8. 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.
9. Define the following Peer parameters:
10. Define or override the following Failover parameters to apply to the GRE tunnel configuration:
Select the OK button to save the changes and overrides to the GRE configuration. Select Reset to
revert to the last saved configuration.
Overriding a Profile’s IGMP Snooping Configuration
Overriding a Profile’s 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 Devices from the Configuration tab.
Native VLAN Set a numerical VLAN ID (1 - 4094) for the native VLAN. The native VLAN allows an
Ethernet device to associate untagged frames to a VLAN when no 802.1Q frame is
included in the frame. Additionally, the native VLAN is the VLAN untagged traffic is
directed over when using a port in trunk mode.
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. If the
primary gateway is unreachable.
Ping Interval Set the duration between two successive pings to the gateway. Define this value in
seconds from 1 - 21,600.
Number of Retries Set the number of ping retries (from 1 - 63) when no response is received before the
session is terminated.
