[c-nsp] Cat 4006 Etherchannel plus VLAN trunking?

[Ravi Patwari]

Hi Jeremy,

Please  see the amended configuration below:

interface Port-channel2
 switchport
 switchport mode trunk
 switchport trunk encapsulation dot1q
 

interface GigabitEthernet3/1
 switchport mode trunk
 switchport trunk allowed vlan 2,5,10,15
 switchport trunk encapsulation dot1q
 channel-group 2 mode desirable


interface GigabitEthernet3/2
 switchport mode trunk
 switchport trunk allowed vlan 2,5,10,15
 switchport trunk encapsulation dot1q
 channel-group 2 mode desirable
 
It should do the trick. You can even remove the allowed vlan lines and once
the trunk works you can then add the selected vlans config.

Regards
Ravi

I'm having difficulties getting multiple VLANs to trunk across an
Etherchannel on a pair of identical Catalyst 4006 switches (IOS
12.2(20)EWA).

I can configure Etherchannel with a single VLAN, and I can also
configure trunking across a single link. However, when I try to combine
the two, traffic won't pass between the switches.

If someone could please send me an example of a working config (or fill
in the blanks of the config below), I would be extremely grateful.


Thanks,
