Port class guidelines and default settings
There are different recommendations and default settings for the physical port, the E_Port, and the
FOP_Port and FCU_Port. Refer to the following sections and plan carefully before you begin
configuring the port:
•
•
•
•
NOTE
E_Ports and VE_Ports are not supported in Access Gateway mode.

Port class areas (Continued)
Description
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.
The number of packets routed through a port exceeds the port bandwidth.
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 glitches. Persistent
errors occur due to hardware problems.
The percentage of maximum bandwidth consumed in packet receipts.
The state of the port has changed for one of the following reasons:
•
•
•
The percentage of maximum bandwidth consumed in packet transmissions.
The percent of utilization for the trunk at the time of the last poll.
The percent of utilization for the trunk at the time of the last poll.
The ports on which the number of link resets exceed the specified threshold
value.
