2600 not able to add vlan envapsulation

jasosan22 · ‎03-06-2009

I have a 2600 and I am trying to configure subinterfaces on a f0/0 port. I read that my code supports vlan encapsulation but when I try to add encapsulation 802.1d to the interface the command is non-existant. Here is the show ver and the error message:

Hi

802.1d is spanning-tree, I think you want 802.1q or ISL for your encapsulation.

Should be configured something like this.

7500(config)#int fast 5/1/1.1

7500(config-subif)#encapsulation dot1Q 1 native

7500(config-subif)#ip address 10.10.10.1 255.255.255.0

7500(config-subif)#exit

7500(config)#int fast 5/1/1.2

7500(config-subif)#encapsulation dot1Q 2

7500(config-subif)#ip address 10.10.11.1 255.255.255.0

7500(config-subif)#exit

Thanks but the encapsulation command doesn't exist. I verified that the router/code supports vlan encapsulation but it isn't allowing me to enter the encapsulation command.

Are you try to use the encapsulation command on a fastethernet interface?

HTH,

yes it is the on-board f0/0 and f0/1

You don't have the right feature set. You have IP/FW/IDS which does not support 802.1q. IP Plus & Enterprise do. Have a look at Feature Navigator to select correct feature set for your needs -
