Monitoring and Managing Your ELS10-26

4.5.1 Disabling a Port

There can be times when you need to disable a specific Ethernet port, for example, after you have determined that there is faulty equipment. Disabling a port effectively stops all bridging functions for that port. Disabled ports do not accept SNMP packets, and therefore cannot communicate with an NMS.

To disable a port, or port range, at the LCM prompt:

1.Type disable <PORT-RANGE>

For example, disable 7-9would disable ports 7, 8, and 9.

LCM responds:

Port 7: Disabled

Port 8: Disabled

Port 9: Disabled

Once an Ethernet port is disabled, it will be disabled until you enable it again. Resetting the ELS10-26 will not enable a port that has been disabled.

Caution: If you disable the port through which someone is remotely managing the ELS10-26, that person will not be able to communicate with the ELS10-26. Use the LCM command addresses display to find the port number you are using to manage the ELS10-26.

4.5.2 Enabling a Port

When you enable an Ethernet port that has been disabled, whatever bridging functions you had previously configured for that port are re-enabled.

To enable a port, or a range of ports, at the LCM prompt:

1. Type enable <PORT-RANGE>
