security The DECserver 200 provides functions which enhance security features already available in the service nodes. DECserver 200 security includes the ability to lock a terminal's keyboard from other users, optional login protection, and nonprivileged local mode of operation as a default. A user may lock the terminal using a lock password. This allows the user to leave sessions running at the terminal without fear of security violations. When a terminal is locked, all input from the terminal is ignored until the lock password is re- entered. The lock feature may be disabled by the Server Manager. 8 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 Each terminal port can be set to operate in a secure mode which causes all commands that relate to other users to be disabled for that port. Login passwords can be enabled on a per-line basis by the server manager. If enabled, the terminal user must enter a login pass- word to access server functions. DECserver 200 users normally have access to the nonprivileged local mode. In this mode, users may only issue commands that af- fect their own terminal environment. The server has a privileged mode for server manager's use. The mode is password protected. Online HELP Facility A full online reference HELP facility is available. The server's HELP command provides information on the correct syntax and details about each command. In addition, a tutorial HELP feature allows new users to quickly learn the basics of DECserver 200 operation. Tutorial HELP may be entered upon logging into the server. Directory Service Any DECserver 200 user can obtain a directory of services avail- able to that user with a SHOW SERVICES command. Services for which the user is not authorized will not be displayed. Permanent Characteristics The DECserver 200 maintains permanent characteristics in non- volatile memory which is retained even when the power is dis- connected. Permanent characteristics are maintained for service and server parameters as well as per-port parameters. Permanent characteristics can be reset to factory defaults by pressing the software reset button on the hardware unit while plugging in the power cord. Port Characteristics Configuration 9 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 Characteristics governing the operation of an individual port can be displayed by a nonprivileged terminal user interactively from their terminal. Many of the characteristics may be set-up by the user, but certain characteristics are privileged and may only be changed by the Server Manager. Port parameters that can be set and displayed include: speed, character size, group codes, parity, terminal type, access, autobaud, modem and password protection. Port Access A port on a DECserver 200 may be set up in different ways de- pending on the device attached to the port and its intended use. DECserver 200 supports RS-232C and DECconnect asynchronous devices operating at speeds up to 19.2K bps. Port access is the characteristic which determines how a port may access or be accessed by interactive users and service nodes. o Access Local - Used for interactive terminals. This allows the device (typically an interactive terminal) attached to the port to CONNECT to LAT services. This type of access is also used for dial-in modems. o Access Remote - Designed for applications-driven devices such as asynchronous printers which are allocated by a service node process. This allows the implementation of certain shared printers by multiple service nodes. This type of access is also used for connections to dial-out modems, and non-LAT host systems. o Access Dynamic - Designed for devices (such as personal computers or printers with keyboards) which require both Local and Remote access. o Access None - Designed to allow the server manager to disable the use of a port. 10 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 With printer support capabilities, the particular server port must be configured for remote access and set up to match the characteristics of the printer. The server can optionally queue remote connects if these connects cannot be satisfied immedi- ately. This queue management can be enabled for the server by the server manager. Note that this is a connection queue only. Terminal Operation The DECserver 200 software supports the simultaneous operation of up to eight asynchronous devices at speeds from 75 bps to 19.2K bps. The software also supports: o Full modem control support (DECserver 200/MC only) o Data leads only support o XON/XOFF flow control o CTS/RTS and DSR/DTR flow control (DECserver 200/MC only) o Split speed (transmit and receive) terminal operation o Modem fallback features (DECserver 200/MC only) o Block Mode transfers o Automatic line speed detection o Digital personal computer file transfer o Data transparency mode o Ability to pass break character and error notification o Ability to assist in multiple session management via TD/SMP. Terminals Supported The DECserver 200 software supports the following Digital termi- nal devices that have keyboards: o LA12, LA34, LA35, LA36, LA38, o VT52 11 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 o VT100, VT101, VT102, VT125, VT131 o VT220, VT240, VT241 o VT320, VT330, VT340, VT380 Supported terminal parameters are: o Character size: 7 or 8 bits per character o Parity: Even, Odd, Mark, or None The automatic line speed detection (Autobaud) feature is sup- ported for either seven-bit characters with even parity or eight-bit characters with no parity. The DECserver 200 software also supports the following Digital personal computers (PCs) in both terminal emulation mode and file transfer mode: o Professional 325, 350, 380 o Rainbow 100A, 100B, 100+, 190 o DECmate II o DECmate III o VAXmate Note: This product is NOT WARRANTED to support non-Digital ter- minal devices or personal computers. However, terminals support- ing VT100 or VT200-like characteristics and personal computers supporting IBM[R] PC, IBM PC/XT, and IBM PC/AT characteristics may operate with this product. Modems Supported For DECserver 200/MC: o DF01, DF02, DF03, DF112, DF124, and DF224 full-duplex asyn- chronous modems for either dial-in or dial-out use. Also supported are private or leased line modem applications. 12 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 For DECserver 200/DL: None Server Management Several facilities exist for managing and troubleshooting server operation. The Server Manager in privileged mode can set up server identification information, change port characteristics, or fine tune the operating characteristics of the server. The Server Manager can also assign service names to groups of one or more ports which are connected to non-LAT hosts or modems. Troubleshooting facilities include diagnostic tests, a remote console feature, and online statistics. A privileged user can diagnose Ethernet communications prob- lems by looping messages to an Ethernet host and through the Ethernet hardware interface at the server. To diagnose terminal problems, users can execute a command to transmit test data to their terminal, or the server manager can send test data to any terminal. The capability also exists for the server manager to test a service connection by sending data from the initiating port to the service node and back again. The data is then compared and any discrepancies reported. At the service node, the data can be looped back by the LAT protocol, or internally or externally at the service port. This feature is supported only by DECserver 200 service nodes; RSX-11M-PLUS and Micro/RSX service nodes do not support this service loopback capability. The server maintains a variety of statistics and counters. These include the following: Ethernet data link statistics, LAT pro- tocol statistics, and port error statistics. These data can be displayed and zeroed by the Server Manager. Server param- eters that can be modified and displayed include the server identification, circuit timer, session limits, and login limits. Remote Server Management 13 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 The DECserver 200 implements the console carrier feature which enables access to the DECserver 200 local mode from a Phase IV DECnet host on the same LAN. With the exception of remote con- sole port configuration, the entire local mode user interface is accessible to the remote console carrier user. This includes the privileged commands, if the user knows the server's privileged password. This capability allows centralized server management and remote server diagnosis. Communications DECserver 200 software is designed to run on DECserver 200 hardware exclusively which includes an Ethernet interface for connection to an Ethernet transceiver cable. The DECserver 200/MC has eight EIA RS-232-C/CCITT V.24 asyn- chronous line interfaces for connecting terminals to the unit. The DECserver 200/DL has a single 36 pin DECconnect connector for 8 ports. On the DECserver 200/MC, each port on the server can be set up by the Server Manager to operate using full-duplex modem control. The DECserver 200/MC is compatible with Digital's family of modems and with Bell 100 and 200 series modems and their equivalents. A BREAK feature is available and can be set on a per-port basis. This allows the DECserver 200/MC to force a break condition on connections to host interfaces. BREAK can also be passed through from a terminal connected on the server to the non-LAT host connected on the server. DECserver 200 Operation The DECserver 200 ROM-based firmware provides the necessary maintenance operation protocols for downline loading DECserver 200 software from a Phase IV DECnet load host over the Eth- ernet into server memory. All self-test diagnostics are in DECserver ROM, so downline loading is not a precondition for DECserver self-test. In the event of a bugcheck caused by a fa- tal error, the unit will normally attempt to upline dump server 14 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 memory to a DECnet Phase IV host. Following this, the unit will automatically initialize itself and invoke a downline load. Additional Features The DECserver 200 terminal server provides additional features for VMS service nodes running LATplus/VMS. Refer to the Software Product Description for VMS (SPD 25.01.xx) for more information. DECserver 200 Configuration and Performance The process of configuring the DECserver 200 is based primarily on tradeoffs of cost and performance within the realm of satis- fying user application requirements. Network applications will range from low-speed, low-cost situations (e.g., connecting re- mote terminals through low-speed modems) to those of relatively high performance (e.g., connecting high-speed local terminals to local hosts within a local area network or