configuration problem or ios "feature"?

Hi there,

today i started some MPLS researches, however my problem is not concerned to MPLS. I start to configure one of our lab routers (you can find more information about it bellow) and i get this error:

cr1.SOF1(config)#int gi 3/39.100

cr1.SOF1(config-subif)#encapsulation dot1Q 100


cr1.SOF1(config-subif)#int gi3/38.100

cr1.SOF1(config-subif)#encapsulation dot1Q 100

Command rejected: VLAN 100 not available

So i'm wondering is there any global config command to support this feature or what? I decided to try the SRB modification of this IOS but i have not had time to test it yet. So if anyone of you guys have an idea, please tell . I'll appreciate your help!!

Thanks in advance!

Kind Regards,

Danail Petrov


Re: configuration problem or ios "feature"?

Hi Danail

This is normal behavior with any of the boxes we did try the same in some of our boxes (ME 6524) and went on with some workaround for the same..
