(This implies that the network management subsystem should clean up any related entry in the mplsLdpPeerTable. This further implies that a 'tear-down' for that session is issued and the session and all information related to that session cease to exist). At this point the operator is able to change values which are related to this entity.

According to the LDP Specification [RFC3036] a value of 255 or less specifies the default maximum length of 4096 octets, this is why the value of this object starts at 256. The operator should explicitly choose the default value (i.e., 4096), or some other value. The receiving LSR MUST calculate the maximum PDU length for the session by using the smaller of its and its peer's proposals for Max PDU Length." REFERENCE "RFC3036, LDP Specification, Section 3.5.3.

The Hello Hold time in seconds.
An LSR maintains a record of Hellos received from potential peers. This object represents the Hold Time in the Common Hello Parameters TLV of the Hello Message. A value of 0 is a default value and should be interpretted in conjunction with the mplsLdpEntityTargetPeer object. If the value of this object is 0: if the value of the mplsLdpEntityTargetPeer object is false(2), then this specifies that the Hold Time's actual default value is 15 seconds (i.e., the default Hold time for Link Hellos is 15 seconds). Otherwise if the value of the mplsLdpEntityTargetPeer object is true(1), then this specifies that the Hold Time's actual default value is 45 seconds (i.e., the default Hold time for Targeted Hellos is 45 seconds). A value of 65535 means infinite (i.e., wait forever). All other values represent the amount of time in seconds to wait for a Hello Message.

The notification is used to notify an operator when this Entity and its Peer are possibly engaged in an endless sequence of messages as each NAKs the other's
Initialization messages with Error Notification messages. Setting this threshold which triggers the notification is one way to notify the operator. The notification should be generated each time this threshold is exceeded and for every subsequent Initialization message which is NAK'd with an Error Notification message after this threshold is exceeded. A value of 0 (zero) for this object indicates that the threshold is infinity, thus the SNMP notification will never be generated."
