Description: The auto-partition algorithm protects the network from certain fault conditions which can halt all LAN communications. A media short or break, a faulty connector, or faulty or missing media termination, are examples of such conditions. If a repeater detects such faults on any of its ports, it isolates the faulty segment from the network.

A repeater does not respond to input received from an auto-partitioned port, except to determine if the fault condition has been removed. A repeater continues to transmit data to an auto-partitioned port.

Setting this object to standard(1) causes the repeater to implement the IEEE 802.3 standard auto-partitioning algorithm. If the repeater detects any of the following conditions on a given port, this algorithm isolates that port from the network.

1. Excessive length collision 2. Excessive number of consecutive collisions

Setting this object to enhanced(2) causes the repeater to implement an augmented auto-partitioning algorithm. This option protects the LAN from a greater range of fault conditions. If the repeater detects any of the following conditions on a given port, this algorithm isolates that port from the network.

1. Excessive length collision 2. Excessive number of consecutive collisions 3. No receive activity during transmission (no carrier loop back) 4. Excessive length input message (jabber) 5. Transmit carrier drop (one or more lapses in the input message during a single output message without a collision) 6. Internal detectable port failures

Some implementations may not support setting this object to all defined enumerated values. A badValue error is returned if an attempt is made to set this object to an unsupported value.

Note: The state of this object is preserved when the repeater undergoes a power-up reset.
