Hi All,

Good Day!

Just want to ask again for your help.

I'am configuring Cisco 2801 but when I command the interface Vlan the ord vlan is not recognize.

Is there any missing command?

Please help!

Hello,

On 2801 routers, the interface Vlan command would be accepted only if you had a switching module, such as EHWIC-4ESW, installed in the router.

If you want to use VLANs on your physical Fa0/0 and Fa0/1 ports, you simply create subinterfaces like this:

interface FastEthernet0/0
 no shutdown ! Do not forget to activate the interface
!
interface FastEthernet0/0.11 ! The number .11 is arbitrary - from 1 upwards, not related to VLAN ID
 encapsulation dot1q 11 ! This is the VLAN ID this subinterface is created for
 ip address ...

Best regards,

Peter
