I am in the process of connecting a Netgear FSM726 to a Cisco Switch. When I do this, with auto/auto on the Switch end, it keeps coming up as err-disabled.
I have done the following:
1. Removed spantree portfast.
2. Change the port to 100/Full
3. Moved the ports on the Netgear and Cisco Switch around
But it still err-disables the port.
