Page 328 highlights

Adding end-to-end monitors An end-to-end monitor counts the following items for a port: number of words received, number of words transmitted, and number of CRC errors detected in frames. 4/16 SAN Switch and 4/8 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Brocade 4Gb SAN Switch for HP c-Class BladeSystem, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, and SAN Director 2/128 models allow up to eight end-to-end monitors. The SAN Switch 4/32, SAN Switch 4/32B, 4/64 SAN Switch, 400 MP Router and 4/256 SAN Director models allow up to 256 end-to-end monitors shared by all ports in the same ASIC chip. (The number of interswitch links configured on the switch affects the amount of resources available for end-to-end monitors.) The FC4-48 blade allows end-to-end monitors on all 48 ports. For the FC4-16IP, end-to-end monitors are supported on the ASIC FC ports (ports 0 through 7), but not on the GbE ports. You cannot add end-to-end monitors to interswitch links. Identical end-to-end monitors cannot be added to the same port. Two end-to-end monitors are considered identical if they have the same SID and DID values after applying the end-to-end mask. The monitor count is qualified using either of following conditions: • 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 and CRC_COUNT are 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 and CRC_COUNT are updated accordingly. NOTE: The relationship between the area ID for a port and the port number depends upon the PID format used by the fabric. Refer to "Configuring the PID format" on page 423 for more information. Figure 19 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.

Administering Advanced Performance Monitoring (APM)
Adding end-to-end monitors
An end-to-end monitor counts the following items for a port: number of words received, number of words
transmitted, and number of CRC errors detected in frames.
4/16 SAN Switch and 4/8 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Brocade
4Gb SAN Switch for HP c-Class BladeSystem, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32,
and SAN Director 2/128 models allow up to eight end-to-end monitors.
The SAN Switch 4/32, SAN Switch 4/32B, 4/64 SAN Switch, 400 MP Router and 4/256 SAN Director
models allow up to 256 end-to-end monitors shared by all ports in the same ASIC chip. (The number of
interswitch links configured on the switch affects the amount of resources available for
end-to-end monitors.)
The FC4-48 blade allows end-to-end monitors on all 48 ports.
For the FC4-16IP, end-to-end monitors are supported on the ASIC FC ports (ports 0 through 7), but not on
the GbE ports.
You cannot add end-to-end monitors to interswitch links. Identical end-to-end monitors cannot be added to
the same port. Two end-to-end monitors are considered identical if they have the same SID and DID values
after applying the end-to-end mask.
The monitor count is qualified using either of following conditions:
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 and CRC_COUNT are
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 and CRC_COUNT are
updated accordingly.
NOTE:
The relationship between the area ID for a port and the port number depends upon the PID format
used by the fabric. Refer to ”
Configuring the PID format
” on page 423 for more information.
Figure 19
shows two devices:
Host A is connected to domain 5 (0x05), switch area ID 18 (0x12), AL_PA 0x00 on SwitchX
Dev B is a storage device connected to domain 17 (0x11), switch area ID 30 (0x1e), AL_PA 0xef on
Switch Y.

Setting end-to-end monitors on a port
NOTE:
End-to-end performance monitoring looks at traffic on the receiving port respective to the SID only.
In
Figure 19
, if you add a monitor to slot 2, port 2 on Switch x, specifying Dev B as the SID and Host A as
the DID, no counters (except CRC) will be incremented.
