Vlan encapsulation issue

I'm going to use Metro-Ethernet with fast ethenet port on 4ESW in 2851XM router.

Because the port can not work as L3, I set VLAN. But far end device is not Cisco. I need to dot1q for this connection but I can't.

How can I enable dot1q encapsulation for VLAN?

Re: Vlan encapsulation issue

at the trunk links you can set the encapsulation to 802.1q.

I hope that i got your point!

Hi Winqu,

Try this... it should work.

Config sample

!

configure terminal

!

interface fastethernet 2/3

shutdown

switchport trunk encapsulation dot1q

switchport mode trunk

no shutdown

exit

!

Verify:

show interfaces fastethernet 2/3 switchport

show interfaces fastethernet 2/3 trunk
