Perfaddeemonitor - Brocade Communications Systems 8 Command Reference Manual

perfAddEEMonitor

Adds an end-to-end monitor to a port.
Synopsis perfaddeemonitor [slot/]port SourceID DestID
Description Use this command to add an end-to-end performance monitor to a port. The performance monitor
counts the number of words received, number of words transmitted, and number of CRC errors
detected using either of the following two conditions:
1. For frames received at the port, the frame SID is the same as and frame DID is the same as
2. For frames transmitted from the port, the frame DID is the same as SourceID and frame SID is
To monitor traffic from host A to device B, add a monitor on port 2, specifying 0x050200 as the SID
and 0x010100 as the DID. The RX count equals the number of words from host A to device B,
whereas the TX count equals the number of words from device B to host A. The CRC count equals
the total number of CRC errors for both directions. Adding a monitor on port 1, specifying
0x010100 as SID and 0X050200 as the DID has a similar effect, except the RX and TX counts are
interchanged.
To monitor traffic between one Initiator host and one target storage device connected to an
Encryption Switch, you must add two monitors because of the manner in which the real initiators or
targets transfer data to VIs and VTs. The first monitor would be added between the initiator SID and
the virtual initiator DID, and the second monitor would be set up between virtual target SID and the
target DID. Refer to the example section for details.
If ISL monitoring is enabled, end-to-end monitors cannot be added to E_Ports. Existing end-to-end
monitors on E_Ports are deleted.
Identical monitors cannot be added to the same port. Two monitors are considered identical if they
have the same SID and DID values after applying the end-to-end mask.
Execution of this command displays a monitor number, which can be used to manipulate
performance monitors.
Notes This command requires an Advanced Performance Monitoring license.
This command is not supported on virtual FC ports (VE/VEX_Port), EX_Port, M (Mirror) ports and
GbE ports.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
Operands This command has the following operands:

DestID; both RX_COUNT and CRC_COUNT are updated accordingly.
the same as DestID; both TX_COUNT and CRC_COUNT are updated accordingly.
For bladed systems only, specifies the slot number of the port on which the
monitor is to be added, followed by a slash (/).
Specifies the number of the port on which the monitor is to be added, relative
to its slot for bladed systems. Use switchShow for a list of valid ports.
