RSPAN Configuration Examples
These sections describe how to configure RSPAN:
• Configuring a Single RSPAN Session, page 49-15
• Modifying an Active RSPAN Session, page 49-16
• Adding the RSPAN Source Ports in Intermediate Switches, page 49-17
• Configuring Multiple RSPAN Sessions, page 49-17
• Adding Multiple Network Analyzers to an RSPAN Session, page 49-19
Configuring a Single RSPAN Session
This example shows how to configure a single RSPAN session. Figure 49-3 shows an RSPAN
configuration; see Table 49-2 for the commands to configure this RSPAN session. Table 49-2 assumes
that you have already set up RSPAN VLAN 901 for this session on all the switches using the set vlan
vlan rspan command. With VTP enabled in the network, you can create the RSPAN VLAN in one switch
and VTP propagates it to the other switches in the VTP domain. Note that in the configuration example
shown in Table 49-2, the RSPAN session may be disabled in Switch A or B or both without modifying
the configuration in Switch C or Switch D.
