DGS-3312SR Layer 3 Gigabit Switch 14 PORT MIRRORING COMMANDS The port mirroring commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table. Command Parameters config mirror port enable mirror disable mirror show mirror [add | delete] source ports [rx | tx | both] Each command is listed, in detail, in the following sections. NOTE: As a stand-alone switch or as a master switch in a switch stack, the switch number will be referred to as 15 for all configurations, graphs and tables. NOTE: Port mirroring can only be used for regular ports on the master DGS-3312SR switch. No port mirroring can be done between slave switches in a stacking configuration, and the master switch. config mirror port Purpose Syntax Description Parameters Used to configure a mirror port − source port pair on the switch. config mirror port add source ports [rx | tx | both] 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 one or both is mirrored to the Target port. port − This specifies the Target port (the port where mirrored packets will be sent). The port list is specified by listing the lowest switch number and the beginning port number on that switch, separated by a colon. Then the highest switch number, and the highest port number of the range (also separated by a colon) are specified. The beginning and end of the port list range are separated by a dash. For example, 1:3 specifies 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. add source ports - The port or ports being mirrored. This cannot include the Target port. − This specifies a range of ports that will be 99
