Configure Radio Traffic Aggregation Mode. When the 'normal' mode aggregation is configured, Ethernet frames are distributed to the multiple radio links based on usual Link aggregation behaviour. when the 'phyMode' mode, Ethernet frames are distributed to the multiple radio links based on the ratio for the radio link speed. 'phyMode' must be configured to the modem cards which are belonging to the same radio traffic aggregation group. And 'phyMode' must be configured to continuous 2 slots (lower slot is odd number). If 'phyMode' is configured to the single modem or 3 or more slots, the agent will reject the request. 'phyAdvancedMode' must be configured to the modem cards which are belonging to the same radio traffic aggregation group. And 'phyAdvancedMode' must be configured to continuous 3 or more slots (lower slot is odd number). If 'phyAdvancedMode' is configured to the one or 2 modems, the agent will reject the request. 'phyAdvancedMode' is valid for iPASO VR 10 only.
