Monitoring Isl Performance; Monitoring Trunks; Displaying Monitor Counters - HP A7533A - Brocade 4Gb SAN Switch Base User Manual

The following example displays the monitors on slot 1, port 4 using the perfShowFilterMonitor
command (the monitor numbers are listed in the KEY column) and deletes monitor number 1 on slot 1:
switch:admin> perfshowfiltermonitor 1/4
There are 4 filter-based monitors defined on port 4.

The specified filter-based monitor is deleted.

Monitoring ISL performance

ISL monitoring is set up on E_Ports in release 4.4.0 and later.
An ISL monitor measures traffic to all reachable destination domains for an ISL, showing which destination
domain is consuming the most traffic. If there are more than 16 domains, the monitor samples traffic and
extrapolates the measurement.
You can monitor ISL performance using the perfMonitorShow command, as described in
monitor counters" on page 207." You can clear ISL counters using the perfMonitorClear command,
as described in

Monitoring trunks

For trunked ISLs on Fabric OS 4.x switches, monitoring is set only on the master ISL, which communicates
with the associated slave ISLs. For Fabric OS 3.x switches, monitoring can be set on slave ISLs.
EE monitors are not supported for ISLs.
The SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, Core Switch 2/64, SAN Director
2/128, and 4/256 SAN Director support eight filter-based monitors for trunks.
The 4/8 SAN Switch, 4/16 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, and
SAN Switch 4/32 support 12 filter-based monitors for trunks.

Displaying monitor counters

Use the perfMonitorShow command to display the monitors on a specified port. For EE counters, you
can display either the cumulative count of the traffic detected by the monitors or a snapshot of the traffic at
specified intervals.
NOTE: The 4/8 SAN Switch, 4/16 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class
BladeSystem, and SAN Switch 4/32 outputs do not include CRC counts.
