IGMP Snooping
Internet Group Management Protocol (IGMP) is a protocol to establish and maintain multicast
group memberships to interested members. Multicasting allows a networked computer to send
content to multiple computers who have registered to receive the content. IGMP Snooping is for
listening to IGMP traffic between an IGMP host and routers in the network to maintain a map of the
links that require multicast streams. Multicast traffic is filtered out for those links which do not
require them.
To configure IGMP Snooping:
1. Select the Configuration tab from the Web UI.
2. Select Devices.
Name
Define a 31 character maximum name for this tunnel session. Each session name represents a
single data stream.
IP Address
Specify the IP address used as a tunnel source IP address. If not specified, the tunnel source IP
address is selected automatically based on the tunnel peer IP address. This address is applicable
only for initiating the tunnel. When responding to incoming tunnel create requests, the tunnel
would use the IP address received in the tunnel create request.
IP
Set the IP address of an L2TP tunnel peer. This is the peer allowed to establish the tunnel.
Local Session ID
Set the numeric identifier for the tunnel session. This is the pseudowire ID for the session. This
pseudowire ID is sent in session establishment message to the L2TP peer.
MTU
Define the session maximum transmission unit (MTU) as the size (in bytes) of the largest protocol
data unit the layer can pass between tunnel peers in this session. A larger MTU means processing
fewer packets for the same amount of data.
Remote Session ID
Use the spinner control to set the remote session ID passed in the establishment of the tunnel
session. Assign an ID from 1 - 4,294,967,295.
Encapsulation
Select either IP or UDP as the peer encapsulation protocol. The default setting is IP. UDP uses a
simple transmission model without implicit handshakes.
UDP Port
If UDP encapsulation is selected, use the spinner control to define the UDP encapsulation port. This
is the port where the L2TP service is running.
Source VLAN
Define the VLAN range (1 - 4,094) to include in the tunnel. Tunnel session data includes VLAN
tagged frames.
Native VLAN
Select this option to define the native VLAN that will not be tagged.
Cookie Size
Set the size of the cookie field within each L2TP data packet. Options include 0, 4 and 8. The
default setting is 0.
Value 1
Set the cookie value first word.
Value 2
Set the cookie value second word.
End Point
Define whether the tunnel end point is local or remote.
