REQ - Help with config of 2950

You can use the port security feature to restrict the devices that can be connected to a port by MAC addresses. Here is an example:

Switch(config)#interface fastethernet0/2 Switch(config-if)#switchport mode access Switch(config-if)#switchport port-security Switch(config-if)#switchport port-security mac-address 0422.1043.0a31 Switch(config-if)#exit

The following papers explain the details about port security configuration:

Mark,

Read the answer to your questions below.

Question 1

If you're hardware supports it you can use Auto-MDIX setting. This will sense the cabling used either straight-through or crossover.

switch#configure terminal switch(config)#interface fastethernet 0/1 switch(config-if)#mdix auto switch(config-if)#end switch#

Question 2

switch#configure terminal switch(config)#interface fastethernet 0/1 switch(config-if)#switchport mode access switch(config-if)#switchport port-security switch(config-if)#switchport port-security mac-address 0001.0002.0003 switch(config-if)#end switch#

That wasn't hard now was it? Try Googling for answers next time! It's all there.

Don't forget to save your configuration!
