Layer 2:
o
Lock
: Shows the lock status of the link:
§
OK
: The 10/25G Ethernet Phy Rx port is successfully
locked to the inbound Ethernet signal.
§
ERROR
: The 10/25G 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.
o
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
o
Rx Bytes
: A count of the number of bytes received.
o
Rx BER High
: Indicates that the Sync Header BER is greater than
