Chapter18 Configuring SPAN and RSPAN
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
Step1 configure terminal Enter global configuration mode.
Step2 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.
Step3 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.
Step4 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.
Step5 end Return to privileged EXEC mode.
Step6 show monitor [session session_number] Verify your entries.
Step7 copy running-config startup-config (Optional) Save your entries in the configuration file.
