Monitoring Fibre Channel routed fabrics

NOTE
You cannot create a learned flow in a trunk group.
The following example displays the trunked ports and then creates four flows, one for each member
of the trunk group identified by the switchshow command.
switch:admin> switchshow
24 24 021800 id N16 Online FC E-Port 10:00:00:05:33:e5:3c:d4 "Odin" (downstream)(Trunk master)
25 25 021900 id N16 Online FC E-Port (Trunk port, master is Port 24 )
26 26 021a00 id N16 Online FC E-Port (Trunk port, master is Port 24 )
27 27 021b00 id N16 Online FC E-Port (Trunk port, master is Port 24 )
switch:admin> flow -create f1 -feature monitor -egrport 24 -srcdev 022b00 -dstdev 033a00
switch:admin> flow -create f2 -feature monitor -egrport 25 -srcdev 022b00 -dstdev 033a00
switch:admin> flow -create f3 -feature monitor -egrport 26 -srcdev 022b00 -dstdev 033a00
switch:admin> flow -create f4 -feature monitor -egrport 27 -srcdev 022b00 -dstdev 033a00
Monitoring Fibre Channel routed fabrics
When creating flow monitors on EX_Ports, you can use either a WWN or a Fibre Channel ID (FCID) for the
source device (srcdev) and destination device (dstdev). Inter-Fabric Link (IFL) flows can be monitored
only on 16 Gbps-capable EX_Ports in a Fibre Channel router. IFL flows are not supported on E_Ports or
F_Ports.
Even though a flow definition is always created in the backbone fabric, the perspective of the flow
is from the edge fabric. In the following examples, the flow definitions are based on the Edge 1
Fabric’s perspective.
When monitoring an FC router fabric, you may find it simpler to use port WWNs rather than proxy
IDs in your flow definitions. This is because you do not need to locate and map the proxy IDs for the
actual source and destination devices.
Monitoring FC router fabrics using port WWNs
The following examples present the flow definitions using deviceidmode set to WWN mode.
flow --control -deviceidmode wwn
