CSCF Access Profile Configuration Mode Commands

The Access Profile Configuration Mode is used to set commands supporting the use of signaling compression, authentication, and SIP timers for subscribers accessing the system from varying network types.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

access-security-type

Sets the type of access security for a P-CSCF/A-BG.

Platform:

ASR 5000

Product:

SCM (P-CSCF, A-BG)


Privilege:

Administrator


Syntax 
[ no ] access-security-type
ipsec-3gpp-cscf
no

Disables the selected access security type.

ipsec-3gpp-cscf

Security mechanism 3GPP/3GPP2 IPSec.


Usage:

Use this command to enable or disable an access security type for a P-CSCF or A-BG.


Example:
Enables 3GPP/3GPP2 IPSec access security on P-CSCF or A-BG:
access-security-type
ipsec-3gpp-cscf
Disables 3GPP/3GPP2 IPSec access security on P-CSCF or A-BG:
no access-security-type
ipsec-3gpp-cscf
authentication

Sets the authentication method to use for subscribers using this access profile.

Platform:

ASR 5000

Product:

SCM (P-CSCF, A-BG)


Privilege:

Administrator


Syntax 
[ no ] authentication { aka-v1 | md5 }
no

Disables the selected authentication type.

aka-v1 | md5

aka-v1: Specifies that the AKA-v1 algorithm will be used for subscribers using this access profile.

md5: Specifies that the MD5 algorithm will be used for subscribers using this access profile. This is the default setting for this command.


Usage:

Use this command to set the authentication method used for subscribers using this access profile.


Example:
The following command sets the authentication type for subscribers using this access profile to md5:
authentication md5
end

Exits the current configuration mode and returns to the Exec mode.

Product:

All


Privilege:

Security Administrator, Administrator


Syntax 
end

Usage:

Use this command to return to the Exec mode.

exit

Exits the current mode and returns to the parent configuration mode.

Product:

All


Privilege:

Security Administrator, Administrator


Syntax 
exit

Usage:

Use this command to return to the parent configuration mode.

sigcomp

Enables signalling compression for the Access Profile.

Platform:

ASR 5000

Product:

SCM (P-CSCF, A-BG)


Privilege:

Administrator


Syntax 
[ no ] sigcomp [ force ]
no

Disables signalling compression for the Access Profile.

force

Specifies that signaling compression is to be forced for the access type. When this feature is enabled, messages received by the P-CSCF/A-BG that are not compressed are rejected.


Usage:

Use this command to enable signalling compression for the specific Access Profile.

timeout

Sets timeout values for CSCF and SIP transactions for subscribers using this Access Profile.

Platform:

ASR 5000

Product:

SCM (P-CSCF, A-BG)


Privilege:

Administrator


Syntax 
timeout sip { 3gpp-d sec | 3gpp-t1 msec | 3gpp-t2 sec | 3gpp-t4 sec | d sec | invite-expiry sec | t1 msec | t2 sec | t4 sec }default timeout sip { 3gpp-d | 3gpp-t1 | 3gpp-t2 | 3gpp-t4 | d | invite-expiry | t1 | t2 | t4 }
sip { 3gpp-d sec | 3gpp-t1 msec | 3gpp-t2 sec | 3gpp-t4 sec | d sec | invite-expiry sec | t1 msec | t2 sec | t4 sec }

Sets transaction and expiry timers for SIP.

3gpp-d sec: This time is used to control the retransmission of 200OK messages to INVITEs after an ACK is sent. The ACK transaction is cleared after this period. This timer is applicable only for unreliable transport.

sec must be an integer from 0 to 2147483646.

Default: 64*T1 (128 seconds, recommended minimum)

3gpp-t1 msec: This timer is used to control the time interval between each retransmission. The interval doubles after each retransmission. This is used by P-CSCF/A-BG only when it sending message toward the UE. Example: T1, 2T1, 4T2, etc. This timer is applicable only for unreliable transport.

msec must be an integer from 0 to 2147483646.

Default: 2000 ms (2 secs, recommended minimum).

3gpp-t2 sec: This timer is used to control the period for which the request continues to get retransmitted. This is used by P-CSCF/A-BG only when it sending message toward the UE. This timer is applicable both for reliable and unreliable transport.

sec must be an integer from 0 to 2147483646.

Default: 16 seconds (recommended minimum).

3gpp-t4 sec: This timer is used to control the period for which the final response to non-invite transaction should be buffered. The buffered response for the retransmitted non-invite request should be sent within that interval. This timer is applicable only for unreliable transport.

sec must be an integer from 0 to 2147483646.

Default: 17 seconds (recommended minimum).

d sec: This time is used to control the retransmission of 200 OK to INVITE after ACK is sent. The ACK transaction will be cleared after this interval. This timer is applicable only for unreliable transport.

sec must be an integer from 0 to 2147483646.

Default: 64*T1 (32 seconds, recommended minimum)

invite-expiry sec: This timer is used by SIP while acting as UA Role and no final response is received for the INVITE request sent. This timer is applicable for both reliable and unreliable transport.

sec must be an integer from 0 to 2147483646.

Default: 100 seconds (recommended minimum).

t1 msec: Specifies the time interval (in milliseconds) between each retransmission. The interval doubles after each retransmission, for example: T1, 2T1, 4T2, etc. This timer is applicable only for unreliable transport.

msec must be an integer from 0 to 2147483646.

Default: 500 milliseconds (recommended minimum).

t2 sec: This timer is used to control the period for which the request keeps getting retransmitted. This timer is applicable both for reliable and unreliable transport.

sec must be an integer from 0 to 2147483646. The recommended minimum value for this parameter is 4 seconds.

Default: 64*T1 (32 seconds)

t4 sec: This timer is used to control the period for which the final response to non-invite transaction should be buffered so as to send the buffered response for the retransmitted non-invite request within that interval. This timer is applicable only for unreliable transport.

sec must be an integer from 0 to 2147483646.

Default: 5 seconds (recommended minimum).

default

Sets/restores default value assigned for specified parameter.


Usage:

Use this command to configure SIP Stack timers and CSCF service specific timers for subscriber traffic using this Access Profile.


Example:
The following command sets the SIP d timer to 64 seconds:
timeout sip d 64
