Port Duplex

Duplex between two communicating devices specifies whether communication will be one way at a time (half-duplex) or in both directions simultaneously (full-duplex). When auto-negotiation is enabled, auto-negotiation determines port duplex.

Use the set port duplex command to specify whether the specified ports will operate at half or full duplex when auto-negotiation is not enabled.

The following example sets the port duplex on port ge.1.1 to full:

System(rw)->set port duplex ge.1.1 full
System(rw)->show port duplex ge.1.1

default duplex mode is full on port ge.1.1.

System(rw)->
