This chapter describes the procedures you can use to configure routable VLANs using Device Manager.
The Nortel Ethernet Routing Switch 5000 Series are Layer 3 (L3) switches. This means that a regular Layer 2 VLAN becomes a routable Layer 3 VLAN if an IP address and MAC address are attached to the VLAN. When routing is enabled in Layer 3 mode, every Layer 3 VLAN is capable of routing as well as carrying the management traffic. You can use any Layer 3 VLAN instead of the Management VLAN to manage the switch.
