Issue/Introduction

Presents example output of the show interface detail command

Cause

The show interface detail command displays the current state for a physical interface. If no interface is specified, status is displayed for all physical interfaces. The detail parameter displays verbose information, and allows you to specify additional parameters to filter the verbose output to display only data for the physical line, IPv4, IPv6, or non-IPv4 frame types, interface type, or to display data for a specific interface. The IP frame type parameters apply only to NPM interfaces.

With the exception of management interfaces, the MTU setting is defined at the circuit level. Use show circuit to display the MTU.

Besides many other details, it shows rates per minute for displayed counters allowing you to better understand traffic being processed at the time of command execution.

Below is presented example output for one of interfaces:

# show interface detail
Gigabitethernet 1/1 is up
  Interface is not in use
  Hardware address is N/A
  SFP info:
    phy_present|phy_good
    Media Type: Copper, Vendor Name: Molex Inc.      
  MTU N/A, BW 1 Gigabit, full-duplex, auto-negotiation is enabled
