I?m replacing a 2621 with VWIC-2MFT-T1 cards and going to a 2821 with VWIC2-2MFT-T1/E1 cards.
When I do the cut-over all of my serial interfaces are showing up, line protocol is down.
All of my existing routers have the older vwic-2mft-t1 cards. My new configuration is a copy of my old 2621 config, so I don?t see where the problem lies.
I?d like to try swapping out the router again this weekend, but I?m not sure what is causing the protocol to be down. Any ideas?
