Monitoring ISL Performance
14
Two filter-based monitors are added. The first monitor (#5) counts all FCP and IP frames transmitted
from domain 0x02 for slot 4, port 2. The FCP and IP protocols are selected by monitoring offset 12,
mask 0xff and matching values of 0x05 or 0x08. Domain 2 is selected by monitoring offset 9, mask
0xff, and matching a value of 0x02. The monitor counter is incremented for all outgoing frames from
port 2 where byte 9 is 0x02 and byte 12 is 0x05 or 0x08.
The second monitor (#6) is for SOFi3 on slot 1, port 2.
Deleting Filter-Based Monitors
To delete a filter-based monitor:
1. List the valid monitor numbers by entering the perfShowFilterMonitor command.
2. Enter the perfDelFilterMonitor command to delete a specific monitor. If you do not specify which
monitor number to delete, you are asked if you want to delete all entries.
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,
port 4 using the perfDelFilterMonitor command:
Monitoring ISL Performance
ISL monitoring is set up on E_Ports automatically in release v4.4.0 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 “Displaying
Monitor Counters.” You can clear ISL counters using the perfMonitorClear command, as described in
“Clearing Monitor Counters” on page 14-14.
Monitoring Trunks
For trunked ISLs on Fabric OS v4.x switches, monitoring is set only on the master ISL, which
communicates with the associated slave ISLs. For Fabric OS v3.x switches, monitoring can be set on
slave ISLs.
switch:admin> perfshowfiltermonitor 1/4
There are 4 filter-based monitors defined on port 4.
