Folks, I have a L2 etherchannel link between 2 switches. Both sides are configured with "ON" type. The etherchannel establishes and I can see VTP status messages getting exchanged for any VLAN changes. I established this EC with the command "channel-group 1 mode on" on the interfaces.
I wanted to try different modes and I ran into a probem. Check out the below logs:
SW1(config-if)#
2w2d: %EC-5-ERRPROT2: Command rejected: the interface Fa0/23 is already part of a channel with a different type of protocol enabled SW1(config-if)#channel-protocol pagp SW1(config-if)#
2w2d: %EC-5-ERRPROT2: Command rejected: the interface Fa0/23 is already part of a channel with a different type of protocol enabled SW1(config-if)#^Z SW1#show e
2w2d: %SYS-5-CONFIG_I: Configured from console by consolether SW1#show etherchannel port
Channel-group listing:
-----------------------
Group: 1
----------
Ports in the group:
-------------------
Port: Fa0/23
------------
Port state = Up Mstr In-Bndl
Channel group = 1 Mode = On/FEC Gcchange = -
Port-channel = Po1 GC = - Pseudo port-channel = Po1
Port index = 0 Load = 0x00 Protocol = -
Age of the port in the current state: 00d:00h:27m:12s
Port: Fa0/24
------------
Port state = Up Mstr In-Bndl
Channel group = 1 Mode = On/FEC Gcchange = -
Port index = 0 Load = 0x00 Protocol = -
Age of the port in the current state: 00d:00h:22m:40s
SW1#
SW1#
The porotcol mode shows "-" ??!!! ... and I cant explicitly set it to Pagp or Lacp. Any comments ?
Thanks in advance.
