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 6510
• 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 co-exist on the same port.
Co-existence 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
might be inaccurate.
Adding end-to-end monitors
1. Connect to the switch and log in as admin.
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 63 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 63 Setting end-to-end monitors on a port
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
On Domain 1, add a monitor to the F_Port, as follows:
switch:admin> perfaddeemonitor 2/2 "0x011200" "0x021e00"
This monitor (Monitor 1) counts the frames that have an SID of 0x011200 and a DID of 0x021e00.
For Monitor 1, 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.
