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.
Figure 5
Setting end-to-end monitors on a port
NOTE:
End-to-end performance monitoring looks at traffic on the receiving port respective to the SID
only. In
, if you add a monitor to slot 2, port 2 on Switch X, specifying Dev B as the SID and Host
A as the DID, no counters (except CRC) are incremented.
To monitor 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:
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, TX_COUNT is the number of words from Dev B
to Host A, and CRC_COUNT is the number of frames in both directions with CRC errors.
To monitor 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.
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, TX_COUNT is the number of words from
Host A to Dev B, and CRC_COUNT is the number of frames in both directions with CRC errors.
shows several switches and the correct ports on which to add performance monitors for a
specified SID-DID pair.
