Information in this document applies to any platform.

Symptoms

Infiniband interface show in listlinkup as "up (Disabled)"

Cause

The link was disabled and enabled using different commands

If the link is disabled using the disableswitchport:

Example:

# disableswitchport 11

Then enabled using the ]# ibportstate command:

Example:

# ibportstate -D 0 11 enable

The link will display as follows:

Connector 12A Present <-> Switch Port 11 is up (Disabled)

NOTE: If the switch were to be reset when in this state, this port will be down after the reset:
Connector 12A Present <-> Switch Port 11 is down (Disabled)

Solution

To resolve this, use the following command:

# enableswitchport 11

This will re-train the port and report the correct status.

Note: The link will go down and come back up when this is done

You should only use the disableswitchport and enableswitchport and not use the "ibportstate" command!
