Greetings Cisco Experts,
I’m trying to connect two Cisco 3660 back-back using VWIC-2MFT-E1 (RJ 48 cross over)
Cisco 3660(VWIC-2MFT-E1)=====(VWIC-2MFT-E1)Cisco3660
One of the VWIC-2MFT-E1 is in the 2W slot and the other is in the 2FE-2W slot
But for some reasons both of them are not talking to each other and I’m getting
A lot of slip alarms on the controllers
Following is the simple config of both routers
Router 1
controller E1 5/0
