Access Gateway considerations for Advanced Performance Monitoring
EE monitors and frame monitors are supported on switches in Access Gateway mode. Top Talker
monitors are not supported on these switches.
EE monitors must be installed on F_Ports. Frame monitors can be installed on F_Ports or N_Ports.
Refer to the Access Gateway Administrator's Guide for additional information.
End-to-end performance monitoring
Use end-to-end (EE) monitoring when you want to monitor throughput between a pair of devices. End-
to-end performance monitoring counts the number of words in Fibre Channel frames for a specified
Source ID (SID) and Destination ID (DID) pair.
To enable EE performance monitoring, you must configure an EE monitor on a port, specifying the SID-
DID pair (in hexadecimal). The monitor counts only those frames with a matching SID and DID.
Each SID or DID has the following three fields:
• Domain ID (DD)
• Area ID (AA)
• AL_PA
For example, the SID 0x118a0f denotes DD 0x11, AA 0x8a, and AL_PA 0x0f.
An EE monitor includes these counts:
• RX_COUNT - Words in frames received at the port
For frames received at the port with the EE monitor installed, the RX_COUNT is updated if the frame
SID is the same as the SID in the monitor and the frame DID is the same as the DID in the monitor.
• TX_COUNT - Words in frames transmitted from the port
For frames transmitted from the port with the EE monitor installed, TX_COUNT is updated if the frame
DID is the same as the SID in the monitor and the frame SID is the same as the DID in the monitor.
Maximum number of EE monitors
The maximum number of end-to-end monitors supported varies depending on the switch model:
• The Brocade DCX 8510, 6505, 6510, 6520, M6505, and 6547 models allow up to 512 end-to-end
monitors shared by all ports in the same ASIC. Also, these models allow up to 256 end-to-end
monitors per port.
• The Brocade DCX, DCX-4S, 5100, VA-40FC, and Brocade Encryption Switch models allow up to
1024 end-to-end monitors shared by all ports in the same ASIC. Also, these models allow up to 256
end-to-end monitors per port.
• The Brocade 300, 5300, 5410, 5424, 5430, 5450, 5460, 5470, 5480, and 7800 models allow up to
768 end-to-end monitors shared by all ports in the same ASIC. Also, these models allow up to 192
end-to-end monitors per port.
The number of interswitch links (ISLs) configured on the switch affects the amount of resources
available for end-to-end monitors.
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.
