To apply the authentication type, use the following command:
CAT5KRSM(config)# ip http authentication local
Note To disable the configured authentication type, use the no ip authentication command.
To configure the username hsn with the password team, use the following command:
CAT5KRSM(config)# username hsn password team
You can provide an additional layer of protection when using Cisco's IOS ClickStart software or the Cisco
Web browser interface. To do so, change the default TCP access port 80 to port 50, or any port you plan to
use. To set the TCP port to 50, use the following command:
CAT5KRSM(config)# ip http port 50
You can reset the HTTP TCP port to its default by using the following command:
CAT5KRSM(config)# no ip http 50

To show a port configuration for port security, use the following show command:
CAT5K> (enable) show port 3/3
