This is an old revision of the document!
These items will probably get their own pages at one point.
Uses V.35 connector!
Good things to know:
Switch(config)#interface range fastEthernet 0/1-5, fastEthernet 0/10-15
Switch#clear port-security all
Default switchport mode appears to be dynamic auto.
Speed and Duplex are auto-negotiated by default. These commands also work on routers. Manually configure them with:
Switch(config-if)#speed ? 10 Force 10 Mbps operation 100 Force 100 Mbps operation auto Enable AUTO speed configuration Switch(config-if)#duplex ? auto Enable AUTO duplex configuration full Force full duplex operation half Force half-duplex operation
Re-enable auto-negotiation by removing the configured speed/duplex:
Switch(config-if)#no duplex Switch(config-if)#no speed
I'll update these as I come across them.
