Dave,
The configuration looks right, but order does matter. When you do "show
interface status" do you see f0/13 or f0/14 shown as "suspended" on either
side? If so, shut and default the four interfaces. Recreate the channel
doing the physical port configuration ony. This will create the Port Channel
interface. Once this is working, do all trunking configuration on the
PortChannel interface. Works for me.
HTH,

Subject: Etherchannel issues
I know I have done this a million times before, but am running into some
issues. I am setting up vtp server/client between two cats with
etherchannel,
using fa0/13 and fa0/14 and having problems. Here is a section of the show
etherchannel detail (I am trying to find more info on the flags on docCD
and
not finding it)....
Local information:
Hello Partner PAgP Learning Group
Port Flags State Timers Interval Count Priority Method Ifindex
Fa0/14 SAC U6/S7 HQ 30s 1 128 Any 29
Here is the config....
CAT1.....
!
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
!
(output omitted)
!
interface FastEthernet0/13
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode desirable
!
interface FastEthernet0/14
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode desirable
!
CAT2....
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
!
(output omitted)
!
interface FastEthernet0/13
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode auto
!
interface FastEthernet0/14
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode auto
!
The vlan information is not being sent from CAT1 to CAT2 through VTP.
Maybe
this is a bug in the software? Maybe I'm just missing something. Is there
some strange order that needs to happen to initiate the etherchannel?
Dave
