To define a custom filter, use the perfAddUserMonitor command. With this command, you must specify a series of offsets, masks, and values. For all transmitted frames, the switch performs these tasks: • Locates the byte found in the frame at the specified offset. • Applies the mask to the byte found in the frame. • Compares the value with the given values in the perfAddUserMonitor command. • Increments the filter counter if a match is found. The following number of offsets can be specified: NOTE: Bloom-based switches provide 2 unique unused offsets per port for user-defined filter monitors other than the 6 offsets already reserved for pre-defined filter monitors. Condor-based switches provide 15 unused offsets per port. To illustrate, if you were to enter: perfaddusermonitor 30 "4, 0xff, 0x06; 6, 0xff, 0x02; 7, 0xff, 0xd4" The operation would be successful because offset 4 is a canned monitor and has a resource already reserved for it. Offsets 6 and 7 would exhaust all unique filter monitor resources on port 30. Therefore, any additional filter monitors created on port 30 would have to be canned filter monitors. • SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32 and SAN Director 2/128 models (Fabric OS v4.0.0 or later) Up to two different offsets per port (one offset when FICON management server mode (FMS) is enabled). • 4/64 SAN Switch, 400 MP Router and 4/256 SAN Director model (Fabric OS 5.1.0b minimum) Up to 15 different offsets per port (14 offsets when fmsmode is enabled). • HP StorageWorks SAN Switch 2/8 EL, SAN Switch 2/16 (Fabric OS v3.0.0 or later) Up to three different offsets per port. • SAN Switch 4/32 model (Fabric OS v4.4.0 or later) Up to 15 different offsets per port (14 offsets when FMS is enabled). 318 Administering Advanced Performance Monitoring (APM)
