Configuring SPAN and RSPAN
How to Configure SPAN and RSPAN
Command
3. monitor session session_number source
remote vlan vlan-id
4. monitor session session_number
destination {interface interface-id [, | -]
[ingress {dot1q vlan vlan-id | untagged vlan
vlan-id | vlan vlan-id}]}
5. end
Purpose
Specifies the RSPAN session and the source RSPAN VLAN.
session_number—The range is 1 to 68.
vlan-id—Specifies the source RSPAN VLAN to monitor.
Specifies the SPAN session, the destination port, the packet
encapsulation, and the incoming VLAN and encapsulation.
session_number—Enters the number defined in Step 4.
In an RSPAN destination session, you must use the same session
number for the source RSPAN VLAN and the destination port.
interface-id—Specifies the destination interface. The destination
interface must be a physical interface.
Though visible in the command-line help string, encapsulation
replicate is not supported for RSPAN. The original VLAN ID is
overwritten by the RSPAN VLAN ID, and all packets appear on the
destination port as untagged.
(Optional) [, | -]—Specifies a series or range of interfaces. Enter a
space before and after the comma; enter a space before and after
the hyphen.
Enter ingress with additional keywords to enable forwarding of
incoming traffic on the destination port and to specify the
encapsulation type:

dot1q vlan vlan-id—Forwards incoming packets with IEEE
802.1Q encapsulation with the specified VLAN as the default
VLAN.

untagged vlan vlan-id or vlan vlan-id—Forwards incoming
packets with untagged encapsulation type with the specified
VLAN as the default VLAN.
Returns to privileged EXEC mode.
