• They ease the change and movement of devices on networks.

Spanning Tree
*
Protocol
(
STP
)
The switch supports the IEEE 802.1D Spanning Tree
*
Protocol
(STP), which is a bridge-based mechanism for providing fault
tolerance on networks and/or voice traffic loops due to mis-cabling.
STP enables you to implement parallel paths for network traffic, and
ensure the following:
• Redundant paths are disabled when the main paths are operational.
• Redundant paths are enabled if the main traffic paths fail.
A single spanning tree may span multiple VLANs.
For more information, refer to Chapter 7, Spanning Tree
*
Protocol.
Quality of Service (QoS)
The local management software has Policy-Based Quality of Service
(QoS) features that enable you to specify service levels for different
traffic groups. By default, all traffic is assigned the “normal” QoS
policy profile. If needed, you can create other QoS policies and apply
them to different traffic types so that they have different guaranteed
minimum bandwidth, maximum bandwidth, and priority.
For more information, refer to Chapter 8, Quality of Service.
Unicast Routing
The switch can route IP or IPX
*
traffic between the VLANs that are
configured as virtual router interfaces. Both dynamic and static IP
routes are maintained in the routing table. The following routing
protocols are supported:
• RIP version 1
• RIP version 2
• OSPF
• IPX/RIP
For more information, refer to Chapter 10, IP Unicast Routing, or
Chapter 13, IPX Routing.
