For example, display port 1/1 information：

Switch# show interface ge1/1

For example, displays all ports information：

Switch# show interface

3.2 Configuration MIRROR

The port mirroring is a very useful function for monitoring the flow of packets received and

sent by one or more ports. It can use mirroring ports to monitor packets received and sent from

one or more ports。switches support port mirroring capabilities, mirroring the port's ability to

monitor incoming data from other ports and the data that goes out. A mirrored port can monitor

multiple ports at the same time。This section focuses on the configuration of MIRROR, including

the following：

 Configuration of the MIRROR listen on port and is listening on port

 Display the configuration of MIRROR

3.2.1 Configuration of the MIRROR listen on port and

is listening on port

When the administrator configures the monitoring port, you need to enter the interface

configuration mode to set up the monitored port. For example, setting port ge1/1 monitoring port

ge1/2, you need to enter the port ge1/1 and type the command：

Switch(config-ge1/1)# mirror interface ge1/2 direction both

At this point, the port ge1/1 is set to the listening port, and the ge1/2 is set to the listening

port。

The command to set up the monitored port is as follows：

Switch(config-ge1/1)#mirror interface <if-name> direction {both | receive | transmit}

At this time, ge1/1 port is set to monitor port, <if-name> is set to be listening port, while

behind the {both receive transmit} | | pointed out the direction of monitoring：Receive represents

the received packets; the transmit monitors the packets sent; the both monitors all packets sent and

received. such as：

Switch(config-ge1/1)#mirror interface ge1/2 direction both
