Managing Network Interfaces

Rev 4.0 User Manual 58

Field Description

Management VLAN (active when more than one

VLAN is configured).

When only a single VLAN is configured Peer-to-

Peer traffic is allowed.

Multicast peer to peer communication

• Allow: multicast/broadcast peer-to-peer traffic is

enable

• Block: multicast/broadcast peer-to-peer traffic is

blocked. Unicast peer-to-peer traffic is permitted.

Allow DHCP server on wireless

interface

DHCP server (default gateway) in the wireless interface

(not SBH) is valid. By default, this is not allowed.

Default gateway configuration

Active only when peer-to-peer traffic is blocked

Backhaul interface detection

Detection of DHCP server (default gateway)

• Auto: Detection is done automatically (by looking

for the DHCP Server / Default GW)..

• Manual: Must specify manually on which interface

resides the default gateway, and for non-

multicast traffic, if it performs proxy ARP and its

MAC address.

Multicast Traffic Policing

WBS has the ability to limit the rate of multicast (including broadcast) packets that are

forwarded between interfaces. This feature is applicable to all multicast and broadcast packets.

WBS multicast policing is done on the ingress interface. Since it affects packets forwarded to

the egress interface, the GUI configuration is indicated for the egress interface.

Specifically, if the network operator wishes to limit the amount of multicast packets that are

flooded from the wireless access network into the Ethernet backhaul network, the policing

should be marked on the Ethernet field, on all WBS in the cluster.

If the operator wished to limit the amount of multicast packets that are flooded from the

Ethernet backhaul to the wireless, the configuration should be done on the Wireless field. In

both cases the limit is determined by Kbps (kilobits per second).

ARNING

if the multicast limit is very low, i.e. most of broadcast and multicast

packets are dropped, including ARP and DHCP. This may result in difficulties to

establish any type of connection.
