Severity: 3-Major


Sometimes,after mcpd get restarted, mcpd does not get management port NIC speed information from chmand; 'tmsh show net interface' might shows the speed of mgmt interface as 'none'.


The 'tmsh show net interface' commands cannot show correct management speed.


Management interface is up, and then restart mcpd.


You can resolve this issue by restarting the chmand process. On appliances (BIG-IP platforms), 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.
