282 ExtremeWare 7.7 Command Reference Guide
Commands for Configuring Slots and Ports on a Switch
configure ports preferred-medium
configure ports <nnn> preferred-medium {copper} | {fiber} |[force]
Description
Configures the primary uplink port to use a preferred medium.
NOTE
This command is available only on the Summit 300-24 and Summit 400-48t switches.
Syntax Description
Default
The default is determined at cable installation time.
Usage Guidelines
By specifying either copper or fiber, the switch starts the assignment with that medium and uses this
preferred medium the next time the switch is rebooted. However, when a failure occurs and the uplinks
are swapped, the switch continues to keep that uplink assignment until another failure occurs or until
the assignment is changed using the CLI. To require that the switch revert to the preferred-medium, use
the force option.
Examples
The following Summit 400-48t example establishes port 4 as the primary uplink and port 4X as the
redundant uplink port:
configure ports 4 preferred-medium copper
Port 4 becomes the primary uplink until a failure occurs on that link. At that time, port 4X becomes the
primary uplink and port 4 becomes the redundant port. This assignment stays in place until the next
failure.
The following example forces the switch to use the fiber port whenever it has a link:
configure ports 3 preferred-medium fiber force
In this example, port 3X becomes the primary uplink port until a failure occurs on the link. At that time,
port 3 becomes the primary uplink and port 3X becomes the redundant port. When port 3X
re-establishes the link, port 3X becomes the primary uplink port again.
nnn Specifies the port number. Valid port numbers are 1X to 4X for fiber and ports 1 to 4 for copper.
copper Specifies that the switch should always use the 10/100/1000 connection whenever a link is
established, regardless whether a fiber link is also present.
fiber Specifies that the switch should always use the 1 Gigabit fiber connection whenever a link is
established, regardless whether a copper link is also present.
force Forces the switch to switchover to the selected media type immediately (if it has link). NOTE: This
option is not available on the Summit 300-24.
