Monitoring The Traffic From Host A To Dev B; Monitoring The Traffic From Dev B To Host A; Setting A Mask For Ee Monitors; Setting Ee Monitors On A Port - HP A7533A - Brocade 4Gb SAN Switch Base User Manual

NOTE: EE performance monitoring looks at traffic on the receiving port respective to the SID only. In
Figure 10, 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.

Setting EE monitors on a port

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, 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.

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, 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.
Figure 11 shows several switches and the correct ports on which to add performance monitors for a
specified SID-DID pair.

Proper placement of EE performance monitors

Setting a mask for EE monitors

EE monitors count the number of words in Fibre Channel frames that match a specific SID-DID pair. If you
want to match only part of the SID or DID, you can set a mask on the port to compare only certain parts of
the SID or DID. By default, the frame must match the entire SID and DID to trigger the monitor. By setting a
mask, you can choose to have the frame match only one or two of the three fields (Domain ID, Area ID,
and AL_PA) to trigger the monitor.
