Cisco 4321 sub interface

toby

Level 1

Hello all;

I am trying to move a config from an old 1841 router to our new 4321 and am have issues with all my sub interfaces communicating. See attach for the config with ip changes of course. the 0/0/1.1 sub interface is communicating fine but nothing else in this building will communicate even to other devices in the building. I am hoping it is just a command I forgot between the old and new software versions. Any help is greatly appreciated.

Thanks

That looks fine.  Perhaps try adding "ip routing" to make sure routing is enabled.

I assume the old router was using 802.1q trunking as well?  I assume you are plugging the new router into the same ports on the router as the old router?

Yes to all of your questions. The strange thing is that anything on the GigabitEthernet0/0/1.1 is working the rest are not. I will try your suggestion and possibly boot the switch at the same time to see if it makes any difference.  Thank you for your help
