End-to-end performance monitoring
17
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 59 shows several switches and the correct ports on which to add performance monitors for
a specified SID-DID pair.

Proper placement of end-to-end performance monitors
Setting a mask for an end-to-end monitor
End-to-end 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.
You specify the masks in the form dd:aa:pp , where dd is the domain ID mask, aa is the area ID
mask, and pp is the AL_PA mask. The values for dd , aa , and pp are either ff (the field must match)
or 00 (the field is ignored). The default EE mask value is ff:ff:ff.
NOTE
Only one mask per port can be set. When you set a mask, all existing end-to-end monitors are
deleted.
End-to-end masks are not supported on the Brocade DCX, DCX-4S, 300, 5100, 5300, 5410, 5424,
5450, 5480, 7800, and VA-40FC models.
On FC4-48 port blades, the upper 32 ports can be addressed only when the area ID and the AL_PA
are used together. For usability concerns, the area ID and the AL_PA cannot be masked separately
for any ports on FC4-48 port blades.
1. Connect to the switch and log in as admin.
2. Enter the perfSetPortEEMask command.
perfsetporteemask [ slotnumber /] portnumber " TxSIDMsk " " TxDIDMsk " " RxSIDMsk "
" RxDIDMsk "
The perfSetPortEEMask command sets the mask for all end-to-end monitors of a port. If any
end-to-end monitors are programmed on a port when the perfSetPortEEMask command is issued,
then a message displays similar to the following example:
switch:admin> perfsetporteemask 1/2, "00:ff:ff"
Changing EE mask for this port will cause ALL EE monitors on this port to be
deleted.
Continue? (yes, y, no, n): [no]
y
The EE mask on port 2 is set and EE monitors on this port are deleted
The perfSetPortEEMask command sets a mask for the Domain ID, Area ID, and AL_PA of the SIDs
and DIDs for frames transmitted from and received by the port.
