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
Example 27-12 Displays Register Device Information
switch# show rscn scr-table vsan 1
SCR table for VSAN: 1
---------------------------------------------
FC-ID
---------------------------------------------
0x1b0300
Total number of entries = 1
The SCR table is not configurable. It is populated when hosts send SCR frames with RSCN information.
Note
If hosts do not receive RSCN information, then the show rscn scr-table command will not return entries.
Example 27-13 Displays RSCN Counter Information
switch# show rscn statistics vsan 1
Statistics for VSAN: 1
-------------------------
Number of SCR received
Number of SCR ACC sent
Number of SCR RJT sent
