Adds an end-to-end monitor to a port.
Synopsis
perfaddeemonitor [slotnumber/]portnumber SourceID DestID
Availability
admin
NOTE: This command requires a Performance Monitor license
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:
• For frames received at the port, the frame SID is the same as SourceID and frame DID is the same as
DestID, both RX_COUNT and CRC_COUNT will be updated accordingly. Note that the CRC_COUNT
counts the CRC errors detected with the frames received at or transmitted from the associated port.
• For frames transmitted from the port, the frame DID is the same as SourceID and frame SID is the same
as DestID, both TX_COUNT and CRC_COUNT will be updated accordingly.
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.
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.
After a successful execution of this command, a monitor number is displayed. The monitor number is
provided for manipulation of these performance monitors.
Operands
This command has the following operands:
perfAddEEMonitor
slotnumber For bladed systems only, this operand specifies the slot number of the
port on which the monitor is to be added, followed by a slash (/).
portnumber 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.
SourceID Specify the 3-byte SID (Source ID) of the originator device. It should
be in 0xDDAAPP format, where DD is domain ID, AA is area ID and
PP is AL_PA ID. For example, 0x050200 has a domain ID of 5, an
area ID of 2, and an AL_PA ID of 0. SourceID and DestID both
cannot be 0x000000.
