DES-3226S Layer 2 Fast Ethernet Switch User's Guide config mirror port Purpose Used to conigure 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 desnigated 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). − This specifies a range of ports that will be mirrored. That is, a range of ports for which all traffic will be copied and sent to the Target port. The port list is specified by listing the lowest switch number and the beginning port number on that switch, separated by a colon. Then highest switch number, and the highest port number of the range (also separeted by a colon) are specified. The beginning and end of the port list range are seperated by a dash. For example, 1:3 would specify switch number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3-2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4 − in numerical order. rx − Allows the mirroring of only packets 158 Port Mirroring Commands
