Fixed In:

Opened: Aug 13, 2015
Severity: 4-Minor

Symptoms

Although the BIG-IP system's management port is up and working as expected, the tmsh utility may report no media for the management port, like in the following example: # tmsh show net interface mgmt -------------------------------------------------------------- Net::Interface Name Status Bits Bits Pkts Pkts Drops Errs Media In Out In Out -------------------------------------------------------------- mgmt up 13.5G 131.0M 11.2M 111.9K 0 0 none If the system is a VIPRION chassis, then it is possible for only some of the installed blades to be affected by this issue.

Impact

The BIG-IP system cannot display the management port's current media. For example, tmsh shows none as mgmt media in response to the following command: show net interface.

Conditions

This issue may occur if the mcpd daemon has restarted (due to a fatal error, or user command) while BIG-IP is running.

Workaround

You can resolve this issue by restarting the chmand process. On appliances, run the following command: bigstart restart chmand. On VIPRION systems, run the following command: clsh "bigstart restart chmand".

Fix Information

The tmsh utility now reliably displays the current media of the BIG-IP system's management port even if the mcpd daemon has restarted (due to a fatal error, or user command) while BIG-IP is running.
