Syntax
sctp heart-beat-timeout dur
{ default | no } sctp heart-beat-timeout
no
Disables the heartbeat timer configuration for SCTP over IuH in HNB-GW service instance.
default
Restores the default time out value for heartbeat timer to 30 seconds.
dur
Sets the heartbeat timer timeout duration (in seconds) after which the next heartbeat command is sent to HNB
from HNB-GW in SCTP over an IuH interface. In an HNB de-registration scenario, the HNB-GW waits for
configured amount time before initiating the procedure to clear the SCTP association.

dur
is an integer from 1 through 300. Default: 30
Usage
Use this command to configure the minimum duration value before retransmitting the HEARTBEAT chunk
to HNB from HNB-GW in SCTP transmission. By default HNB-GW monitors the reachability of the idle
HNBs by sending a HEARTBEAT chunk periodically to the HNB address.
Each time the HEARTBEAT timer expires on any address, or when a HEARTBEAT sent to an idle address is
not acknowledged within a Retransmission Timeout duration, the error counter of that HNB incremented.
When the value in the error counter exceeds the protocol parameter for maximum retransmission for that
destination address, the HNB-GW mark the destination HNB as inactive and a notification is sent to the upper
layer.
