Thank you for posting this question in the Support Community. To disable and re-enable a switchport on the NetVanta 1238 you will issue the shutdown followed by the no shutdown commands. For example:
ROUTER-NAME# configure terminal
ROUTER-NAME(config)# interface switchport 0/1
ROUTER-NAME(config-swx 0/1)# shutdown
ROUTER-NAME(config-swx 0/1)# no shutdown
