frame (SOF). When the offset is set to 0, the values 0-7 that are checked against that offset are predefined as shown in Table 74. Table 74 Predefined values at offset 0 Value SOF Value SOF 0 SOFf 4 SOFi2 1 SOFc1 5 SOFn2 2 SOFi1 6 SOFi3 3 SOFn1 7 SOFn3 If the switch does not have enough resources to create a given filter, other filters might have to be deleted to free resources. The following example adds filter-based monitors: switch:admin> perfaddusermonitor 4/2, "12, 0xff, 0x05, 0x08; 9, 0xff, 0x02" "FCP/IP" User monitor #5 added switch:admin> perfaddusermonitor 1/2, "0, 0xff, 6" User Monitor #6 added 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. Issue the perfDelFilterMonitor command to delete a specific monitor. 2. If you do not specify which monitor number to delete, you are asked whether you want to delete all entries. The following example deletes monitor number 1 on slot 1, port 4 using the perfDelFilterMonitor command: switch:admin> perfdelfiltermonitor 1/4, 1 The specified filter-based monitor is deleted. ISL performance monitoring ISL monitoring is set up on E_Ports automatically 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. EE monitors on E_Ports are deleted when they become part of an ISL. ISL monitors are deleted when Top Talker is installed and are restored when Top Talker is deleted. (See "Top Talker monitors" for information about Top Talker monitors.) 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 356. ISL monitoring is not supported on the DC Director.
