Priority of Heartbeat Poll Messages

When you select SMDS on a circuit, the router automatically assigns the highest

priority to heartbeat poll and LMI messages that it sends to the DSU/CSU. The

heartbeat poll and LMI messages must have priority over other data to ensure that

during heavy trafﬁc conditions, the link stays up and allows these messages to get

through to the DSU/CSU.

Note: SMDS does not support OSI.
