Fabric OS Commands
"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.
After a successful execution of this command, a monitor number is displayed. The
monitor number is provided for easy manipulation of these performance monitors.
Note:
Operands
This command has the following operands:
slotnumber
(V4.1.x only)
portnumber
SourceID
476
This command requires an Advanced Performance Monitoring license.
Specify the slot number for a StorageWorks Core switch.
For all other switches this operand is not required. The slot
number must be followed by a slash ( / ) and the port
number, so that each port is represented by both slot
number (1 through 4, or 7 through 10), and port number
(0 through 15).
The StorageWorks Core switch has a total of 1–10 slots.
Slot number 5 and 6 are control processor cards, and slot
1 through 4, and 7 through 10, are port cards. On each
port card, there are 16 ports counted from the bottom, 0 to
15.
Specify a port number. Valid values for port number vary
depending on the switch type. 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 AL_PA ID. For example,
0x058e0f, has a Domain ID of "5," an Area ID of "8e,"
and an AL_PA ID of "f."
