End-to-end performance monitoring

Virtual Fabrics considerations: If Virtual Fabrics is enabled, the Brocade DCX, DCX-4S, DCX 8510
and 5300 models allow up to 256 end-to-end monitors on one logical switch. The Brocade 5100,
6510, 6520, and VA-40FC allow up to 341 end-to-end monitors on one logical switch.
Supported port configurations for EE monitors
You can configure EE monitors on F_Ports and, depending on the switch model, on E_Ports. The
following platforms support EE monitors on E_Ports:
•
Brocade 6505
•
Brocade 6510
•
Brocade 6520
•
Brocade DCX 8510 family
Identical EE monitors cannot be added to the same port. Two EE monitors are considered identical
if they have the same SID and DID values after applying the end-to-end mask.
An EE monitor and a port Top Talker monitor cannot coexist on the same port.
Coexistence of EE monitors and Top Talker monitors on ports belonging to the same ASIC is not
recommended because the statistics for the same flow going through ports on the same ASIC may
be inaccurate.
Adding EE monitors
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the following command:
perfaddeemonitor [ slotnumber / ] portnumber sourceID destID
When you add an EE monitor to a port, specify the sourceID and destID in the ingress direction. For
example, Figure 64 shows two devices:
•
Host A is connected to domain 1 (0x01), switch area ID 18 (0x12), AL_PA 0x00.
•
Dev B is a storage device connected to domain 2 (0x02), switch area ID 30 (0x1e), AL_PA
0x00.
FIGURE 64
Setting end-to-end monitors on a port
End-to-end performance monitoring looks at traffic on SID and 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 and Rx
counters are reversed).
Example of monitoring the traffic from Host A to Dev B
On Domain 1, add a monitor to the F_Port, as follows:
switch:admin> perfaddeemonitor 2/2 "0x011200" "0x021e00"
Domain 1
Host A Dev B
SID = 0x011200
DID = 0x021e00
Domain 2
