Hi
One of my port-channel is showing as suspended because of one port, Speed and duplex are same at both side, can someone help to fix this, Advance thanks.
Below is the configuration
SWF1# sh port-channel summary interface port-channel 500
Flags: D - Down P - Up in port-channel (members)
I - Individual H - Hot-standby (LACP only)
s - Suspended r - Module-removed
b - BFD Session Wait
S - Switched R - Routed
U - Up (port-channel)
p - Up in delay-lacp mode (member)
M - Not in use. Min-links not met

If you do a sho int trunk, see if the VLAN's are allowed. Also make sure that the VLAN's are on both devices as layer 2.
