Figure 1-2 Remote port mirroring implementation
With the remote port mirroring function enabled, a switch plays one of the following
three roles.
Source switch: The switch to which the monitored port belongs. The source switch
copies the mirrored traffic flows to the remote-probe VLAN, and then through
Layer 2 forwarding, the mirrored flows are sent to an intermediate switch or
destination switch.
Intermediate switch: Switches between the source switch and destination switch
on the network. An intermediate switch forwards mirrored flows to the next
intermediate switch or the destination switch. No intermediate switch is required if
a direct connection exists between the source and destination switches.
Destination switch: The switch to which the destination port for remote mirroring
belongs. It forwards mirrored flows it received from the remote-probe VLAN to the
monitoring device through the destination port.
Note:
When a switch acts as an intermediate switch or destination switch for the remote
mirroring, to realize the data mirroring successfully, you are recommended to configure
redirection on the inbound interface and redirect all the packets in the remote-probe
VLAN to the corresponding outbound interface (intermediate switch) or mirroring
destination port (destination switch).
