[c-nsp] Command default interface Gix/y

[Rin]

Hi group, 

 

Below is a weird problem when I set an interface on ES20 linecard to its
default setting 

Router(config)#default int g3/0/1   

Command rejected: not allowed on this interface.

Command rejected: not allowed on this interface.

Command rejected: not allowed on this interface.

% Error(s) seen setting interface GigabitEthernet3/0/1 to it's default
config

 

The router is 7609 and use 12.2(33)SRD. The command can be applied normally
on other interface on the same card. Anyone has any idea?

 

Thanks,

 

Rin
