FIGURE 2 Learning support in a Fibre Channel Routing fabric
The fixed parameters of a learning flow on an E_Port or an EX_Port should use the following
combinations when defining flows using specific ingress or egress ports:
• For flows using an ingress port (ingrport), the real source ID of the source device and the proxy ID of
the destination device.
• For flows using an egress port (egrport), the proxy ID of the source device and the real destination ID
of the destination device.
The flow --show output for an E_Port or an EX_Port will use the flow definition; in this output the proxy
ID of the destination device will be reported for flows defined using the ingress port, and the proxy ID of
the source device will be reported for flows defined using the egress port.
Monitoring flows using the learning functionality on page 53 provides examples of both the flow
command and the flow output.
Configuring Flow Monitor for a trunk group
Flow Monitor supports monitoring trunk ports subject to the following conditions:
• You must create the same flow on all trunk member ports.
• If you create a flow on a slave port without using the -noactivate keyword with the flow command,
this flow is then automatically activated when the slave port becomes the master port.
• After a switch initialization or a recovery (cold or warm), existing flows are re-created on both master
and slave ports, but only those flows associated with the master port are activated.
To configure Flow Monitor on a trunk group, use the following steps.
1. Identify your trunk group members using the switchshow command.
2. Create individual flow monitors for each member of the trunk group using the flow -create command.