connecting to non-LAT systems). The performance of a given server is a function of the expected network traffic, the load on hosts to which ter- minals are connected, and resultant processing pursuant to the dedicated function of the unit. Thus performance depends on several factors: o Number of terminals o Number of host systems with active connections to the server o Number of active connections to non-LAT hosts o Terminal speeds o Terminal user applications o Number and size of host buffers o Terminal workload The DECserver can sustain an aggregate character throughput of over 11520 characters per second. This is equivalent to running 4 ports at 19200 bits per second, and 4 at 9600 bps. 15 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 In order to achieve a viable configuration, the user and/or a Digital software specialist should perform a level of appli- cation analysis which addresses the factors above. The actual maximum data throughput cannot be calculated by multiplying the number of lines by the line speed, since many factors already discussed in this section may reduce the actual throughput. Restrictions on DECserver 200 Usage While terminal connections using the DECserver 200 have been designed to simulate direct terminal connections as much as pos- sible, a few differences necessarily exist because of the nature of the product. Under most circumstances, these differences are not noticed by terminal users or service node application pro- grams. However, applications which are directly dependent on the following functions may not operate as with a direct connection: o Applications that depend on reading or setting the terminal speed, character size and parity by manipulating system data structures o Applications that depend on an extremely fast response time (typically less than 200 ms) to operate o Applications that utilize an alternate terminal driver in the service node o Applications that expect incoming connections to have fixed device names 16 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 HARDWARE REQUIREMENTS The DECserver 200 software runs on either of the following packaged hardware options: DSRVB- DECserver 200/MC hardware, including eight EIA AA/AB RS-232-C/CCITT V.24 asynchronous ports supporting speeds up to 19.2K bps, factory set at 120V/240V. DSRVB- DECserver 200/DL hardware, including eight DEC- BA/BB connect asynchronous ports supporting speeds up to 19.2K bps, factory set at 120V/240V. Use the following SHIELDED cables with each of the physical lines on the DECserver 200/MC unit: BC22D Null modem cable for local terminal connections. BC22E Full modem straight through cable for modem connec- tions. BC22F Full modem straight through cable for modem connec- tions. BC22R Recommended null modem cable for host systems and other devices, including those which utilize CTS/RTS flow control. BC17D Null modem cable for host systems and other devices which do not utilize CTS/RTS flow control. Use DECconnect cables with the DECserver 200/DL unit. The DECserver hardware requires both a transceiver drop cable and Ethernet connection, H4005 or DELNI, to connect to the Ethernet physical channel. All software run on the DECserver is downline loaded over the Ethernet from a Phase IV DECnet load host. 17 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 Disk Space Requirements (Block Cluster Size = 1): Disk space required for 950 blocks installation: Disk space required for 950 blocks use (permanent): The block space requirements above refer to the disk space required on the downline load host system disk. The sizes are approximate; actual sizes may vary depending on the user's system environment, configuration, and software options. GROWTH CONSIDERATIONS The minimum hardware/software requirements for any future ver- sion of this product may be different from the minimum require- ments of the current version. OPTIONAL HARDWARE None SOFTWARE REQUIREMENTS For Load Hosts and Service Nodes: For PDP-11 Systems RSX-11M-PLUS Operating System and DECnet-11M-PLUS For MicroPDP-11 Systems RSX-11M-PLUS Operating System and DECnet-11M-PLUS or Micro/RSX Operating System and DECnet-Micro/RSX Refer to the RSX-11M-PLUS and Micro/RSX Optional Software Cross Reference Tables (SPD 20.99.xx and SPD 20.95.xx) for the re- quired versions. 18 DECserver 200 for RSX-11M-PLUS and Micro/RSX, SPD 15.72.03 Version 3.1 For RSX-11M-PLUS and Micro/RSX, LAT service node support is provided with DECnet. Hence, it is necessary that DECnet be installed and running on all RSX-based LAT service nodes. RSX-11M is not supported either as a LAT service node, or as a load host. The DECserver 200 software is installed on an RSX-11M-PLUS or Micro/RSX load host, which must contain DECnet-11M-PLUS or DECnet-Micro/RSX (Phase IV), respectively. DECnet is used for downline loading the server software into the DECserver 200 units. The DECserver 200 server software will operate with all Digital service nodes which support the LAT protocol. All features de- scribed in this SPD will operate with RSX-11M-PLUS and Micro/RSX service nodes. Additional features are available for VMS service nodes running LATplus/VMS, which is included with the DECserver 200 distribution and documentation for VMS load hosts. The DECserver 200 software license applies to the DECserver 200 on which the server software runs, not to service host node CPUs in the network.
