Help MLP With all the command ppp multilink
Determine the edge at which the next b-channel ought to start out carrying info Together with the dialer load-threshold command.
Enable’s say you required the second b-channel to start out carrying knowledge when the primary channel reaches seventy five% of capability. It could make sense that the command to do so would be dialer load-threshold 75… nonetheless it’s not.

R1(config-if)#ppp multilink
R1(config-if)#dialer load-threshold ?
