On a 4500 switch with two supervisors, two uplinks have been configured in etherchannel. One each from each supervisor.
When the uplink from second(standby supervisor) is removed, the connections drop and the port goes in err-disabled state. Seems it is disabled to udld.
How to enable it back.?
Also, why does the connection drop when the uplink from standby is taken out when primary is active & etherchannel is still with one active port in the channel.
Please help. Appreciate all help.
