Congestion:
Port Transmit Discards (neighbor port)
Port Transmit Congestion (neighbor port)
Port Transmit Wait (neighbor port)
SmaCongestion:
VL15 Dropped Errors
Security:

Port Transmit Constraint Errors (neighbor port)
Routing:
Port Receive Switch Relay Errors
For each error subgroup five error 'buckets', from 0+% to 100+% in 25%
increments, count the number of ports whose 'error compared to error threshold'
value corresponds to that bucket. This provides an indication of how error rates
compare to their thresholds.
In addition, to aid analysis of congestion, the raw values for maximum
Congestion, Transmit Discards, Inefficiency, and number of Adaptive Routing
adjustments are shown.
The Error Statistics screen accepts input commands which specify parameters to
be used in a group focus query, which will provide a list of ports sorted according
to a specified error criterion. The second line of the Error Statistics screen displays
the group name, and the currently selected focus criterion and number of ports for
a group focus query. The D command causes the group focus query to be
performed and displayed in a Group Focus screen. The following input commands
are accepted in the Error Statistics screen.
C: Select group focus criterion forward (c*) or reverse (C*):
Integrity errors (highest first)
Congestion errors (highest first)
SmaCongestion errors (highest first)
Security errors (highest first)
Routing errors (highest first)
Adaptive routing (highest first)
Nn: Number of entries n in group focus list
D: Display detail group focus list
