ZyXEL Communications P-660H-TX - Manual (Page 68)

P-660H-Tx v2 Support Notes
needs to be forwarded. At start up, the P-660H-Tx v2 queries all directly
connected networks to gather group membership.
After that, the P-660H-Tx v2 updates the information by periodic queries. The
P-660H-Tx v2 implementation of IGMP is also compatible with version 1. The
multicast setting can be turned on or off on Ethernet and remote nodes.
• IP Multicast Setup
(1) Enable IGMP in P-660H-Tx v2's LAN in Web Configurator, Advanced
Setup, Network -> LAN -> IP -> Advanced Setup.
(2) Enable IGMP in P-660H-Tx v2's remote node in Web Configurator,
Advanced Setup, Network -> Remote Node -> Edit -> Multicast.
Key Settings:
Multicast IGMP-v1 for IGMP version 1, IGMP-v2 for IGMP version 2.
13. Using Bandwidth Management
• Why Bandwidth Management (BWM)?
Nowadays, we have many different traffic types for Internet applications. Some
traffic may consume high bandwidth, such as FTP (File Transfer Protocol).
Some other traffic may not require high bandwidth, but they require stable
supply of bandwidth, such as VoIP traffic. The VoIP quality would not be good,
if all of the outgoing bandwidth is occupied via FTP. Additionally, chances are
that you would like to grant higher bandwidth for some body specially who is
using specific IP address in your network. All of these are reasons why we
need bandwidth management.
• Using BWM
Setp 1: Go to Web Configurator, Advanced Setup, Advanced -> Bandwidth
MGMT->Summary, activate bandwidth management on the interface you
would like to manage. We enable the BWM function on WAN interface in this
example.
Enter the total speed for this interface that you want to allocate using
bandwidth management. This appears as the bandwidth budget of the
interface’s root class.
Select how you want the bandwidth to be allocated. Priority-Based means
bandwidth is allocated via priority, so the traffic with highest priority would be
served first, then the second priority is served secondly and so on. If
