This design supports traffic monitoring using SPAN or RSPAN. For example, a network-analysis 
device connected to the external ports on the front of the Cisco Catalyst Blade Switch 3020 may 
capture locally mirrored traffic. Alternatively, RSPAN traffic can be carried on the Cisco Catalyst 
Blade Switch 3020 uplinks if bandwidth usage is not a concern. For the steps to configure traffic 
monitoring, refer to the “Configuration Details” section. 

Complete the following steps on the aggregate switches: 

Step 1.   VLAN configuration 

Step 2.   RPVST+ configuration 

Step 3.   Primary and secondary root configuration 

Step 4.   Configuration of port channels between aggregate switches 

Step 5.   Configuration of port channels between aggregate switches and Cisco Catalyst Blade 

Switch 3020s  

Step 6.   Trunking of port channels between aggregate switches 

Step 7.   Configuration of default gateway for each VLAN 

Complete the following steps on the Cisco Catalyst Blade Switch 3020s: 

Step 1.   VLAN configuration 

Step 2.   RPVST+ configuration 

Step 3.   Configuration of port channels between the Cisco Catalyst Blade Switch 3020s and 

aggregate switches 

Step 4.   Trunking of port channels between the Cisco Catalyst Blade Switch 3020 and aggregate 

switches 

Step 5.   Configuration of server ports on the Cisco Catalyst Blade Switch 3020 

This section describes the configuration steps required for implementing the topologies discussed 
in this guide. It discusses configurations for the following: 

● 

VLAN 

● 

RPVST+ 

● 

Inter-Switch Link (ISL) 

● 

Server port 

● 

Server default gateway 

● 

RSPAN
