Prioritized Parent Selection If more control is needed than the automatic algorithm allows, a priority list of parents for the RLX2 radio can be defined.With Parent Branch Length, the radio will choose its parent strictly by the number of repeaters between it and the Master radio. If Branch Length of 1 is chosen, the radio will link only to the Master radio. If Branch Length of 2 is chosen, the radio will link only to an RLX2 radio that is linked to the Master radio, and so on.With Preferred Parent, the radio will select its parent from a list of user-specified parents. Up to eight radios can be defined.  Best in List The radio will select its parent using the "Automatic Parent Selection" algorithm described above but it will limit the selection to the radios in the list. The radio in the list with the lowest cost according to the algorithm will be chosen as its parent.

 Follow List Priority

 The radio will select its parent from the list giving preference to the first entry, followed by the second entry, and so on.RLX2 radios support IGMP v1 and v2. The default operation of the RLX2 radios is to have IGMP functionality enabled, although the user can disable IGMP entirely. Additionally, the user can specify settings associated with IGMP filtering and snooping. Unknown multicast addresses can be sent to all ports (flood) or to none (filtered) by changing the IGMP Multicast Filtering option. The user can specify whether the radio will generate IGMP queries, and configure the query interval time. By RFC specification, only one device on a network should generate IGMP queries. As such, RLX2 radios will only send a query if another device has not sent a query within its Query Interval setting, even if Query Generation is enabled.

VLAN Settings 

RLX2 radios support port based VLANs. Each RLX2 can be considered to have 3 different ports or interfaces; the Ethernet interface, the local applications stack of the RLX2 itself, and the 802.11 BSS created by each RLX2 allowing client devices to associate. The VLAN settings for the Ethernet interface are settable on all RLX2 radios. The VLAN settings for the Local and SSID ports are only settable on the Master and pushed down to each Repeater associated below the Master. This allows the VLAN settings for an RLX2 bridged network rooted at a Master to have common settings for these two ports, which ensures for example, that if the Local interface is set to a management VLAN, the all Repeaters below the Master will all be accessible by a Management PC. The Ethernet ports for the Master and its associated Repeaters can be thought of as a smart switch. Transporting of tagged frames to the appropriate remote Ethernet port is automatic and does not require any settings.
