INFINIBAND: "getportcounters" Command to Check If there are Issues/Problems and Errors On 10Gbits/sec ETH Ethernet Connector Ports of IB Switch (How To Doc)

Below are getportcounters commands which can be run on 0A-ETH and 1A-ETH Ethernet Connector ports of IB Switch to check if there are an RX, TX and CRC errors

# getportcounters 0a-eth | egrep -i "error|CRC"
# getportcounters 1a-eth | egrep -i "error|CRC"

Below is example snippet of above command.

# getportcounters 0a-eth | egrep -i "error|CRC"
RX CRC...........................0
RX errors........................0
TX errors........................0
RX CRC...........................0
RX errors........................0
TX errors........................0
RX CRC...........................0
RX errors........................0
TX errors........................0
RX CRC...........................0
RX errors........................0
TX errors........................0

If we see any gradual or significant increase of RX/TX errors and RX CRC errors over a period of time, then it indicates that there is some issues with 0A/1A ETH connector ports on the IB Switch. It may be lose cabling, bad cable, bad switch port or something else.
