7. The Peer table lists the credentials of the GRE tunnel end points. Add new table rows as

needed to add additional GRE tunnel peers.

Select + Add Row to populate the table with a maximum of two peer configurations.

8. Define the following Peer parameters:

9. Define the following Failover parameters to apply to the GRE tunnel configuration:

10. Select the OK button located to save the changes. Select Reset to revert to the last saved

configuration.

IGMP Snooping

Profile Network Configuration

The Internet Group Management Protocol (IGMP) is used for managing IP multicast group
members. The controller or service platform listens to IGMP network traffic and forwards the IGMP
multicast packets to radios on which the interested hosts are connected. On the wired side of the
network, the controller or service platform floods all the wired interfaces. This feature reduces
unnecessary flooding of multicast traffic in the network.

To define a Profile’s IGMP settings:

1. Select Configuration > Profiles > Network.

Expand the Network menu to display its submenu options.

Select IGMP Snooping.

Tag Native VLAN

Select this option to tag the native VLAN. The IEEE 802.1Q specification is supported for
tagging frames and coordinating VLANs between devices. IEEE 802.1Q adds four bytes
to each frame identifying the VLAN ID for upstream devices that the frame belongs. If
the upstream Ethernet device does not support IEEE 802.1Q tagging, it does not
interpret the tagged frames. When VLAN tagging is required between devices, both
devices must support tagging and be configured to accept tagged VLANs. When a frame
is tagged, the 12 bit frame VLAN ID is added to the 802.1Q header so upstream
Ethernet devices know which VLAN ID the frame belongs to. The device reads the 12 bit
VLAN ID and forwards the frame to the appropriate VLAN. When a frame is received with
no 802.1Q header, the upstream device classifies the frame using the default or native
VLAN assigned to the Trunk port. The native VLAN allows an Ethernet device to
associate untagged frames to a VLAN when no 802.1Q frame is included in the frame.
This feature is disabled by default.

Peer Index

Assign a numeric index to each peer to help differentiate tunnel end points.

Peer IP Address

Define the IP address of the added GRE peer to serve as a network address identifier.

Enable Failover

Select this option to periodically ping the primary gateway to assess its availability for
failover support.

Ping Interval

Set the duration between two successive pings to the gateway. Define this value in
seconds from 0 - 86,400.

Number of Retries

Set the number of retry ping opportunities before the session is terminated.
