0 = Strict Priority scheduling between LAN Queues within the same LAN Queue Group (enabled for all 4
LAN Queue Groups) and the WAN Insert Channel
1 = Weighted Round Robin (WRR) Scheduling between LAN Queues within LAN Queue Group #1
and with the WAN Insert Channel. When LQSM = 1, the other 3 LAN Queue Groups (12 LAN Queues)
are not allowed. WRR Scheduling mode is only available in Forwarding Mode 2, with a single LAN
Port enabled.
