Configuring Interface Preference on a Dual-Interface Gigabit
Ethernet Port (WSS-400 only)
The gigabit Ethernet ports on an WSS-2380 switch have two physical interfaces: a 1000BASE-TX copper
interface and a 1000BASE-SX or 1000BASE-LX fiber interface. The copper interface is provided by a built-in
RJ-45 connector. The fiber interface is optional and requires insertion of a Gigabit interface converter (GBIC).
Only one interface can be active on a port. By default, WSS Software prefers the GBIC (fiber) interface. You
can configure a port to prefer the RJ-45 (copper) interface instead.
If you set the preference to RJ-45 on a port that already has an active fiber link, WSS Software immediately
changes the link to the copper interface.
To configure a port to prefer the copper interface, use the following command:
set port preference port-list rj45
To remove the preference setting from a port so that GBIC (fiber) is preferred again, use the following
command:
clear port preference port-list
To display preference settings, use the following command:
show port preference [port-list]
To set the preference of port 2 on an WSS-2380 switch to copper and verify the change, type the following
commands:
WSS-2380# set port preference 2 rj45
WSS-2380# show port preference
