Configuring RSPAN Chapter 25 Configuring SPAN and RSPAN RSPAN Configuration Examples The following sections have several examples on how to configure RSPAN. Configuring a Single RSPAN Session This example shows how to configure a single RSPAN session. Figure 25-3 shows an RSPAN configuration; see Table 25-1 for the necessary commands to configure this RSPAN session. Table 25-1 assumes that you have already set up RSPAN VLAN 901 for this session on all the switches using the set vlan vlan_num 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 25-1, the RSPAN session may be disabled in Switch A or B or both without modifying the configuration in Switch C or Switch D.

Use Figure 25-3 for reference; see Table 25-2 for the necessary commands to disable an RSPAN session and to add or remove source ports from an RSPAN session. 25-14 Software Configuration Guide-Catalyst 4000 Family, Catalyst 2948G, Catalyst 2980G, Releases 6.3 and 6.4 78-12647-02
