Management Module/GbESM Connectivity
Currently, the IBM management module is designed to provide one-way control of the GbESM. As
a result, the GbESM may lose connectivity to the management module via the management port
under the following conditions:
If new IP attributes are pushed from the management module to the GbESM while the IP
Routing table is full, the new attributes will not be applied.
Solution: Enable “External Management over all ports,” connect to the switch using other
interface and then clear the routing table. Then push the IP address from the management
module. If this does not work, use Solution 2 below.
If you execute the /boot/reset CLI command on the GbESM or the GbESM resets itself, the
management module might not push the IP attributes to the switch, and connectivity may be
lost.
Solution 1: If you should experience any connectivity issues between the switch module and the
management module, go to the “I/O Module Configuration” window on the management module’s
Web interface. Under the “New Static IP Configuration” section, click
Save
to trigger the
management module to push the stored IP attributes to the switch module.
Solution 2: If Solution 1 does not resolve your connectivity issue, then go to the “I/O Module
Admin/Power/Restart” window on the management module’s Web interface. Restart the switch
module in question.
Solution 3: If this still does not resolve the issue, enable Preserve new IP configuration on all resets
setting on the management module and restart the switch module via the “I/O Module
Admin/Power/Restart” window on the management module’s Web interface.
Note –
As a rule, always use the management module Web interface to change the GbESM
management IP attributes (IP address, mask and gateway), and then click Save to push the IP
attributes to the switch module. Use of the command-line interface to change the switch module
management IP attributes may result in duplicated entries for the management IP Interface in the
switch route table and/or loss of connectivity via the management module.
