Status of Interfaces

From the Command Line Interface, the current status of the Ethernet (eth1)

Interface and the DSL (dsl1) Interface can be obtained with one command:

show interface

The information displayed for Ethernet and DSL Interfaces is presented below.

show interface {eth1 dsl1}

Use to request status statistics for the named interface, eth1 or dsl1.

Minimum access level: Operator

eth1 ± Ethernet interface

dsl1 ± DSL interface

eth1 status ± Fields included in the display of Ethernet status: eth1

±Ethernet Link: { up down }

This is the same status as reflected by the Ethernet LED.

±MAC address: xx:xx:xx:xx:xx:xx

±proxy ARP eth1 { enabled disabled }

±ifn eth1:1 ± ip-addr x.x.x.x mask x.x.x.x *

±ifn eth1:2 ± ip-addr x.x.x.x mask x.x.x.x

±ifn eth1:3 ± ip-addr x.x.x.x mask x.x.x.x

±ifn eth1:4 ± ip-addr x.x.x.x mask x.x.x.x

dsl1 status ± Fields included in the display of DSL status: dsl1

±DSL Link: { up down }

This is the same status as reflected by the DSL LED.

±MAC address: xx:xx:xx:xx:xx:xx

±proxy ARP dsl1 { enabled disabled }

±ifn dsl1:1 ± ip-addr x.x.x.x mask x.x.x.x *

±ifn dsl1:2 ± ip-addr x.x.x.x mask x.x.x.x

±ifn dsl1:3 ± ip-addr x.x.x.x mask x.x.x.x

±ifn dsl1:4 ± ip-addr x.x.x.x mask x.x.x.x

*The Primary designation of a numbered interface marks that interface as the one whose IP address is used as a Router ID. If no interface is defined as Primary, the last numbered interface created becomes the Primary IP Address.
