ONFIGURING THE

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 3-110
before 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.)
