Layer 2:
Lock: Shows the lock status of the link:
OK: The 10G Ethernet Phy Rx port is successfully locked to the
inbound Ethernet signal.
ERROR: The 10G Ethernet Phy Rx port lost lock to the incoming
Ethernet signal during the last second. This indicates there is likely a
physical layer problem with the link.
CRC Error columns:
STATUS: There have been no overflow errors in the Ethernet MAC
during the last second.
ERR SECS: An errored second is an interval of a second during which
any error has occurred, regardless of whether that error was a single
bit error, or a complete loss of communication for that entire second.
Layer 2 Metrics
Rx Bytes: A count of the number of bytes received.
Rx BER High: Indicates that the Sync Header BER is greater than 10^-4.
Rx CRC Errors: A count of the number of CRC errors detected.
Rx Frames Ok: A count of the number of Ethernet frames received
without error.
Rx Frames Errored: A count of the number of Ethernet frames received
with errors detected.
Rx Undersize Packets: A count of the number of Ethernet frames
received that are less than 64 bytes long.
Rx Oversize Packets: A count of the number of Ethernet frames received
that are greater than 1522 bytes long.
Tx Bytes: A count of the number of bytes transmitted.
Tx Frames Ok : A count of the number of Ethernet frames transmitted
without error.
Tx Frames Errored: A count of the number of Ethernet frames
transmitted with errors detected.
