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.

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?

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

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.
