I have an non-Cisco L2 switch that needs to connect to a Cat 6509 via etherchannel using LACP. How do I assign a VLAN/dot1q encapsulation on the etherchannel/port-channel on the Cat6509 to identify the VLAN.
Here's my config;
6509-SW-01#sh run int fa3/15
Building configuration...
Current configuration : 154 bytes
!
interface FastEthernet3/15
description Kat testing--Sourcefire Mgmt
no ip address
shutdown
channel-protocol lacp
channel-group 15 mode active
end
6509-SW-01#sh run int fa3/16
Building configuration...
Current configuration : 113 bytes
!
interface FastEthernet3/16
description Kat testing--Foundry
no ip address
channel-group 15 mode active
end
6509-SW-01#sh run int port 15
Building configuration...
Current configuration : 47 bytes
!
interface Port-channel15
no ip address
end
6509-SW-01#

I'm assuming you're going to have multiple vlans going over that port-channel. I'm having a similar issue.
I create the port-channel and then the sub-interface. Then when I try using the command:
encapsulation dot1Q 161
I get an error:
Command rejected: VLAN 161 not available
The problem is that vlan 161 has been created and is active.

Were you able to create the sub-interface on the port-channel. The problem in my case is that VTP is enabled and cannot create a new VLAN.

It goes under the port channel interface. Native vlan has to match on each side. there are no sub interfaces involved .
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan XXX
switchport trunk allowed xxx,xxx,xxx

OK... I've gone and created the vlans as interfaces instead and assigned them the ip addresses, etc.
The problem now is that when i go onto the interface that is going to be the trunk and try using
switchport mode trunk
I get an error:
command rejected: Po37 not a switching port
I thought maybe it had to do with the fact that I was trying to do it on a port-channel, but i get the same issue while trying to use the command on a physical interface as well.
This is on a 6509 also.

Ahh... Nevermind. Just using the command switchport first allows you to set it up.
Thanks for the info Glen.
