HP J3188A manual POrt port ON/OFF, REset, RObustness

Managing the Hub

Console Command Reference

POrt <port> <ON/OFF>

To enable (set to ON) or disable (set to OFF) a hub port. The initial setting for all ports is enabled (ON). You can use the Status command to check the current status of all the ports. The <port> parameter can be:

■twisted-pair port number

■XCVR or XC for the AUI port

■ALL or AL for all ports

Example 1: P0 7 OFF (Disables port 7)

Example 2: P0 AL ON (Enables all ports)

REset

To reset the hub and run a hub self-test. This command also resets all the network statistic counters, and the time since the last reset. The current configuration is unchanged. The hub is not accessible from network manage- ment software while it is being tested, but it continues to repeat data. If the hub is faulty, at the end of the reset process, the Fault LED will stay on.

This command also terminates the console session (and disconnects the phone line if you are using a modem to access the console) and resets the console port baud rate to be automatically sensed. To restart the console session, first re-establish the phone link (if used), then press [Enter] several times for the prompt.

RObustness

Allows you to invoke options to improve the hub’s ability to tolerate network problems resulting from excessive collisions. The configurable options are:

■Intelligent Partition Recovery

■Late Collision Monitoring

By default, the robustness features are off. The Intelligent Partition Recovery option makes it difficult for a problem port to automatically re-enable itself to send traffic on the network.
