LevelOne GSW-2692 manual Configuring Port Mirroring, 114

3 Configuring the Switch

CLI – Specify any interface, and then enter the threshold. The following disables broadcast storm control for port 1, and then sets broadcast suppression at 600 octets per second for port 2 (which applies to all ports).

Console(config)#interface ethernet 1/1		4-108
Console(config-if)#no switchport broadcast		4-114
Console(config-if)#exit
Console(config)#interface ethernet 1/2
Console(config-if)#switchport broadcast octet-rate 600		4-114
Console(config-if)#end
Console#show interfaces switchport ethernet 1/2		4-117

Configuring Port Mirroring

You can mirror traffic from any source port to a target port for real-time analysis. You can then attach a logic analyzer or RMON probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner.

Command Usage

Source	Single
port(s)	target
	port

•Monitor port speed should match or exceed source port speed, otherwise traffic may be dropped from the monitor port.

•All mirror sessions have to share the same destination port.

•When mirroring port traffic, the target port must be included in the same VLAN as the source port.

Command Attributes

•Mirror Sessions – Displays a list of current mirror sessions.

•Source Unit – The unit whose port traffic will be monitored.

•Source Port – The port whose traffic will be monitored.

•Type – Allows you to select which traffic to mirror to the target port, Rx (receive), or Tx (transmit).
