where: slotnumber portnumber sourceID destID 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 the 3-byte SID (source ID) of the originator device Specifies the 3-byte DID (destination ID) of the destination device Figure 71 shows two devices: • Host A is connected to domain 5 (0x05), switch area ID 18 (0x12), AL_PA 0x00 on Switch X. • Dev B is a storage device connected to domain 17 (0x11), switch area ID 30 (0x1e), AL_PA 0xef on Switch Y.

That is, even if the SID is for a remote device, the traffic is monitored in both directions (the Tx/Rx counters are reversed). Monitoring the traffic from Host A to Dev B Add Monitor 0 to slot 2, port 2 on Switch x, specifying 0x051200 as the SID and 0x111eef as the DID, as shown in the following example: switch:admin> perfaddeemonitor 2/2, "0x051200" "0x111eef" End-to-End monitor number 0 added. Monitor 0 counts the frames that have an SID of 0x051200 and a DID of 0x111eef. For monitor 0, RX_COUNT is the number of words from Host A to Dev B, and TX_COUNT is the number of words from Dev B to Host A. Monitoring the traffic from Dev B to Host A Add Monitor 1 to slot 2, port 14 on Switch y, specifying 0x111eef as the SID and 0x051200 as the DID, as shown in the following example. switch:admin> perfaddeemonitor 2/14, "0x111eef" "0x051200" End-to-End monitor number 1 added. Monitor 1 counts the frames that have an SID of 0x111eef and a DID of 0x051200. For monitor 1, RX_COUNT is the number of words from Dev B to Host A, and TX_COUNT is the number of words from Host A to Dev B. Figure 72 shows several switches and the correct ports on which to add performance monitors for a specified SID-DID pair. SID 0x051200 Add monitors here Host . . . . . . . . . . . .
