Hi,
I have a 3825 that I am trying to connect to a 3508 Switch via 1000BASE-SX. I have an SFP in Gi0/0 of the router and a 1000BASE-SX model in Gi0/8 of the switch. Both the switch and the router can see each other when using the "show cdp neighbors" command. As a side note, I also have a NMD-36-ESW (36 port switch) in the router which is functioning normally. When connecting to that 36 port switch, I get an IP and traffic flows normally.
I've tried creating a subinterface on the 3825 and enabling a dotq encapsulation, but I do not get any connectivity. I cannot ping the router from the switch, or vice versa.
I've included my running configs below. Any help would be greatly appreciated.
Thanks!
