Description

Why does 10 gigabit ethernet (xe) interface show as just gigabit ethernet (ge) interface?

Symptoms

As shown in the configuration and output below, the 10 gigabit ethernet (xe) interface is configured but is not showing up when doing "show interface".

lab@Grug-re0> show configuration interfaces xe-4/0/0
unit 0 {
    family inet {
        address 100.0.0.1/24;
    }
}

lab@Grug-re0> show interfaces xe-4/0/0
error: device xe-4/0/0 not found

Solution

For XENPAK 10 gigabit ethernet interface PICs, ge interface should be used rather than xe interface for configuration.
