DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch
Source switch –
The switch which has the monitored ports or VLANs on it is the source switch. All packets on the source ports or
VLANs are copied and sent to the destination switch. When the mirrored packets are sent out from the source switch, an RSPAN
VLAN tag is added to every packet. The incoming port on the source switch for the mirrored packets is referred to as the
source
port
.
Intermediate switch
The function of the intermediate switch is to mirror traffic flowing in the RSPAN VLAN toward the
RSAPN destination. A switch can be have the role of an RSAPN VLAN intermediate switch as well as the role of source switch
for another RSPAN VLAN.
Destination Switch
The port which is directly connected to a network analyzer, other monitoring, or security device is called the
destination port
. The switch which has a destination port is called the
destination switch
. The destination switch removes the
RSPAN VLAN tags from the mirrored packets when the destination port is an untagged port in the RSPAN VLAN. If the
destination port is a tagged port, the tags will be reserved.
RSPAN State Settings
This window allows the user to enable or disable the RSPAN settings on the Switch. The purpose of the RSPAN function is to
mirror the packets to the remote switch. The packet travels from the switch where the monitored packet is received, through the
intermediate switch, then to the switch where the sniffer is attached. The first switch is also named the source switch.
