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 (0x1 1), switch area ID 30 (0x1e), AL_PA 0xef on
Switch Y.

Setting end-to-end monitors on a port

End-to-end performance monitoring looks at traffic on SID/DID pairs in any direction. 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 0x1 1 1eef 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 0x1 1 1eef. 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 0x1 1 1eef 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 0x1 1 1eef 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.
