`show interfaces`

Syntax

show interfaces [brief | config | <PORT-LIST>]

Description

Shows interface information for ports or trunk groups in brief or configuration detail.

Command context

operator or manager

Parameters

brief

Shows the current operating status for all ports or trunk groups on the switch in brief detail.

config

Shows the configuration data for all ports or trunk groups on the switch.

<PORT-LIST>

Specifies the list of ports for which status information will be shown.

<TRUNK-GROUP>

Specifies the trunk group for which status information will be shown. The status information shown consists of total transmit and receive counters and weighted average rate for the trunk group specified. The weighted average rate is calculated in 5 minute intervals.

Usage

Both external and internal ports are supported on the same module. Internal ports have an “I” suffix in the output of the show command to indicate that they are internal ports.

“10GbE-INT” – Internal 10G data-plane ports (1i-2i, 4i-5i)
“1GbE-INT” – Internal 1G control-plane port (3i)
Port 3i always shows as link-down.

Examples
