The RSPAN function broadcasts mirrored packets from the source switch to the destination
switch in the RSPAN VLAN. Interfaces between the source switch, intermediate switch, and
destination switch must be added to the RSPAN VLAN.
Mirrored packets are forwarded to the intermediate switch through the observing port on the
source switch. Then the intermediate switch broadcasts mirrored packets to the observing port
on the destination switch in the RSPAN VLAN.
The observing port on the destination switch receives mirrored packets.
Through the RSPAN function, packets on a specified interface or VLAN, with a specified source
or destination MAC address, or matching a classifier can be copied to an observing port on a
remote device.

8.2 Configuring Local Port Mirroring

This section describes how to configure local port mirroring.

8.2.1 Establishing the Configuration Task

Applicable Environment
When all incoming or outgoing packets passing through a specified interface of the S3700 need
to be monitored, you can configure local port mirroring if the mirrored port is located on the
same S3700 as the observing port.
Pre-configuration Tasks
None.
Data Preparation
To configure local port mirroring, you need the following data.
No.

The source switch is the Switch where the mirrored port is located.
The destination switch is the Switch where the observing port is located.
The intermediate switch is a device between the source switch and destination switch.
NOTE
The source switch and destination switch can also be directly connected to implement the RSPAN
function.
