can not enable tag-switching on the router

[noc]

Good day for all,

i have 7206 g1 router with 7200 Software (C7200-JK9S-M), Version 12.3(4)T4 (enterprise)

and i can not enable mpls.

Router(config)#int gigabitEthernet 0/2.102

Router(config-subif)#mpls ip

% Tag switching not supported on interface GigabitEthernet0/2.102

this error on all interfaces

what is the problem? (cef enable)

Thank You

It must be your software version. I can enable mpls on gig sub interfaces fine. 12.2(18)S5

Do you by any chance have bridging enabled on any of the other sub-interfaces. I have seen this problem in the past with such a configuration.

Hope this helps,

i have no bridging enable on any interface and sub-interface.

as i told before i cant enable tag-switching on any interface

i`ll try change software.

And one of em allows tag-switching on FasteEthernet 0/0.30 (dot1q), other - doesnt :(
