DGS-3224TGR:4# 120 DGS-3224TGR Layer 2 Gigabit Ethernet Switch User's Guide 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 config mirror port enable mirror disable mirror show mirror Parameters <port> [add|delete] source ports <portlist> [rx|tx|both] Each command is listed, in detail, in the following sections. config mirror port Purpose Syntax Used to conigure a mirror port - source port pair on the switch. config mirror port <port> add source ports <portlist> [rx|tx|both] 121 DGS-3224TGR Layer 2 Gigabit Ethernet Switch User's Guide config mirror port 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. <port> - This specifies the Target port (the port where mirrored packets will be sent). <portlist> - 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 beginning port number on that switch and the highest port number of the range. The beginning and end of the port list range are separated by a dash. 3-4 specifies all of the ports between port 3 and port 4 - in numerical order. rx - Allows the mirroring of only packets received (flowing into) the port or ports in the port list. tx - Allows the mirroring of only packets sent (flowing out of) the port or ports in the port list. both - Mirrors all the packets received or sent by the port or ports in the port list. Parameters 122 DGS-3224TGR Layer 2 Gigabit Ethernet Switch User's Guide config mirror port Restrictions Only administrator-level users can issue this command. Example Usage: To add the mirroring ports: DGS-3224TGR:4#config mirror port 10 add source ports 1-5 both Command: config mirror port 10 add source ports 1-5 both Success. DGS-3224TGR:4# config mirror delete Purpose Syntax Description Used to delete configuration| a port mirroring config mirror <port> delete source <portlist> [rx|tx|both] This command is used to previously entered port configuration. delete a mirroring Parameters <port> - This specifies the Target port (the port where mirrored packets will be sent). <portlist> - This specifies a range of ports that will be mirrored. That is, a range of ports for which all traffic will be copied and 123 DGS-3224TGR Layer 2 Gigabit Ethernet Switch User's Guide config mirror delete sent to the Target port. rx - Allows the mirroring of only packets received (flowing into) the port or ports in the port list. tx - Allows the mirroring of only packets sent (flowing out of) the port or ports in the port list. [. . . ] None. Usage Example: To enable SSH: DGS-3224TGR:4#enable ssh Command: enable ssh Success. DGS-3224TGR:4# disable ssh Purpose Syntax Description Parameters Restrictions Used to disable SSH. disable ssh This command allows you to disable SSH on the switch. None. Usage Example: 222 DGS-3224TGR Layer 2 Gigabit Ethernet Switch User's Guide To disable SSH: DGS-3224TGR:4#disable ssh Command: disable ssh Success. [. . . ]
