Sample Cisco Catalyst switch configuration
Any Cisco POE Switch: On the connecting interface/port, issue the command ‘Power inline
static 10000’.
2900/3500-series:
1. On the connecting interface/port, issue the command ‘spanning-tree portfast’, which will
greatly reduce the time STP is performed on the interface/port.
2. If you are using a 2950 or 3550 switch, issue the command ‘switchport mode access’ to
disable trunking on the interface/port.
3. On the connecting interface, issue the commands ‘speed 100’ (or ‘speed 10’) and ‘duplex
full’ (or ‘duplex half’) to lock the speed and duplex of the port.
2948/2980/4000/4500/5000/5500/6500-series running CatOS:
1. On the connecting interface/port, issue the command ‘set spantree portfast __/__ enable’
(fill in first blank with module number, and second blank with port), which will greatly reduce
the time STP is performed on the interface/port.
2. On the connecting interface/port, issue the command ‘set port channel __/__ off’ (fill in first
blank with module number, and second blank with port range), which will disable
EtherChannel (PAgP) on the interface/port.
3. On the connecting interface/port, issue the command ‘set port trunk __/__’ (fill in first blank
with module number, and second blank with port), which will disable trunking on the
interface/port.
4. On the connecting interface/port, issue the command ‘set port speed __/__ 100’ (fill in first
blank with module number, and second blank with port), which will lock the speed to
100Mbps on the interface/port (you can also lock it to 10Mbps if you wish).
5. On the connecting interface/port, issue the command ‘set port duplex __/__ full’ (fill in first
blank with module number, and second blank with port), which will lock the duplex to full on
the interface/port (you can also lock it to half duplex if you wish).
Note Cisco switches running CatOS 5.2 and newer have a special macro command called ‘set
port host __/__‘ that sets the interface/port for portfast, disables trunking, and disables
EtherChannel. You will still have to manually set the speed/duplex for the port(s), however.
1900-Series
1900-series switch have portfast enabled by default on the 10mbps ports and disabled on the
100 Mbps ports. If you are using the 100mbps ports to connect to a SonicWALL device, issue
the command ‘spantree start-forwarding’, which will greatly reduce the time STP is performed
on the interface/port.
Sample Dell switch configuration (per interface)
• spanning-tree portfast
• no back-pressure
• no channel-group
• duplex half (note: only if you are seeing FCS errors)
• speed 100
• no flowcontrol
• no gvrp enable
