Switch Port-Mirroring
Port-mirroring configures the switch to copy all traffic associated with one or more ports. The monitor
port can be connected to a network analyzer or RMON probe for packet analysis. The system uses a
traffic filter that copies a group of traffic to the monitor port.
NOTE
Port mirroring is not supported with CPU-generated traffic.
You can define the traffic filter based on the physical port. All data that traverses the port, regardless of
VLAN configuration, is copied to the monitor port.
Up to eight mirroring filters and one monitor port can be configured. Once a port is specified as a
monitor port, it cannot be used for any other function.
NOTE
Frames that contain errors are not mirrored.
The mirrored port only transmits tagged frames. This allows you to mirror multiple ports or VLANs to
a mirror port, while preserving the ability of a single protocol analyzer to track and differentiate traffic
within a broadcast domain (VLAN) and across broadcast domains (for example, across VLANs when
routing).
To enable port mirroring, use the following command:
enable mirroring to port [<port>] tagged
To configure the switch for port mirroring, use the following command:
configure mirroring add [<mac_address> | vlan <vlan name> {ports <port number>} |
ports <portnumber> {vlan <vlan name>}]
