About RSCN Information

Apart from sending these events to registered hosts, a switch RSCN (SW-RSCN) is sent to all reachable
switches in the fabric.
Note
The switch sends an RSCN to notify registered nodes that a change has occurred. It is up to the nodes to query
the name server again to obtain the new information. The details of the changed information are not delivered
by the switch in the RSCN sent to the nodes.

Displaying RSCN Information

Use the show rscn command to display RSCN information (see Examples
Information, on page 229

Note
The SCR table is not configurable. It is populated when hosts send SCR frames with RSCN
information. If hosts do not receive RSCN information, then the show rscn scr-table command will
not return entries.
