part of a filter definition. Offset 0 is a special case, which can be used to monitor the first 4 bytes of the 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 80. Table 80 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. Adding custom filter-based monitors 1. Connect to the switch and log in as admin. 2. Enter the perfaddusermonitor command: perfaddusermonitor [slotnumber/]portnumber "grouplist" [ alias ] where: slotnumber portnumber grouplist alias For bladed systems only, specifies the slot number of the port on which the monitor is to be added. For all other switches, this operand is not required. Specifies the port number Specifies up to six sets of offset, mask, and value An optional name for the monitor 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 1. Connect to the switch and log in as admin. 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 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. Fabric OS 6.2 administrator guide 413
