The Cisco Catalyst Blade Switch 3020 contains an additional Fast Ethernet port, which connects to the HP
The Cisco Catalyst Blade Switch 3020 supports multiple switched virtual interfaces (SVIs) to be active at the same time; however, it does not perform any routing functions between SVIs. By default, the SVI is created as VLAN 1 and enabled during the setup phase of the installation. The VLAN is often referred to as the “management VLAN”. Cisco recommends that the user change the management VLAN to something other than VLAN 1. Therefore, it is important to create an SVI with another VLAN and allow this VLAN on the external
By default, the Cisco Catalyst Blade Switch 3020 provides no routing functions and can have only one default gateway defined. Even though the Fa0 interface is called “routed”, it cannot route user traffic. Therefore, if you enable multiple SVIs or enable the Fast Ethernet port, you will not be able to access all these interfaces from other subnets. The recent migration (12.2(22)SE) of the Cisco Catalyst Blade Switch 3020 from the LANBase image to IP Base provides basic Layer 3 routing (RIP and Static Routing and EIRGP Stub).
