End-to-end performance monitoring
The monitor count is qualified using either of the following conditions:
•
•
Virtual Fabrics considerations: If Virtual Fabrics is enabled, the Brocade DCX, DCX-4S, and 5300
models allow up to 256 end-to-end monitors on one logical switch. The Brocade 5100 and VA-40FC
allow up to 337 end-to-end monitors on one logical switch.

Adding end-to-end monitors

1. Connect to the switch and log in as admin.
2. Enter the following command:

FIGURE 58
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).
Example of 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:
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.
Example of 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.
386
For frames received at the port with the end-to-end monitor installed, the frame SID is the
same as "SourceID" and the frame DID is the same as "DestID". The RX_COUNT updated
accordingly.
For frames transmitted from the port with the end-to-end monitor installed, the frame DID is
the same as "SourceID" and the frame SID is the same as "DestID". The TX_COUNT updated
accordingly.
perfaddeemonitor [slotnumber/]portnumber sourceID destID
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.
