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 https://www.cornet-solutions.co.jp/pdf/mrv_os_900_sdb_a4_hi.pdf

Command Description
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 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
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
