Introduction

The hardware on all multiservice switches support port-based VLANs with 
the following characteristics:

■

Frames classified as Layer 1 (port-based) when they enter the 
switch

■

Explicitly tagged VLAN packets — these are forwarded based on 
the information in the packet. 

■

Up to 1,000 VLANs — VLANs define a set of ports in a flooding 
domain. Packets that need to be flooded are sent only to ports 
participating in that VLAN.

For more information on VLANs, see

Hunt groups allow you to aggregate bandwidth from multiple ports so they 
act as one high-bandwidth switch port. Hunt groups create multi-gigabit 
pipes to transport traffic through the highest traffic areas of your network. 
You can create hunt groups that interoperate with other vendors’ equipment 
(for example, Cisco’s Etherchannel and Sun’s Quad Adapter).

For more information on hunt groups, see

Spanning tree protocol is used to prevent loops from forming in your 
network. The spanning tree algorithm creates a single path through the 
network by ensuring that if more than one path exists between two parts of a 
network, only one of these paths is used, while the others are blocked.

The P580 and P882 support common Spanning Tree and Rapid Spanning 
Tree. Rapid Spanning Tree provides faster recovery from network failures 
than common Spanning Tree provides. 

All multiservice switches support the following four Spanning Tree 
configurations:

■

IEEE 802.1D Spanning Tree

■

Per-VLAN Spanning Tree
