In Fabric OS v7.0.0, the restrictions on addressing have been lifted. An IPv4 subnet can span multiple
GbE interfaces, and you can now have multiple IPv6 addresses with the same prefix configured on
different GbE interfaces on the same extension switch or blade.

portcfg mirrorport - Configure a mirror port on the local port.
portcfg rscnsupr - Manage registered state change notification (RSCN) suppression on the local
port.
For bladed systems only, specifies the slot number of the port to be configured,
followed by a slash (/).
Specifies a single port or a range of ports, for example, 3-22 or 1/3-8. port ranges
are supported only with the rscnsupr option.
Manages Registered State Change Notification (RSCN) suppression on the local
port. RSCN suppression is configurable only on FC ports. The syntax for portCfg
rscnsupr is as follows:
portcfg rscnsupr [slot/]port[-port] mode
The following modes are supported with the rscnsupr option:
--disable
Disables the configuration. When disabled, device changes on the port generate
an RSCN to all other end devices that are zoned with this one. By default, RSCN
suppression is disabled on all ports.
--enable
Enables the configuration. When enabled, any device changes on the port will not
generate an RSCN to any other end device.
Configures a mirror port on the local port. The port mirroring feature reroutes data
frames between two devices to the mirror port. Port mirroring can aid in
troubleshooting common FC end-to-end communication problems. The command
prompts for confirmation that the specified port be enabled as a mirror port. Once
a port is configured as a mirror port, the port can only be used as part of a mirror
connection. Port Mirroring is not supported over FCIP links (VE tunnels).
The syntax for portCfg mirrorport is as follows:
portcfg mirrorport [slot/]port mode
