show virtual-chassis vc-port diagnostics optics

Syntax

Release Information

Command introduced in Junos OS Release 12.2.

Description

Display diagnostics data and alarms for Ethernet optical transceivers installed in ports configured as Virtual Chassis Ports (VCPs) in an EX Series switches. The information provided by this command is known as digital optical monitoring (DOM) information.

Thresholds that trigger a high alarm, low alarm, high warning, or low warning are set by the transponder vendors. Generally, a high alarm or low alarm indicates that a transceiver is not operating properly. DOM information can be used to diagnose why a transceiver is not working.

On some EX Series switches, the request virtual-chassis vc-port diagnostics optics command must be entered to run a diagnostic scan before you can gather the show virtual-chassis vc-port diagnostics optics output.

Options

none

Display diagnostics information for transceivers installed in VCPs of all members of a Virtual Chassis or VCF.

all-members

(Optional) Display diagnostics information for transceivers installed in VCPs of all members of a Virtual Chassis or VCF.

interface-name

(Optional) Display diagnostics information for the transceiver installed in a specified VCP.

local

(Optional) Display diagnostics information for transceivers installed in VCPs on the switch or external Routing Engine where you enter this command.

member member-id

(Optional) Display diagnostics information for transceivers installed in VCPs on a specified member of a Virtual Chassis or VCF.
