How does RSPAN work?

RSPAN works by mirroring the traffic from the source ports of an RSPAN session onto a VLAN that is dedicated for the RSPAN session. This VLAN is then trunked to other switches, allowing the RSPAN session traffic to be transported across multiple switches.

Destination (SPAN) port: A port that monitors source ports. This is usually the point to which a network analyser is connected. Remote SPAN (RSPAN): When Source ports are not located on the same switch as the Destination port.

What is Rspan port?

The Remote Switched Port Analyzer (RSPAN) enables you to monitor traffic on one switch through a device on another switch and then send the monitored traffic to one or more destinations.

What is reflector port in Rspan?

The reflector port is the mechanism that copies packets onto an RSPAN VLAN. The reflector port forwards only the traffic from the RSPAN source session with which it is affiliated. RSPAN extends SPAN by enabling remote monitoring of multiple switches across your network.

What is difference between Span and Rspan?

When you use a destination interface on the same switch as your switch we call it SPAN, when the destination is a remote interface on another switch we call it RSPAN (Remote SPAN). When using RSPAN you need to use a VLAN for your RSPAN traffic so that traffic can travel from the source switch to the destination switch.

What is remote span?

A remote SPAN (RSPAN) is sourced in the same manner as a traditional SPAN, either from individual ports or all ports in a VLAN. An RSPAN consumes one SPAN session in the same way that a local SPAN does, however, the RSPAN uses a VLAN for a destination instead of an interface.

How many span sessions can I configure in a Catalyst 4500 switch?

You can configure (and store in NVRAM) up to five SPAN sessions in a Catalyst 4500 series switch. The five sessions can be split any way between SPAN, RSPAN source, and RSPAN destination sessions. The following sections describe how to configure SPAN. SPAN selects network traffic for analysis by a SwitchProbe device or other RMON probe.

How do I check the status of a span or RSPAN session?

The “Status” field in the show span and show rspan commands displays the operational status of a SPAN or RSPAN session. After the system is on, a SPAN or RSPAN destination session remains inactive until the destination port is operational.
