Specifying VLANs to Filter, page 32-16
On each switch stack, you can configure a maximum of 2 source sessions and 64 RSPAN destination
sessions. A source session is either a local SPAN session or an RSPAN source session.
For SPAN sources, you can monitor traffic for a single port or VLAN or a series or range of ports
or VLANs for each session. You cannot mix source ports and source VLANs within a single SPAN
session.
The destination port cannot be a source port; a source port cannot be a destination port.
You cannot have two SPAN sessions using the same destination port.
When you configure a switch port as a SPAN destination port, it is no longer a normal switch port;
only monitored traffic passes through the SPAN destination port.
Entering SPAN configuration commands does not remove previously configured SPAN parameters.
You must enter the no monitor session {session_number | all | local | remote} global configuration
command to delete configured SPAN parameters.
