16 CHAPTER 1: SWITCH FEATURES OVERVIEW
■ LACP automatic aggregations — that is, LACP enabled on all ports
and the aggregated links created automatically. The aggregated
link should be enabled and Spanning Tree Protocol enabled.
Parameters such as VLANs and Fast Start may be set up as required.
For further information about LACP, see Chapter 2
“Optimizing
Bandwidth”.
■ When restoring a configuration onto a unit over an aggregated link,
communication with that unit may be lost because the restore
operation disables the aggregated link ports. Communication over the
aggregated links is re-established when the restore operation has
been completed.
For detailed descriptions of the Configuration Save and Restore Web
interface operations and Command Line Interface (CLI) commands, please
refer to the Management Interface Reference Guide supplied in HTML
format on the CD-ROM that accompanies your Switch.
Multicast Filtering Multicast filtering allows the Switch to forward multicast traffic to only
the endstations that are part of a predefined multicast group, rather than
broadcasting the traffic to the whole network.
The multicast filtering system supported by your Switch uses IGMP
(Internet Group Management Protocol) snooping to detect the
endstations in each multicast group to which multicast traffic should be
forwarded.
For more information about multicast filtering, see Chapter 3
“Using
Multicast Filtering”.
Rapid Spanning Tree
Protocol
Rapid Spanning Tree Protocol (RSTP) is a bridge-based systems that
makes your network more resilient to link failure and also provides
protection from network loops — one of the major causes of broadcast
storms.
RSTP allows you to implement alternative paths for network traffic in the
event of path failure and uses a loop-detection process to:
■ Discover the efficiency of each path.
■ Enable the most efficient path.
■ Disable the less efficient paths.
