has been configured, MAC address learning will still not be re-started on the
RSPAN uplink ports.
IEEE 802.1X – RSPAN and 802.1X are mutually exclusive functions. When 802.1X
is enabled globally, RSPAN uplink ports cannot be configured, even though
RSPAN source and destination ports can still be configured. When RSPAN uplink
ports are enabled on the switch, 802.1X cannot be enabled globally.
RSPAN uplink ports cannot be configured to use IEEE 802.1X Port Authentication,
but RSPAN source ports and destination ports can be configured to use it
Port Security – If port security is enabled on any port, that port cannot be set as an
RSPAN uplink port, even though it can still be configured as an RSPAN source or
destination port. Also, when a port is configured as an RSPAN uplink port, port
security cannot be enabled on that port.

rspan source

Use this command to specify the source port and traffic type to be mirrored remotely.
Use the no form to disable RSPAN on the specified port, or with a traffic type
keyword to disable mirroring for the specified type.
