Allied Telesis Essential Switch Commands and Default IP Settings for Effective Management

64 AT-8800 Series Switch User Guide

To enable or disable a switch port, use the commands:

ENABLE SWITCH PORT={port-listALL}

DISABLE SWITCH PORT={port-listALL}

Resetting Ethernet ports at the hardware level discards all frames queued for reception or transmission on the port, and restarts autonegotiation of port speed and duplex mode. Ports are reset using the command:

RESET SWITCH PORT={port-listALL} [COUNTER]

To display information about switch ports, use the command:

SHOW SWITCH PORT[={port-listALL}]
