sctp through show ip sctp statistics

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.

Command Modes

Modification

12.2(15)T

This command was introduced on the Cisco 2420, Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series; and Cisco AS5300, Cisco AS5350, Cisco AS5400, and Cisco AS5850 network access server (NAS) platforms.

12.4(15)T

This command was moved to the Cisco IOS IP Application Services Command Reference.

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:

Table 1 show debugging Field Descriptions

Field

Description

OPTS 4

Bytes of TCP expressed as a number. In this case, the bytes are 4.

ECE

Echo congestion experience.

CWR

Congestion window reduced.

SYN

Synchronize connections--Request to synchronize sequence numbers, used when a TCP connection is being opened.

WIN 4128

Advertised window size, in bytes. In this case, the bytes are 4128.

cwnd

Congestion window (cwnd)--Indicates that the window size has changed.

ssthresh

Slow-start threshold (ssthresh)--Variable used by TCP to determine whether or not to use slow-start or congestion avoidance.

usergroup

show interface mac

To display MAC accounting information for interfaces configured for MAC accounting, use the show interface mac command in user EXEC or privileged EXEC mode.

show interface [ type number ] mac

Syntax Description

type

(Optional) Interface type supported on your router.

number

(Optional) Port number of the interface. The syntax varies depending on the type of router. For example, on a Cisco 7500 series router the syntax is 0/0/0, where 0 represents the slot, port adapter, and port number (the slash marks are required). Refer to the appropriate hardware manual for numbering information.

12.2SX

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

The show interface mac command displays information for one interface, when specified, or all interfaces configured for MAC accounting.

For incoming packets on the interface, the accounting statistics are gathered before the committed access rate (CAR)/distributed committed access rate (DCAR) functionality is performed on the packet. For outgoing packets on the interface, the accounting statistics are gathered after the CAR output, and before DCAR output or distributed weighted random early detection (DWRED) or distributed weighted fair queuing (DWFQ) functionality is performed on the packet.

Therefore, if DCAR or DWRED is performed on the interface and packets are dropped, the dropped packets are still counted in the show interface mac command.

The maximum number of MAC addresses that can be stored for the input and output addresses is 512 each. After the maximum is reached, subsequent MAC addresses are ignored.

To clear the accounting statistics, use the clear counter EXEC command. To configure an interface for IP accounting based on the MAC address, use the ip accounting mac-address interface configuration command.

Examples

The following is sample output from the show interface mac command:

Router# show interface ethernet 0/1/1 mac
Ethernet0/1/1 
  Input  (511 free)
    0007.f618.4449(228):  4 packets, 456 bytes, last: 2684ms ago

  Output  (511 free)

The show ip sctp association parameters command provides information to determine the stability of SCTP associations, dynamically calculated statistics about destinations, and values to assess network congestion. This command also displays parameter values for the specified association.

This command requires an association identifier. Association identifiers can be obtained from the output of the show ip sctp association list command.

Many parameters are defined for each association. Some are configured parameters, and others are calculated. Three main groupings of parameters are displayed by this command:

  • Association configuration parameters
  • Destination address parameters
  • Association boundary parameters

The association configuration section displays information similar to that in the show ip sctp association list command, including association identifiers, state, and local and remote port and address information. The current primary destination is also displayed.

12.4(15)T

This command was moved to the Cisco IOS IP Application Services Command Reference.

Usage Guidelines

This command displays information for each of the currently configured instances. The instance number, local port, and address information are displayed. The instance state is either available or deletion pending. An instance enters the deletion pending state when a request is made to delete it but there are currently established associations for that instance. The instance cannot be deleted immediately and instead enters the pending state. No new associations are allowed in this instance, and when the last association is terminated or fails, the instance is deleted.

The default inbound and outbound stream numbers are used for establishing incoming associations, and the maximum number of associations allowed for this instance is shown. Then a snapshot of each existing association is shown, if any exists.

Effective with Cisco IOS Release 12.4(11)T, if you enter the show ip sctp instances command, you must type the complete word instances in the command syntax.

Examples

The following sample output shows available IP SCTP instances. In this example, two current instances are active and available. The first is using local port 8989, and the second is using 9191. Instance identifier 0 has three current associations, and instance identifier 1 has no current associations.

Router# show ip sctp instances

*** SCTP Instances ****
