I am connecting a new switch to our Core Switch with a single Fiber / Mini GBIC / LC Connectors.
I can see the uplink is live on the ports and show int shows that there is broadcast traffic pinging around.
I have given the DEFAULT VLAN an ip and ip default gateway.
On the Core switch the 4 x Modules are trunked, i trunked the 4 x modules on the new switch (Although only one module is in place)
I cannot seem to connect the switch to our network or ping the new one.
If i only have one Fiber Uplink is a trunk needed?
