Configure Ports Preferred-Medium - Extreme Networks ExtremeWare XOS Command Reference Manual

configure ports preferred-medium

configure ports <port_list> preferred-medium [copper | fiber] {force}
Description
Configures the primary uplink port to use a preferred medium.
Syntax Description
port_list Specifies the port number. Valid port numbers are 1 to 4.
copper Specifies that the switch should always use the 10/100/1000 BASE-T connection
whenever a link is established even when a fiber link is also present.
fiber Specifies that the switch should always use the 1 gigabit Ethernet fiber connection
whenever a link is established even when a copper link is also present.
force Disables automatic failover. (If the specified preferred medium is not present, the link
does not come up even if the secondary medium is present.)
Default
The default is determined at cable installation time.
Usage Guidelines
You specify either
copper
time the combo ports come online. If both are present, the configured preferred medium is chosen;
however, if only one is present, the switch brings up that medium and uses this medium the next time
the switch is rebooted. 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.
If you use the option, it disables automatic failover. If you force the preferred-medium to fiber
force
and the fiber link goes away, the copper link is not used, even if available.
Examples
The following establishes copper port 4 as the primary uplink and fiber port 4 as the redundant uplink
port:
configure ports 4 preferred-medium copper
Copper port 4 becomes the primary uplink until a failure occurs on that link. At that time, fiber port 4
becomes the primary uplink and copper port 4 becomes the redundant port. This assignment stays in
place until the next failure.
