LAB: SPEED & DUPLEX Speed and Duplex Settings *The devices auto-sensed their current settings *We will force them to specific speed/duplex View interface details 1. #show interface Ethernet interface speed/duplex must match 2. *note the speed and duplex settings 3. #show interface status (switches only) Most NICs can auto-sense (speed auto, duplex auto) Switch 0 G0/1 – force the speed and duplex Still a common problem (mismatched speed/duplex) 1. (config)#interface g0/1 2. (config-if)#speed 1000 3. (config-if)#duplex full Switch 1 G0/1 – force the speed and duplex 1. (config-if)#interface g0/1 Packet Tracer Lab File: 2. (config-if)#speed 1000 3. (config-if)#duplex full Switch 0 G0/1 – force a mismatch “Speed & Duplex.pkt” 1. (config-if)#duplex half 2. *note the connection goes down 3. (config-if)#duplex full 4. *note the connection comes back up 5. (config-if)#speed 100 6. *note the connection goes back down 7. (config-if)#speed 1000 8. *note the connection comes back online
