Restores
the SCTP parameters to default value in HNB-GW Global configuration
instance. Default values for all parameters are as follows:
-
alpha-rto:
5 seconds
-
beta-rto:
10 seconds
-
checksum-type:
CRC32
-
max-retx init:
5 retries
-
max-retx path:
5 retries
-
max-retx assoc:
10 retries
-
max-in-strms:
4
-
max-out-strms:
4
alpha-rto alpha_rto_dur
Sets
the alpha retransmission timeout duration (in seconds) for SCTP
association between HNB and HNB-GW as an integer from 0 through
65535. A “zero” value disables the timer in this configuration.
Default: 5
beta-rto beta_rto_dur
Sets
the beta retransmission timeout duration (in seconds) for SCTP association
between HNB and HNB-GW an integer from 0 through 65535. A “zero” value
disables the timer in this configuration. Default: 10
max-retx [ init | path | assoc ] max_retry
Sets
the maximum number of retries allowed in SCTP states for SCTP association
between HNB and HNB-GW.
init: Sets
the maximum attempts allowed after T1-init timer expires. If the
T1-init timer expires then the HNB-GW retransmits INIT chunk and
re-start the T1-init timer without changing state. This is repeated
up to the configured times with this configuration. After that,
the HNB-GW aborts the initialization process. Default number of attempts max_retry for
this state is 5.
path: Sets
the maximum attempts allowed after T3-rtx timer expires. Each time
the T3-rtx timer expires on any address, or when a HEARTBEAT sent
to an idle address is not acknowledged within a RTO, the error counter
of that destination address incremented. When the value in the error
counter exceeds this protocol parameter of that HNB address, the
HNB-GW marks the destination transport address as inactive. Default
number of attempts max_retry for
this state is 5.
assoc: Sets
the maximum number of consecutive retransmissions to its peer is
allowed. If the value of this counter exceeds the limit configured with
this keyword the HNB-GW considers the peer HNB unreachable and stop
transmitting any more data to it. The SCTP association is automatically
closed when the peer endpoint becomes unreachable. Default number
of attempts max_retry for
this state is 10.
max_retry is
an integer from 1 through 255.
max-in-strms in_strms
Sets
the maximum number of inward SCTP streams allowed on HNB-GW for
an associated HNB in an SCTP association as an integer from 1 through
16. Default: 4
max-out-strms out_strms
Sets
the maximum number of outgoing SCTP streams allowed from HNB-GW
for an associated HNB in an SCTP association as an integer from
1 through 16. Default: 4
Usage:
Use this command to
configure the SCTP protocol messaging and session management parameters
in SCTP association between HNB and HNB-GW.
Example:
The following command
sets the maximum number of inward SCTP streams allowed to
4 on HNB-GW
for the SCTP association:
default max-in-strms
