What is mlpppLargeBufSize?

This OID sets the size, in bytes, of each large buffer used by the Multilink PPP stack, defaulting to 1600 and normally matched to the operating system's own large buffer size. The MIB warns not to change this without vendor supervision, since it depends on the amount of RAM available on the system.
