Layer 3 routable VLANs

The Nortel Ethernet Routing Switch 5500 Series are Layer 3 (L3) switches. This means that a regular L2 VLAN becomes a routable L3 VLAN if an IP address and MAC address are attached to the VLAN. When routing is enabled in L3 mode, every L3 VLAN is capable of routing as well as carrying the management traffic. The user can use any L3 VLAN instead of the Management VLAN to manage the switch.

This section covers the commands that are used to set up and configure routable VLANs.

interface vlan command

The interface vlan command only takes to the interface config mode. The ip routing command in the interface-config mode enables routing on a specific vlan.

The syntax for the interface VLAN command is:

interface vlan <1 - 4094>

The interface VLAN command is executed in the Global Configuration command mode.

ip address command

The ip address command enables routing on a VLAN.

The syntax for the ip address command is:

ip address <A.B.C.D> <W.X.Y.Z> [<1 - 256>] [secondary]

The ip address command is executed in the Interface Configuration command mode.

The following table describes the parameters for this command.
