The hardware can manage only a limited number of unique offsets and values. If the switch does
not have enough resources to create a given filter, then other filters may have to be deleted to free
up resources.
Example 1. This command adds a filter-based monitor to count all FCP and IP frames received
from domain 0x02 for port 2.
sw1:admin> perfAddUserMonitor 2, "12, 0xff, 0x05, 0x08; 9, 0xff,
0x02", "FCP/IP"
User monitor #5 added
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 incoming frames where byte 9 is 0x02 and byte 12 is
0x05 or 0x08.
Example 2. The following command adds a special case filter-based monitor for SOFi3 on port 2.
sw1:admin> perfAddUserMonitor 2, "0, 0xff, 6"
User Monitor #6 added

Displaying Filter-Based Monitors

Use the perfShowFilterMonitor command to display all the filter-based monitors of a port. You
can display a cumulative count of the traffic detected by the monitors, or you can display a snapshot
of the traffic at specified intervals.
This command displays all the filter-based monitors defined on the specified port. It displays all the
valid monitor numbers and user-defined aliases on the specified port.
Example 1. The following command displays filter monitor traffic on port 2 at an interval of once
a second. In the command output, "#CMDs" refers to the read, write, and read-write counters, and
"#Frames" refers to SCSI frame, IP frame, and user-defined counters.
