> # Suppressing Domain Format SW-RSCNs

> A domain format SW-RSCN is sent whenever the local switch name or the local switch management IP address changes. This SW-RSCN is sent to all other domains and switches over the ISLs. The remote switches can issue GMAL and GIELN commands to the switch that initiated the domain format SW-RSCN to determine what changed. Domain format SW-RSCNs can cause problems with some non-Cisco MDS switches (refer to the Cisco MDS 9000 Family Switch-to-Switch Interoperability Configuration Guide).

> Note You cannot suppress transmission of port address or area address format RSCNs.
