INFINIBAND: "getportcounters" Command to Check If there are Issues/Problems and Errors On 40Gbits/sec Internal Connector Ports of IB Switch (How To Doc)

Below is getportcounters command which can be run on specific 40Gbits/sec IB Switch ports to see if there are any Symbol errors

# getportcounters <internal connector port>

In above command replace internal connector port with the connector port for which you want to check errors. Switch 40Gits/sec connector ports range is from 0A – 15A and 0B – 15B.

We should not be seeing any increase in SymbolErrors gradually or significantly over a period of time when running this command. If there is increase in SymbolErrors then it indicates that there is some issues with connector ports on the IB Switch. It may be lose cabling, bad cable, bad switch port or something else.

As an example if you want check errors on 13B, your command and sample output will look as follows:

# getportcounters 13B
