Thanks, Bob. This was interesting now that you mention the order. I redid
this a couple of times, and actually defaulted both switches. I think I was
doing the way you state, ......(can you explain the part of your response
"doing the physical port configuration only...can you detail what you did?).
Here is what I did......
CAT1(config)# interface range fa0/13 - 14
CAT1(config-if)# switchport trunk encapsulation dot1q
CAT1(config-if)# switchport mode trunk
CAT1(config-if)# channel-group 1 mode desirable
CAT2(config)# interface range fa0/13 - 14
CAT2(config-if)# switchport trunk encapsulation dot1q
CAT2(config-if)# switchport mode trunk
CAT2(config-if)# channel-group 1 mode auto
This did not work until I did the following.... all the vtp information was
correct, by the way.
CAT1(config)# interface port-channel 1
CAT1(config-if)# speed 100
CAT1(config-if)# duplex full
CAT2(config)# interface port-channel 1
CAT2(config-if)# speed 100
CAT2(config-if)# duplex full

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?
