VLAN for IOS 12.2(2)T1 ! ?

How to configure VLAN at routers with IOS 12.2(2)T1 ?

We know how to configure VLAN 802.1q at routers with IOS 12.1 and previous versions. But we can not find encapsulation related commands at IOS 12.2(2)T1. Where are they ?

Would be appreciated for any suggestions.

Thanks.

Re: VLAN for IOS 12.2(2)T1 ! ?

it's the same. also, the router will support isl encapsulation as well.

But there is no longer the command "encapsulation" exists in my IOS 12.2. Strange isn't it?

At least I couldn't find that.

Any other ideas?

Re: VLAN for IOS 12.2(2)T1 ! ?

for example

Int f0/1

no ip address

int f0/1.1

ip address (address and mask)

encapsulation dot1q 1

int f0/1.2

ip address (address and mask)

encapsulation dot1q 2

for vlan1 and vlan2

Keep in mind that dot1Q and ISL encapsulations are only supported on FastEthernet interfaces.

it should be there...

this is an example:

!

ip routing

!

interface fastethernet 4/1.101

encapsulation dot1q 101

ip addr 10.0.0.11 255.0.0.0

this was taken from:

Re: VLAN for IOS 12.2(2)T1 ! ?

Hey guys, the problem was that: there is no "encasulation dot1q" or "encapsulation isl" at all under the (config-subif) mode in FastEthernet, in IOS 12.2(2)T1, but note, that it perfectly works in IOS 12.1(5).

May be this is a bug in this version, or there should be a replacement for these commands.

Please check your IOS 12.2, whether you have it or not.
