Creating an RSPAN Destination Session and Configuring Incoming Traffic
Command
1.
configure terminal
2.
no monitor session {session_number | all |
local | remote}
Purpose
Enters global configuration mode.
Enters the VLAN ID of the RSPAN VLAN created from the source
switch, and enters VLAN configuration mode.
If both switches are participating in VTP and the RSPAN VLAN ID is
from 2 to 1005, Steps 2 through 4 are not required because the
RSPAN VLAN ID is propagated through the VTP network.
Identifies the VLAN as the RSPAN VLAN.
Returns to global configuration mode.
Removes any existing RSPAN configuration for the session.
session_number—The range is 1 to 68.
all—Removes all RSPAN sessions
local—Removes all local sessions
remote—Removes all remote SPAN sessions.
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 RSPAN session and the destination interface.
session_number—Enters the number defined in Step 6.
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.
Returns to privileged EXEC mode.
Purpose
Enters global configuration mode.
Removes any existing SPAN configuration for the session.
