C H A P T E R 1 Overview
IP Multicast Routing
The switch can use IP multicasting to allow a single IP host to
transmit a packet to a group of IP hosts. The 480T switch supports
multicast routes that are learned by way of the Distance Vector
Multicast Routing Protocol (DVMRP) or Protocol Independent
Multicast-Dense Mode (PIM-DM).
For more information, refer to Chapter 12, IP Multicast Routing.
Load Sharing
Load sharing allows you to increase bandwidth and resiliency by
using a group of ports to carry traffic in parallel between systems. The
sharing algorithm allows the switch to use multiple ports as a single
logical port. For example, VLANs see the load-sharing group as a
single virtual port. The algorithm also guarantees packet sequencing
between clients.
For information, refer to Chapter 4, Load Sharing.
Software Licensing
Intel 480T switches have capabilities that are enabled by using a
license key. Keys are typically unique to the switch, and are not
transferable. Keys are stored in NVRAM and, once entered, persist
through reboots, software upgrades, and reconfigurations. The
following sections describe the features that are associated with
license keys.
Router Licensing
The 480T switch supports software licensing for different levels of
router functionality. In firmware version 6.0 and above, routing
protocol support is separated into two sets: Basic and Full Layer 3.
Basic is a subset of Full Layer 3.
