Netgear M4300-24X24F (XSM4348S) - Stackable Managed Switch with 48x10G including 24x10GBASE-T and 24xSFP+ Layer 3 Guia Do Administrador

In the previous figure, Switch 1 is the source switch, Switch 2 and Switch 3 are intermediate 
switches, and Switch 4 is the destination switch.

You must configure the ports that are connected to the destination switch with tagging, with 
the VLAN ID as the RSPAN VLAN. You must also configure the ports on the intermediate 
switches that are connected to the source switch and destination switch with the RSPAN 
VLAN.

 

Only one RSPAN VLAN is supported.

On the source switch, the traffic that is received on and transmitted from source port (1/0/1) is 
tagged with the RSPAN VLAN and transmitted on the configured reflector port. The reflector 
port (1/0/2) is the physical interface that carries the mirrored traffic to the destination switch.

The intermediate switches forward the incoming tagged traffic to the destination switch. 
Enable RSPAN VLAN egress tagging on the ports of the intermediate switches that are 
connected to the destination switch. 

The destination switch accepts all the packets that are tagged with the RSPAN VLAN and 
mirrors the packets on the destination port to which you must connect a traffic analyzer.

The original tag is retained at the destination switch. Mirrored traffic has double tagging: The 
inner tag is the original VLAN ID and the outer tag is the RSPAN VLAN ID.

On the source switch (Switch 1), configure the following settings:

Source ports (the ports for which the traffic must be mirrored)

RSPAN VLAN (the destination for the mirrored traffic)

Reflector port (the port that is connected, through the intermediate switches, to the 
destination switch)

Tx/Rx (both egress and ingress traffic must be mirrored)
