MAC address learning is disabled on the RSPAN VLAN.
You can use an output access control list (ACL) on the RSPAN VLAN in the RSPAN source switch
to filter the traffic sent to an RSPAN destination.
RSPAN does not support BPDU monitoring.
Do not configure RSPAN VLANs as sources in VSPAN sessions.
You can configure any VLAN as an RSPAN VLAN as long as all participating network devices
support configuration of RSPAN VLANs and you use the same RSPAN VLAN for each RSPAN
session in all participating network devices.
Entering SPAN configuration commands does not clear previously configured SPAN parameters.
You must enter the no monitor session command to clear configured SPAN parameters.
