sctp
To enter the Stream Control Transmission Protocol (SCTP) configuration, use the sctp command in IDSN User Adaptation Layer (IUA) configuration mode. To disable, use the no form of this command.
sctp [ [t1-init milliseconds] [t3-rtx-min seconds] [t3-rtx-max milliseconds] [startup-rtx number] [assoc-rtx number] [path-rtx number]]
no sctp
Syntax Description
t1 -init milliseconds |
Timer T1 initiation value in milliseconds. Valid values are from 1000 to 60000. The t1-init configurable option applies only during the creation of an SCTP instance. |
t3 -rtx -min seconds |
Timer T3 retransmission minimum timeout in seconds. Valid values are from 1 to 300. |
t3 -rtx -max milliseconds |
Timer T3 retransmission maximum timeout in milliseconds. Valid values are from 1000 to 60000. |
startup -rtx number |
Maximum startup retransmissions. The startup-rtx configurable option applies only during the creation of an SCTP instance. Valid values are from 2 to 20. |
assoc -rtx number |
Maximum association retransmissions. Valid values are from 2 to 20. |
path-rtx number |
Maximum path retransmissions. Valid values are from 2 to 20. |
Command Default
SCTP configuration commands cannot be entered.

Usage Guidelines
To enter SCTP configuration commands, you must first enter IUA configuration mode and then enter sctp at the Router(config-iua)# prompt to enter SCTP configuration mode.
Examples
The following example shows how to enter IUA configuration mode:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# iua
Router(config-iua)#
The following is an example of how to set failover time (in milliseconds) between 1 and 10 seconds as part of SCTP configuration of the T1 initiation timer. This example uses the lowest failover timer value allowed (1 second):
Router(config-iua)# as as5400-3 fail-over 1000
The following is an example of how to set SCTP maximum startup retransmission interval. This example uses the maximum startup retransmission interval value allowed:
Router(config-iua)# as as5400-3 sctp-startup 20
The following is an example of how to configure the number of SCTP streams for this AS. This example uses the maximum SCTP streams allowed:
Router(config-iua)# as as5400-3 sctp-streams 57
The following is an example of how to configure the SCTP T1 initiation timer (in milliseconds). This example uses the maximum timer value allowed:
Router(config-iua)# as as5400-3 sctp-t1init 60000
