Filtering” function.

3.2.3.1 IGMP Snooping

“IGMP” stands for “Internet Group Management Protocol”. IGMP allows hosts and routers to build multicast group memberships. IGMP snooping presents the process of IGMP network traffic listening. With this feature, VDSL2 IP DSLAM is able to listen to IGMP conversation between hosts and routers. The switch is able to maintain a relation map of links and IP multicast streams.

The following settings are needed in order to allow IGMP snooping work

3.2.4.1 Spanning Tree

Spanning Tree (also known as, STP) is a network protocol which is defined by IEEE 802.1 D standards for preventing bridge loops and broadcast radiation. In addition, STP allows redundant links to provide automatic backups. Most commonly known STP algorithms are STP (Spanning Tree Protocol), RSTP (Rapid Spanning Tree Protocol), and MSTP (Multiple Spanning Tree Protocol). This VDSL2 IP DSLAM supports both STP and MSTP. In addition, in this

3.2.7 DHCP Relay & Opt.82

“DHCP” stands for “Dynamic Host Configuration Protocol”, which is a network protocol that is for configuring network devices dynamically so these devices can communicate on an IP network. It is a service that runs at the application layer of TCP/IP protocol stack to assign IP addresses to its clients dynamically.

“DHCP Relay” will forward DHCP broadcasts to multiple DHCP servers in

3.2.7.2 DHCP Option 82

3.2.7.3 DHCP Relay

different subnets using unicasts. By doing so, DHCP clients on subnets not directly served by DHCP servers can communicate with DHCP servers. In addition, “DHCP Relay Information Options 82”, is defined in RFC 3046 and RFC 3993, allows a DHCP Relay agent to insert circuit specific information to a request which is forwarded to a DHCP server.

Users are allowed to enable or disable DHCP Option 82 by choosing the options in the dropdown menu. To setup DHCP Option 82 for this switch, users are required to enable this option first.

DHCP Relay is for enabling or disabling DHCP Relay function.

Once a MAC address is stored in the MAC address table, it stays in until it is aged out. When an “opening” is available, the switch stored the first new MAC address it sees in that opening. All packets from MAC addresses not in the MAC address table should be blocked. Two sections are in MAC Limit page:

Users are able to setup MAC limit rules for each port in this section by providing the information as the followings:

This section allows users to review the status of ports and MAC limits.

o Server Port: the UDP port number used by the authentication server

o Accounting Port: the UDP port number used by the authentication

infrastructures in order to provide a means of authenticating and authorizing devices attached to a LAN port that has point-to-point connection characteristics, and of preventing access to that port in cases in which the authentication and authorization process fails.

Note: The default 802.1x setup is disabled, hence, users will not be able to see “802.1x Configuration” page as showed above. To enable 802.1x, go to “Administration  Switch setting  Misc Configs” page to enable the 802.1x protocol field. After enable the function, the 802.1x configuration page will be shown up.

Three sections are in 802.1x configuration function:

This switch provides quality of service (QoS) to prioritize the packet forwarding when traffic congestion happens. This switch supports two QoS functions: portbased (4-level output queue) and 802.1p (8-level priority to 4-level queue mapping). In addition, Strict and weight Round Robin (WRR) QoS modes are supported.
