16 Chapter 1 Introduction What Is in This Chapter This chapter describes the SPECTRUM Management Module for Xylogics Terminal Server devices. It also provides the model type names assigned to the Xylogics Terminal Server devices in SPECTRUM. The model type names refer to the template used to specify attributes, actions, and associations for device models in SPECTRUM. SPECTRUM and the Xylogics Terminal Servers The Cabletron Communications Server (CSMIMII) is a Xylogics Annex III software compatible system designed to reside in the MMAC series of Cabletron hubs. The CSMIMII integrates a communications server with remote dial-in capabilities into the hub and allows terminals and serial devices to be connected directly to Ethernet LANs. The CSMIMII provides from 16 to 32 asynchronous ports to connect serial devices to host computers on a LAN network. The CSMIMII-16 is upgradeable to a CSMIMII-32 or to a MODMIM-4. The MODMIM-4 is a 20 port communications server with 16 asynchronous ports. The MODEXT-8 upgrades the MODMIM-4 to create a 28 port server with 16 asynchronous ports and 12 modems. The 24 and 28 port communications servers use 2 adjacent slots in the MMAC hub E2 1-1

20 Chapter 2 Device View What Is in This Chapter This chapter provides a description of the Device View for the Xylogics Terminal Server Management Module, including a description of menu bar access to the various views used to control and monitor the devices. It also describes how to use the Device View to view the logical representations of Xylogics Terminal Server devices, access SPECTRUM generic views, and monitor terminal server performance. These Device Views show the logical representations of the Xylogics Terminal Server device s interfaces and provides you with menu bar access to the views that monitor and control the Xylogics Terminal Server device s interfaces. The Device View gives an actual representation of the Xylogics Terminal Server device s configuration. If the configuration changes you see the corresponding change within this view. This change in the view occurs after the model s next polling cycle. Accessing the Device View The Device View is accessed by using one of the following methods: E2 2-1

36 Serial Port Logical Interface Icon CLI Line Editing Parameters View This view provides the following information about CLI line editing functions: Echo Enabling this parameter echoes all characters as they are typed. The default is Disabled. Hardware Tabs Enabling this parameter allows the terminal to expand ASCII tab characters if the terminal does not support hardware tabs. This parameter only effects CLI. The default is Enabled. Telnet CRLF Enabling this parameter translates a carriage return into a carriage return followed by a line feed. Disabling this parameter translates a carriage return into a carriage return followed by a null string. The default is Disabled. Map To Upper Enabling this parameter converts case from lower to upper for characters sent from a terminal to the terminal server. This parameter is enabled for older terminals that do not support upper case characters. The default is Disabled. Map To Lower Enabling this parameter converts case from upper to lower for characters sent from a terminal to the terminal server. This parameter is enabled for older terminals that do not support lower case characters. The default is Disabled. Telnet Escape Defines the character that returns you to the telnet prompt when using the CLI telnet command. Setting this parameter to U disables the escape. The default is CTRL-] (^]). Redisplay Line Defines the reprint line character. The default is CTRL-R (^R). Toggle Output Defines the flush control character used to flush the output buffer. The default is CTRL-O (^O). Newline Echo Defines whether a carriage return is echoed as an enabled carriage return or a carriage return and line feed. Choices are CR and CR/LF. Attention Char Defines a control character sequence that returns you to the CLI prompt. Erase Char Defines the character erase control character sequence at the CLI level. The default is the Delete key (displayed as ^?); values may be displayed as one or two characters E2 Device View 2-17

37 Serial Port Logical Interface Icon Erase Word Defines the word erase control character sequence at the CLI level. The default is CTRL-W (^W). Erase Line Defines the line erase control character sequence at the CLI level. The default is CTRL-U (^U). Char Erase Enabling this parameter echoes the character or word erase character for a video terminal (the previous character looks like it has been erased). Disabling this parameter echoes the erase or word character for a hard copy terminal. The default is Enabled. Line Erase Enabling this parameter echoes line erase for a video terminal. It erases all characters on the line and moves the cursor back to the beginning of a line. Disabling this parameter echoes the line erase character for a hard copy terminal. It echoes the erase character and a new line so the deleted line is still visible. The default is Enabled. Serial Networking Parameters Click the SLIP/PPP Parameters button from the CSMIMII and MicroCS models to access the following parameters: General Parameters Port The selected serial port on this annex. Local IP Addr The Internet address for this port. The default is Remote IP Addr The Internet address for the host at the other end of the serial line. The default is Metric Defines the hop count to the remote end of the SLIP or PPP interface. Setting this object to 0 defaults to a value of 1. Phone Number The phone number used for this port when doing demand dialing. Net Inactivity The number of minutes allowed for serial protocol inactivity on the port. When the interval expires, the port is automatically reset. A value of 0 disables the timer. Device View Xylogics Terminal Servers 2-18 Management Module Guide

38 Serial Port Logical Interface Icon Dialup Addresses When enabled, the Annex requests the PPP dial-up addresses from the hostbased ACP. The default is Disabled. Demand Dial When enabled, allows the Annex to instruct the modem attached on the port to dial the phone number. SLIP Security This parameter controls dial up SLIP access. If enabled, and security is enabled on the Xylogics Terminal Server device, access to the slip command is restricted using the Access Control Protocol (ACP). The default is Disabled. Do Compression Enabling this parameter starts TCP/IP header compression on this SLIP link. The terminal server negotiates for TCP/IP compression on each connection. The default is Disabled. Allow Compression Enabling this parameter allows the terminal server to use TCP/IP header compression if the other end of the SLIP link initiates compression. The default is Disabled. Slip Parameters Subnet Mask The Internet subnet mask for the interface. The default is Load Dump Host The Internet address of the host from which the terminal server receives a load or to which the server dumps over the SLIP interface. The default is Allow Dumps Enabling this parameter allows dumping across a SLIP link. The default is Enabled. MTU Size This parameter sets the Maximum Transmission Unit (MTU) size on a compressed SLIP port. The possible MTU selections are large (1006) or small (256). The default is small. Discard ICMP Enabling this parameter discards any ICMP packets transmitted to the SLIP link to reduce unnecessary traffic. The default is Disabled. SLIP TOS Enabling this parameter provides type-of-service queuing on the SLIP link. The terminal server will transmit interactive traffic (e.g., telnet, rlogin, and ftp) before transmitting other traffic. The default is Disabled E2 Device View 2-19

39 Serial Port Logical Interface Icon PPP Parameters Remote Username The PPP ports user s name. The parameter is displayed as <set> or <unset>. The default is <unset>. Remote Password The PPP port user s password. The parameter is displayed as <set> or <unset>. The default is <unset>. MRU The Maximum Receive Unit (MRU) parameter. Values range from 64 to The default is ACM The Asynchronous Control Mask (ACM) parameter specifies which of the first 32 bytes (0x0 to 0x1F) can be transmitted as clear text and which should be protocol escaped before being transmitted. The default is 0x Protocol The PPP protocol running on the interface. Options are ipcp, atcp, and all; the default is all. Security Protocol This parameter requires remote users to pass a security check before communicating with the terminal server. The options are Password Authentication Protocol (PAP) or none.
