Configuration Requirements
• The switch can have one port mirroring pair (one source port and one observer port) at a
time.
• The source port can be a network port, AP access port, or wired authentication port.
• The observer port must be a network port, and cannot be a member of any VLAN or port
group.
Configuring Port Mirroring
To configure port mirroring, use the following command to specify the source and observer ports:
set port mirror
source-port
observer
observer-port
For example, to set port 2 to monitor port 1’s traffic, use the following command:
DWS-1008#
set port 1 observer 2
Attach a protocol analyzer to the observer port; in this example, port 2.
Displaying the Port Mirroring Configuration
To display the port mirroring configuration on a switch, use the following command:
DWS-1008#
show port mirror
Port 1 is mirrored to port 2
Clearing the Port Mirroring Configuration
To clear the port mirroring configuration from a switch, use the following command:
clear port mirror
Remotely Monitoring Traffic
Remote traffic monitoring enables you to snoop wireless traffic, by using a Distributed AP as a sniffing
device. The AP copies the sniffed 802.11 packets and sends the copies to an observer, which is typically
a protocol analyzer such as Ethereal or Tethereal.
