Hello,
I'm using a Cisco 1720 with 12.2(2) IOS
And the following command on the subinterface give an error:
encapsulation dot1q 1
Encapsulation command is available but with no parameters and it's not accepted alone.
Is there any way to so that?
Regards,
Omar

Hi
try with the native keyword and check.
Thanks

Once I use '?' the encapsulation exists but:
encapsulation ?
gives me that the command is incorrect.

could you try upgrading from 12.2 to a newer IOS?

The only available RAM and Flash permitted me to go through 12.3(18)a
And the same problem I'm encountering.

Hi:
You need the IP PLUS image at least to set encapsulation protocols on a 1720.

Hi,
Can this be the cause -
IEEE 802.1Q VLAN Routing - No on 1720 router -
