Cisco Cisco IOS Software Release 12.4(22)XR

Router(config-ipc-protocol-sctp)# local-port 

Defines the local SCTP port number to use for 
communication with the redundant peer and enables 
IPC transport-SCTP local configuration mode. 

Valid port numbers range from 1 to 65535. There is no 
default value. 

The local port number must be identical to the 
remote port number on the peer router.

Router(config-ipc-protocol-sctp)# unit1-port port_num

If autosynchronization feature is enabled, configure 
the SCTP port. 

Router(config-ipc-local-sctp)# local ip ip_addr

Defines the local IP address that communicates with 
the redundant peer. The local IP address must match 
the remote IP address on the peer router. 

Router(config-ipc-unit1-sctp)# unit1-ip ip_addr

Represents the IP address that communicates with the 
redundant pair, if the autosynchronization feature is 
enabled. 

Router(config-ipc-local-sctp)# keepalive [period 

[retries]]

Enables keepalive packets and specifies the number of 
times that the Cisco IOS software tries to send 
keepalive packets with a response before bringing 
down the interface or tunnel protocol for a specific 
interface.

Valid value for period is an integer value in seconds 
great than 0. The default is 10. Valid value for retries 
is an integer value greater than one and less than 355. 
The default is the previously used value or 5 if there 
was no value previously specified.

Router(config-ipc-local-sctp)# retransmit-timeout interval

Configures the message retransmission time. 

Valid range is 300 to 60000 milliseconds. The 
minimum default is 1000. The maximum default is 
60000.

Router(config-ipc-local-sctp)# path-retransmit number

Configures the maximum number of keep-alive retries 
before the corresponding destination address is 
marked inactive. 

Valid range is 2 to 10. The default is 5.

Router(config-ipc-local-sctp)# assoc-retransmit number

Defines the maximum number of retransmissions over 
all destination addresses before an association is 
declared failed. 

Valid range is 2 to 20. The default is 10.

Router(config-ipc-local-sctp)# exit

Exits IPC transport - SCTP local configuration mode.
