Port class areas

NOTE

Only State Changes, Packet Loss, and Utilization areas are supported on the VE_Port.

Sync loss The number of times a synchronization error occurs on the port. Two devices

failed to communicate at the same speed. Synchronization errors are always

accompanied by a link failure. Loss of synchronization errors frequently occur due

to a faulty SFP or cable.

Packet loss (VE_Port only) The number of packets routed through a port exceeds the port bandwidth.

PE The number of times a protocol error occurs on a port. Invalid state due to LRR on

an online link. Occasionally these errors occur due to software gliches. Persistent

errors occur due to hardware problems.

RXP The percentage of maximum bandwidth consumed in packet receipts.

ST (Port and VE_Port) The state of the port has changed for one of the following reasons:

• The port has gone offline.

• The port has come online.

• The port is faulty.

TXP The percentage of maximum bandwidth consumed in packet transmissions.

Trunk utilization

(E_Port, FCU_Port, and

FOP_Port)

The percent of utilization for the trunk at the time of the last poll.

Utilization (VE_Port only) The percent of utilization for the trunk at the time of the last poll.

Link reset The ports on which the number of link resets exceed the specified threshold

value.
