58 Chapter 3 G.SHDSL Port Setup
Figure 28 MAC Count Filter Edit
The following table describes the labels in this screen.
3.18 IGMP Filter Profile Setup
You can use the IGMP filter profiles to control access to a service that uses a specific multicast
group (like a SIP server for example). Configure an IGMP filter profile that allows access to
that multicast group. Then assign the IGMP filter profile to DSL ports that are allowed to use
the service.
Click Port Setup in the navigation panel and then the G.SHDSL line card’s link to open the
card’s Port Setup screen. Click the IGMP Filter Profile Setup link in the SLC Port Setup
screen to open this screen.
The DEFVAL IGMP filter profile is assigned to all of the DSL ports by default. It allows a
port to join all multicast IP addresses (224.0.0.0~239.255.255.255). If you want to allow an
DSL subscriber access to only specific IGMP multicast groups, use the
IGMP Filter Profile
Setup screen to configure a different profile and then assign it to the subscriber's DSL port in
the SLC Edit Port Setup screen (see Figure 11 on page 35 ).
Table 23 MAC Count Filter Edit
LABEL DESCRIPTION
MAC Count Filter
Setup
Click this link to go to the MAC Count Filter Setup screen.
Port Setup Click this link to go to the card's Port Setup screen.
Filtering Enable Select this check box to enable MAC address count filtering on this port.
Max MAC Count Use this field to limit the number of MAC addresses that this port may dynamically
learn. For example, if you are configuring port 2 and you set this field to "5", then
only five devices with dynamically learned MAC addresses may access port 2 at
any one time. A sixth device would have to wait until one of the five learned MAC
addresses ages out.
The valid range is from “1” to “1024”.
