DES-3326SR Layer 3 Fast Ethernet Switch CLI Reference Manual config mirror port Purpose Used to configure a mirror port − source port pair on the switch. Syntax config mirror port add source ports [rx/tx/both] Description This command allows a range of ports to have all of their traffic also sent to a designated port − where a network sniffer or other device can monitor the network traffic. In addition, you can specify that only traffic received by or sent by or both is mirrored to the Target port. Parameters − This specifies the Target port (the port where mirrored packets will be sent). − specifies a range of ports to be configured. Ports are specified by entering the lowest port number in a group, and then the highest port number in a group, separated by a dash. So, a port group including the switch ports 1, 2, and 3 would be entered as 1-3. Ports that are not contained within a group are specified by entering their port number, separated by a comma. So, the port group 1-3 and port 26 would be entered as 1-3, 26. Additional ports can be individually entered by their port number, separated by commas. rx − Allows the mirroring of only packets received (flowing into) the port or ports in the port list. 168 Port Mirroring Commands
