Enabling or Disabling Ports
Disabling ports turns off their receivers and transmitters so that they
cannot forward traffic. You might disable unused ports on the switch to
protect them from unauthorized use, or if there is a problem with a cable or
a network device.
To disable ports, use the SHUTDOWN command in the Port Interface
mode. To enable ports again, use the NO SHUTDOWN command.
This example disables ports 1 to 4:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.1-port1.0.4
awplus(config-if)# shutdown
This example enables ports 17 and 22:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.17,port1.0.22
awplus(config-if)# no shutdown
For reference information, refer to “SHUTDOWN” on page 250 and “NO
SHUTDOWN” on page 224.
