milliseconds Unsigned32
When set to a non-zero value greater than
lmpCcHelloDeadIntervalNegotiated, the object overrides the
value of lmpCcHelloDeadIntervalNegotiated for a control
channel to indicate how long the device should wait (in
milliseconds) before declaring that control channel dead.
When set to a non-zero value less than or equal to
lmpCcHelloDeadIntervalNegotiated for a control channel,
this field has no effect for that control channel.
When set to zero (the default value), this field is not
used by LMP.
Use of this object is strongly discouraged because not
detecting control channel failure in a timely manner can
cause negative effects. For example, as follows.
- BeginVerify messages will continue to be retried after
lmpCcHelloDeadIntervalNegotiated has expired, which
will block anonymous verification of TELs with other
neighbors. On hardware with limited termination
capability for sending Test messages, this behaviour
might block all link verification to all neighbors, not
just anonymous verification.
- If there are multiple control channels to a neighbor
and the primary control channel fails, DC-LMP will
continue using the failed control channel to send all
message types that are not control channel specific,
rather than another control channel becoming the
primary control channel. Hence the neighbor will not
receive any of these messages.
- Hello messages, and message types that are not control
channel specific, continue to be sent over the control
channel after the lmpCcHelloDeadIntervalNegotiated has
expired. This behavior does not conform to RFC 4204.
However, this object can be set to a non-zero value when
- the local node wishes to support LMP Graceful Restart
procedures for neighbors that restart and
- LMP neighbors may take longer to restart than the
maximum possible value for the
lmpCcHelloDeadIntervalNegotiated.
The object should be set to a value that is as small as
possible because of the negative effects listed above.
This field may be changed at any time. The new value is
used the next time that the HelloDead timer is started for
each Control Channel.
