Chapter 61 - Remote Switching Port Analyzer (RSPAN) Chapter Overview The source switch copies (or mirrors) packets received or sent (or both) on source ports (P1) to the destination port (P12). The traffic mirrored toward to the destination port will add an RSPAN tag. The destination port (P12) used to transmit the monitor packets and the RSPAN VLAN used to tunnel the monitored packets to the remote site. The destination port does not need to be the member port of the RSPAN VLAN. The destination port can be either a physical port or a port channel. The intermediate switch uses VLAN flooding technology to transmit the traffic flowing on RSPAN VLAN toward to destination port (P11). For the intermediate switch involved in a RSPAN session, the port(P1) that the monitored packet arrives from and the port(P11) that the monitored packets will be sent out need to configured as tag member port of the RSPAN VLAN. The destination switch uses VLAN flooding technology to transmit the traffic flowing on RSPAN VLAN toward to destination port(P2) specified by administrator, the RSAPN VAN tag will be removed according to 802.1Q VLAN egress rules. Operation Concepts There are three roles for switches in RSPAN. 1.Source Switch: The switch which has the monitored ports on can be the source switch. All packets on the source ports are copied and sent to the destination switch. When the mirrored packets are sent out from source switch, an RSPAN VLAN tag is added to every packet. The incoming port on source switch for the mirrored packets is a source port. The outgoing port on source switch for the mirrored packets is source target port. Mirrored traffic has 3 types: i. Receive (Rx) - The goal of receive (or ingress) RSPAN is to monitor as much as possible all the packets received by the source interface before any modification or processing is performed by the switch. A copy of each packet received by the source is sent to the destination port for that remote source session. ii. Transmit (Tx) - The goal of transmit (or egress) SPAN is to monitor as much as possible all the packets sent by the source interface after all modification and processing is performed by the switch. iii. Both - In a Monitor session, you can also monitor a port for both received and sent packets. This is the default. DGS-6600 Configuration Guide 591

The destination port (P12) used to transmit the monitor packets and the RSPAN VLAN used to

For the intermediate switch involved in a RSPAN session, the port(P1) that the monitored packet

The destination switch uses VLAN flooding technology to transmit the traffic flowing on RSPAN

Operation Concepts
There are three roles for switches in RSPAN.
1.Source Switch:
The switch which has the monitored ports on can be the source switch. All packets on the source
ports are copied and sent to the destination switch. When the mirrored packets are sent out from
source switch, an RSPAN VLAN tag is added to every packet. The incoming port on source switch
for the mirrored packets is a source port. The outgoing port on source switch for the mirrored
packets is source target port.
Mirrored traffic has 3 types:
i. Receive (Rx) - The goal of receive (or ingress) RSPAN is to monitor as much as possible all the
packets received by the source interface before any modification or processing is performed by the
switch. A copy of each packet received by the source is sent to the destination port for that remote
source session.
ii. Transmit (Tx) - The goal of transmit (or egress) SPAN is to monitor as much as possible all the
packets sent by the source interface after all modification and processing is performed by the switch.
iii. Both - In a Monitor session, you can also monitor a port for both received and sent packets. This
is the default.
