MRV Optiswitch OS904 OS906 OS912 debug and diagnostic commands


MRV Communications (acquired in 2017 by ADVA Optical Networking) is an Israeli company known for their optical network equipment, most notably their Optiswitch Carrier Ethernet Switch series. The switches (OS904, OS906G, OS912) are not available for purchase from them anymore, but if you work for a telco company, you surely still have these boxes around doing their work.

Unfortunately, with the merger and the end of sale, all the documentation disappeared as well. To help you a bit I bring below some debug and diagnostic commands to be run on the CLI. You can still find the datasheet here www.cornet-solutions.co.jp/pdf/mrv_os_900_sdb_a4_hi.pdf

Command Description

no cli-paging/cli-paging

Enable/disable paging the output.

show <smth> | <include/begin/end/exclude> <search term>

Pipe output of some show command, e.g. find specific MAC address: show lt | include B1:12 (search terms are case sensitive). Also can pipe to few Linux commands, e.g. count number of learned/dynamic MACs: show lt | grep -c "DYNAMIC"

show run

Show the running configuration

show port

Show port summary: state (on/off), speed, media (copper/sfp), duplex state

show interface

List of logical/vlan interfaces, MAC addresses, IP address (if any)

show port detail n

Show details of the port number n: media type, speed/duplex configured and actual, state, shaping applied.

show port statistics n

Show real-time statistics: packets/bytes received/sent, CRC and other error count

show l2cntrl-protocol-counters

Show counters of received/transmitted Layer 2 control protocols - LACP, MSTP, RSTP, OAM.

show run ports

Show running configuration for all ports

show port tag

Show tagging/vlans configured on each port

show port sfp-diag n

Show real-time diagnostic data for the interface: TX/RX power in dBm, voltage, temperature

show port sfp-params

Physical parameters of the SFP interface

show port rate portnumber time seconds

Show the rate of the traffic passing the interface real-time

monitor port statistics portnumber

Show the same data as show port statistics but refresh every other second

(config)# port state disable/enable portnumber

Disable/enable MRV port number portnumber (shut/no shut in Cisco terminology). Make sure you don’t disable th eport you are connected through.

(config)# port media-select <sfp/sfp100/copper/auto/sgmii>

Set manually type of physical interface installed in MRV.

(config)# port speed <10/100/1000/auto> <portnumber/all>

Force specific speed settting for a port.

show lt [port <portnumber> tag all]

Show MAC address table - static and learned dynamic. Output also gives timestamp when MAC address displayed was last changed. Optionally, specify port to show only MACs on this port.

(config)# clear lt

Delete all learned MAC addresses from Learning Table.

show syslog <all/debug/info/warning/error/fatal> [start-date] [end-date]

Show logs per their severity. Optional start/end dates are in format mm-dd-ff:mm:ss . If remote syslog is configured in the MRV, there will be NO local logs, to verify - look in configuration show run | i rsyslog.

clear syslog

Delete all local log entries.

show ver

Show the device model, hardware, fan status, OS installed, MAC address, serial number and uptime.

show time

Show system time. Important for checking alarms and logs

show cpu

CPU properties

Examples

show syslog info
