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.

The interface VLAN command is executed in the Global Conﬁguration

command mode.

ip address command
