[c-nsp] 802.1q trunking from cat6509 to 2950T-24

[Marko Milivojevic]

Why do you insist on tagging native VLAN? If there is no special reason to do it, don't :-)

Solution for your problem is to make some other (unused) VLAN native on the 2950. That way, it will tag VLAN 1 over the trunk.

Hi,

I am having difficulty establishing 802.1q trunk to 2950 switch.

I am only (initailly) trying to establish VLAN1 across trunk.

I have 'vlan dot1q tag native' configured on the 6509 side but I dont 
have a similar command on 2950T-24 or a way to untag the native on a per
trunk  
basis on the 6509.

Configs below:

6509:
!
vtp mode transparent
vlan dot1q tag native
!
interface GigabitEthernet1/14
description 802.1q Switch1 Access
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-599,601-4094
switchport mode trunk
switchport nonegotiate
no ip address
logging event link-status

2950T-24:
!
vtp mode transparent
!
interface GigabitEthernet0/1
description 802.1q<-->-6509-01[Gig1/14]
switchport trunk allowed vlan 1-599,601-4094
switchport mode trunk
switchport nonegotiate
no ip address

Am I missing something?

Thanks,
Mark
