CONFIGURING THE SWITCH

Basic IP Interface Configuration

To allow routing between different IP subnets, you must enable IP Routing as described in this section. You also need to you define a VLAN for each IP subnet that will be connected directly to this switch. Note that you must first create a VLAN as described under “Creating VLANs” on page 3-110before configuring the corresponding subnet. Remember that if you need to manage the switch in-band then you must define the IP subnet address for at least one VLAN.

Command Attributes

•IP Routing Status – Configures the switch to operate as a Layer 2 switch or as a multilayer routing switch. (Options: Disable this field to restrict operation to Layer 2 switching; enable it to allow multilayer operation at either Layer 2 or 3 as required.)

-This command affects both static and dynamic unicast routing.

-If IP routing is enabled, all IP packets are routed using either static routing or dynamic routing via RIP or OSPF, and other packets for all non-IP protocols (e.g., NetBuei, NetWare or AppleTalk) are switched based on MAC addresses. If IP routing is disabled, all packets are switched, with filtering and forwarding decisions based strictly on MAC addresses.

•Default Gateway – The routing device to which the switch will pass packets for all unknown subnets; i.e., packets that do not match any routing table entry. (Valid IP addresses consist of four numbers, 0 to 255, separated by periods.)
