Configuring RSPAN

Creating an RSPAN Source Session

Beginning in privileged EXEC mode, follow these steps to start an RSPAN source session and to specify
the monitored source and the destination RSPAN VLAN:

Command

Purpose

Step 1

configure terminal

Enter global configuration mode.

Step 2

no monitor session {session_number | all |
local | remote}

Clear any existing RSPAN configuration for the session.

For session_number, specify the session number identified with this
RSPAN session.

Specify all to remove all RSPAN sessions, local to remove all local
sessions, or remote to remove all remote SPAN sessions.

Step 3

monitor session session_number source
interface interface-id [, | -] [both | rx | tx]

Specify the RSPAN session and the source port (monitored port).

For session_number, specify the session number identified with this
RSPAN session.

For interface-id, specify the source port to monitor. Valid interfaces
include physical interfaces and port-channel logical interfaces
(port-channel port-channel-number).

(Optional) [, | -] Specify a series or range of interfaces. Enter a space
before and after the comma; enter a space before and after the
hyphen.

(Optional) Specify the direction of traffic to monitor. If you do not
specify a traffic direction, the source interface sends both sent and
received traffic.

both—Monitor both received and sent traffic.

rx—Monitor received traffic.

tx—Monitor sent traffic.

Step 4

monitor session session_number
destination remote vlan vlan-id
reflector-port interface

Specify the RSPAN session, the destination remote VLAN, and the
reflector port.

For session_number, enter the session number identified with this
RSPAN session.

For vlan-id, specify the RSPAN VLAN to carry the monitored traffic
to the destination port. (See the

“Creating or Modifying an Ethernet

VLAN” section on page 12-8

for more information about creating an

RSPAN VLAN.)

For interface, specify the interface that will flood the RSPAN traffic
onto the RSPAN VLAN.

Step 5

end

Return to privileged EXEC mode.

Step 6

show monitor [session session_number]

Verify your entries.

Step 7

copy running-config startup-config

(Optional) Save your entries in the configuration file.
