source global configuration command. To remove the SPAN or RSPAN session or to remove source interfaces
from the SPAN or RSPAN session, use the no form of this command.

Syntax Description
session_number
Specifies the 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.
interface interface-id
(Optional) Specifies a series of interfaces or VLANs, or separates a range
of interfaces or VLANs from a previous range. Enter a space before and
after the comma.
,
(Optional) Specifies a range of interfaces or VLANs. Enter a space before
and after the hyphen.
-
(Optional) Specifies the traffic direction to monitor. If you do not specify
a traffic direction, the source interface sends both transmitted and received
traffic.
both | rx | tx
(Optional) Specifies the remote VLAN for an RSPAN source or destination
session. The range is 2 to 1001 and 1006 to 4094.
The RSPAN VLAN cannot be VLAN 1 (the default VLAN) or VLAN IDs
1002 to 1005 (reserved for Token Ring and FDDI VLANs).
remote
When used with only the ingress keyword, sets default VLAN for ingress
traffic.
vlan vlan-id
Command Default
No monitor sessions are configured.
On a source interface, the default is to monitor both received and transmitted traffic.
On a trunk interface used as a source port, all VLANs are monitored.
