[c-nsp] Problems sub-interface Catalyst 6500

[Alexandra Alvarado]

Hello,

 

I would like to know if It's possible to add the same vlan id on two
different interfaces, I am using a Catalyst 6500 switch (Version
12.2(18)SXD6).  The question is because if I try to add encapsulation dot1q
2 on a sub-interface that belong to another interface, I get the following
error:

 

interface GigabitEthernet7/1

 description 3550-S1

 mtu 9216

 no ip address

 no ip proxy-arp

 

interface GigabitEthernet7/1.1

 encapsulation dot1Q 2

 ip vrf forwarding VRF00001

 ip address 10.201.15.254 255.255.255.252

 

interface GigabitEthernet7/2

 description 3550-S2

 mtu 9216

 no ip address

 no ip proxy-arp

 

TELEPUERTO#config term

TELEPUERTO(config)#interface gigabitEthernet 7/2.1

TELEPUERTO(config-subif)# ip vrf forwarding VRF00001

TELEPUERTO(config-subif)#encapsulation dot1Q 2

Command rejected: VLAN 2 not available

TELEPUERTO(config-subif)#

 

 

Thanks
