perfAddEEMonitor

Add end-to-end monitor to a port.
Synopsis
perfAddEEMonitor port, "SourceID", "DestID"
Availability
admin
Description
Use this command to add an End-to-End monitor to a port. The monitor counts the number of
words received, number of words transmitted and number of CRC errors detected with frames
qualified using either of following two conditions.
•
for frames received at the port (with End-to-End monitor installed) 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.
•
for frames transmitted from the port (with End-to-End monitor installed) the frame DID is the
same as "SourceID" and frame SID is the same as "DestID", TX_COUNT will be updated
accordingly.
Depending on the application, any port along the routing path can be selected for such monitoring.
For example, to monitor traffic flowing from point A, receiving at port C and transmitting at port D
to reach point B, and the traffic flowing back from B to A. You can install a monitor on port C,
specify point A as "SourceID" and point B as "DestID". Then RX_COUNT counts the traffic flow
from A to B, CRC_COUNT counts the frames with CRC error from A to B. TX_COUNT counts
the traffic from B to A.
Similarly, you can install a monitor on port D, specify point B as "SourceID" and point A as
"DestID". Then RX_COUNT counts the traffic from B to A, CRC_COUNT counts the frames with
CRC errors from B to A and TX_COUNT counts the traffic from A to B.
End-to-End monitors traffic on receiving port, respective to "SourceID", only, which implies in the
above example, install a monitor on port D with point A as "SourceID" and point B as "DestID"
will not generate any counts.
Both RX_COUNT and CRC_COUNT are associated with frames received at port. TX_COUNT is
associated with frames transmitted from port.
After a successful execution of this command, a monitor number is displayed. The monitor number
is provided for easy manipulation of these performance monitors.
Operands
This command has the following operands:
port
SourceID
DestID
1-142
Specify the port number where you want to add an EE frame monitor. This
operand is required.
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 ALPA
ID. For example, 0x058e0f, has a Domain ID of "5", an Area ID of "8e" and an
ALPA ID of "f".
Specify the 3-byte DID (Destination ID) of the destination device. It should be in
"0xDDAAPP" format, where DD is Domain ID, AA is Area ID and PP is ALPA
ID. For example, 0x058e0f, has a Domain ID of "5", an Area ID of "8e" and an
ALPA ID of "f".
