Have a 3750 Switch connected to a 3800 series router using fiber. The 3800 series switch is externally managed.
On the switch interface I dont get an LED, plus when I run a "show interface gi 1/0/20" I get the following:
GigabitEthernet1/0/20 is down, line protocol is down (notconnect)
The port is configured similar to as follows:
ip address 192.168.1.1 255.255.255.0
ip route-cache flow
with the router port its connected to being 192.168.1.2/24.
Have switched cables but no difference, cant get the port up and running.
How can I resolve this
