monitor session
monitor session
Use the monitor session global configuration command on the switch stack or on a standalone switch
to start a new Switched Port Analyzer (SPAN) session or Remote SPAN (RSPAN) source or destination
session, to start a new flow-based SPAN (FSPAN) session or flow-based RSPAN (FRSPAN) source or
destination session, to enable ingress traffic on the destination port for a network security device (such
as a Cisco IDS Sensor Appliance), to add or delete interfaces or VLANs to or from an existing SPAN or
RSPAN session, and to limit (filter) SPAN source traffic to specific VLANs. Use the no form of this
command to remove the SPAN or RSPAN session or to remove source or destination interfaces or filters
from the SPAN or RSPAN session. For destination interfaces, the encapsulation options are ignored with
the no form of the command.

Syntax Description session_number Specify the session number identified with the SPAN or RSPAN session.
The range is 1 to 66.
destination Specify the SPAN or RSPAN destination. A destination must be a physical
port.
interface interface-id Specify the destination or source interface for a SPAN or RSPAN session.
Valid interfaces are physical ports (including type, stack member, module,
and port number). For source interface, port channel is also a valid
interface type, and the valid range is 1 to 48.
encapsulation replicate (Optional) Specify that the destination interface replicates the source
interface encapsulation method. If not selected, the default is to send
packets in native form (untagged).
These keywords are valid only for local SPAN. For RSPAN, the RSPAN
VLAN ID overwrites the original VLAN ID; therefore, packets are always
sent untagged.
ingress (Optional) Enable ingress traffic forwarding.
