6.10.1 Mirror
Port mirroring refers to copy data from the port which need to be monitored to appointed monitoring port
for analysis and monitoring. Ethernet switch supports many-for-one mirror which means messages from several
ports can be copied to a monitored port. User can appoint the direction of monitored message, such as only
monitoring of transmitted messages of appointed port. The device configures port mirroring function through port
mirroring group. Each group includes a monitored port and a group of mirror ports. Total bandwidth of mirroring
is not more than that of monitored port. It is good to monitor and manage its internal network data when using
port mirroring in a company. It is also good to locate the failure when network is cut up.
Operating method: Enable port mirroring, select monitored port, select mirror port. Monitored port can
get data from mirror port and select monitored data at last: all data or egress data. Select Apply. As shown in
figure 6.10.1,6.10.2
