Sending traffic using a Fabric Assigned WWN
If you want to use a Fabric Assigned WWN (FA-WWN), you need to set the FA-WWN on the SIM port
using the Dynamic Fabric Provisioning command, fapwwn -assign. For details, refer to the "Dynamic
Fabric Provisioning" section of the Fabric OS Administrator's Guide.
CAUTION
If the fapwwn command is used to assign a user-defined Port WWN to a SIM port, it is the
person making the assignment’s responsibility to not assign a Port WWN that duplicates one
already in the fabric. If there is a duplicated WWN, both entries will be removed from the Name
Sever database. This has a high probability of disrupting traffic.
Flow Generator and High Availability
On a High Availability (HA) failover, HA reboot, or a power cycle and reboot, both local and remote
flows remain active. When SIM ports come back online from an HA failover or HA reboot event, local
flows are re-created and reactivated, and local traffic is restarted. Inactive flows are re-created but not
activated by an HA failover, HA reboot, or a power cycle and reboot.
ATTENTION
For the first 39 flows that can be learned for Flow Generator, a HA failover, HA reboot, or a power cycle
and reboot event may cause different sub-flows to be re-created, as the flow order depends on the zone
database.
If the sys_gen_all_simports flow was active prior to a HA failover, the flow will be replayed after the HA
failover with all the SIM ports that are configured on the switch.
Refer to High Availability and Flow Vision on page 32 and Notes on predefined flows on page 62 for
more information.
Flow Generator and MAPS
The Monitoring and Alerting Policy Suite (MAPS) can be used to monitor SIM port traffic thresholds
while Flow Generator flows are running.
MAPS treats SIM ports as F_Ports, so MAPS can issue warnings on these ports if threshold values are
triggered. If you do not want to see MAPS warnings for SIM ports, you must disable MAPS monitoring
for those ports.
