INTRODUCTION

1.3 LOCAL MANAGEMENT FOR THE CABLETRON SYSTEMS IRM

Cabletron Systems Local Management for the Cabletron Systems IRM provides unique network management and control capabilities for a Cabletron Systems Multi Media Access Center (MMAC) with an IRM installed. With Local Management, you have full control of your network.

Local Management provides the network manager with many tools to control and manage the MMAC and its attached segments. By setting various threshold v alues (Alarm Limits), you can be advised that a certain condition has been reached. When an alarm limit has been reached, an MMAC can be set to advise you that the condition has been reached or set to automatically reroute network trafﬁc.

For example, if you want to know if the MMAC processes a speciﬁc number of good packets or collisions over a set period of time (e.g., 2000 packets in 1 second), an MMAC Limit can be set to notify you that this condition has been reached. Limits can also be set for each individual board (Board Limits) and for each individual port (Port Limits). These limits can be set to disable the MMAC, board, or port when the limit is reached.

If these limits are set to turn off the MMAC, board, or port, Local Management allows you to reroute network trafﬁc automatically. This feature is called call redundancy. Redundancy keeps your network up and running at all times. For example, if a limit set for a port is reached and the port is set to turn off automatically, a backup port can be set to pick up network trafﬁc automatically from the disabled port.

Local Management also gives you the ability to gather a vast amount of statistical information about the MMAC at three increasingly detailed levels: for the MMAC as a whole, for each board, and for each port.

Statistical information on the MMAC is broken down into three categories: packets, collisions and alarms. Totals for each of these categories are recorded at the MMA C, board, and port le vel. This data can be sampled at two user-deﬁned interv als—a time-based interval calibrated to the second, and a total packet count interval calibrated to one packet. These statistics illustrate how packets, collisions, and alarms correlate over time.

GETTING STARTED

This chapter lists procedures for entering the password so you can access Local Management for the IRM. It also provides the terminal and cable conﬁgurations for setting up a terminal for accessing Local Management. Instructions are included for exiting Local Management.

2.1 TERMINAL CONFIGURATION

Local Management for the IRM is accessed through a VT™ 100 Series terminal, a Prime™ 200 Series terminal, or a compatible system running an emulation program. The terminal is attached to the port labeled CONSOLE on the IRM by an RS-232 cable. For instructions to set up your terminal, refer to the applicable node user's manual.

The terminal conﬁgurations must be set as follows so the terminal can communicate with Local Management.

2.2 CABLE CONFIGURATION

Local Management is accessed by a modiﬁed RS-232 cable, available from Cabletron Systems. This cable connects the terminal to the IRM's Console port.

The pin out for a cable with a 25 pin connector at the terminal end of the cable, and a 9 pin connector at the MMAC end of the cable, should be conﬁgured as follows:

2.2.1 VT100 Series

9 Pin Male Connector to 25 Pin Female Connector (MMAC End) (Terminal End)

Pin 1 (Receive) to Pin 2 (Transmit) Pin 4 (Transmit) to Pin 3 (Receive) Pin 5 (Ground) to Pin 7 (Ground) Pin 6 (Request to Send) to Pin 5 (Clear to Send) Pin 9 (Clear to Send) to Pin 4 (Request to Send)

2.3 ACCESSING LOCAL MANAGEMENT

This section contains instructions for attaching the terminal to the IRM, and for accessing Local Management through the IRM's Console port. This procedure assumes that the special 9 to 25 pin RS-232 cable, provided by Cabletron Systems, is being used to connect the terminal to the IRM.

1. Plug the 9 pin end of the RS-232 cable into the RS232 port labeled CONSOLE on the IRM.

2. Plug the 25 pin end of the RS-232 cable into the COMM port on the terminal.

3. Turn the terminal on. The Terminal Type Menu Screen, Figure 2-1, will appear, prompting you to select the terminal type.
