Operation Manual - QoS/ACL
Quidway S3500 Series Ethernet Switches
You may specify a mirroring port to accept the monitoring of:
Inbound packets
Outbound packets
Both inbound and outbound packets
You may also specify a monitor port to monitor:
Only the inbound packets on the specified mirroring ports
Only the outbound packets on the specified mirroring ports
You may configure port mirroring using the commands described in the following table.
Perform the following configuration in system view.
Table 2-41 Configuring port mirroring
Configure a monitor port.
Configure one or more mirroring
ports.
Disable the configuration of mirroring
port or ports.
Disable the configuration of the
monitor port.
When configuring port mirroring, you must configure a monitor port prior to mirroring
port (or ports). When disabling port mirroring, you can disable the monitor port only
after disabling all the mirroring ports.
Each switch supports two monitor ports (also known as mirroring destination ports) at
most. These two ports can function to respectively observe the inbound packets and
outbound packets on one or more specified ports. A monitor port can observe as many
mirroring ports as possible if it is applied to monitor the inbound packets, but it can
observe only up to eight mirroring ports if it is applied to monitor the outbound packets.
Inbound packets containing errors (CRC or fragment error for example) are beyond the
scope of monitoring. Outbound packets being monitored will be duplicated to the
appropriate monitor port even if they are forwarded to CPU en route.
