TABLE 15
Area
Description
Signal loss
The number of times that a signal loss occurs in a port. Signal loss indicates that no
data is moving through the port. A loss of signal usually indicates a hardware
problem.
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.
Protocol errors (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 glitches. Persistent
errors occur due to hardware problems.
Received packets (RXP)
The percentage of maximum bandwidth consumed in packet receipts.
State changes (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.
Transmitted packets (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.
NOTE
Only the Packet loss, State changes, and Utilization areas are supported on the VE_Port.
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:
•
Physical port setting guidelines
on page 67
•
E_Port subclass setting guidelines
on page 71
•
FOP_Port and FCU_Port subclass setting guidelines
on page 74
•
VE_Port class default settings
NOTE
E_Ports and VE_Ports are not supported in Access Gateway mode.
