threshold parameter allows the loadsharing group to be declared down if the number of paths
drops equal to or lower than the threshold value. The ‘lag-emulation’ context provides access to
conventional LAG parameters such as the adapt-qos mode (link or distributed bandwidth
distribution) and per-fp-ing-queuing to ensure that only one ingress queue is instantiated for every
physical link supported on the same FP complex.
A typical use case for LAG emulation is to allow unprotected Ethernet services to capitalize on the
LAG capability. RSTP and MSTP can also be used to network VPLS or B-VPLS over the
Ethernet tunnels.
