Group,
I am trying to setup a Port-Channel between Cisco 7600 and Sun CT900 which has CP3140 switch, but it is not working.
It seems that Sun switch is sending "Fast" LACPDUs while Cisco 7600 is sending "Slow" LACPDUs (as shown below).
Is there a way to force Cisco 7600 to send "fast" LACPDUs.
C7606-1#show lacp 11 neighbor
Flags: S - Device is requesting Slow LACPDUs
F - Device is requesting Fast LACPDUs
A - Device is in Active mode P - Device is in Passive mode
Channel group 11 neighbors
