# CSCF Peer Server Monitoring Configuration Mode Commands

The CSCF Peer Server Monitoring Configuration Mode is used to configure an individual peer server’s monitoring parameters and operational mode. It also associates a network session template with the server.

IMPORTANT:

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

Exits the current mode and returns to the Exec Mode.
Product:

All
Privilege:

Administrator
Syntax

    end

Usage:

Change the mode back to the Exec mode.
exit

Exits the current mode and returns to the previous mode.
Product:

All
Privilege:

Administrator
Syntax

    exit

Usage:

Return to the previous mode.
ims-capable

Indicates whether the peer server belongs to a 3GPP/IMS network or a non-IMS network such as the Internet. This command is used to determine at the S-CSCF whether SIP signaling inter-working is needed when the calls are forwarded to external networks.
Platform:

ASR 5000
Product:

SCM (S-CSCF)
Privilege:

Administrator
Syntax

    [ no ] ims-capable

no

Removes the identification of “IMS capable” from the selected peer server.
Usage:

Use this command to identify a peer server as IMS capable allowing the S-CSCF to use SIP signalling inter-working when forwarding calls to non-IMS capable networks.
lro-selection-profile

Binds a CSCF last route profile with the peer server.
Platform:

ASR 5000
Product:

SCM
Privilege:

Administrator
Syntax

    lro-selection-profile
    name profile_nameno lro-selection-profile

lro-selection-profile name profile_name

profile_name must be an existing CSCF last route profile and be from 1 to 79 alpha and/or numeric characters.
no lro-selection-profile

Removes CSCF last route profile from the peer server group.
Usage:

Use this command to identify a CSCF last route profile to use for finding the correct Public Safety Answering Point (PSAP) during emergency calls.
Example:
The following command assigns a CSCF last route profile named lro1 to the peer server group:

    lro-selection-profile
    name lro1

The following command removes a CSCF last route profile from the peer server group:

    no lro-selection-profile

mode

Sets the peer server mode to either active or standby. By default, peer servers are in active mode.
Platform:

ASR 5000
Product:

SCM
Privilege:

Administrator
Syntax

    mode { active | standby }

active

Defines the mode of the CSCF peer server as active.
standby

Defines the mode of the CSCF peer server as standby.
Usage:

Use this command to set the peer server mode to either active or standby.
Example:
The following command sets the peer server’s mode to standby:

    mode standby

monitor-status

Sets parameters for monitoring the status of peer servers.
Platform:

ASR 5000
Product:

SCM
Privilege:

Administrator
Syntax

    monitor-status { max-response-codes
    negative max | [ monitor-interval seconds ] [ monitor-message
    options [ max-forwards max | response-timer seconds ] ]  [ monitor-response-timer seconds ] | response-code { positive SIP_response_code | negative SIP_response_code } | timer [ mark-out-of-service seconds ] [ unavailable-monitor-interval seconds ] [ unavailable-notification seconds ] }no monitor-status { monitor | response-code [ negative | positive ]  [ SIP_response_code ] }

Default: 1

Specifies the maximum number of negative response codes to receive to mark server unavailable.

max must be an integer from 1 to 10.
monitor-interval seconds

Default: 30

Specifies the interval that peer server monitoring will occur.

seconds must be an integer from 1 to 65535.
monitor-message options [ max-forwards max | response-timer seconds ]

Specifies that SIP message (OPTIONS) are to be sent periodically after each monitoring interval.

max-forwards max: Max-forwards in number of hops. max must be an integer from 0 to 70.

response-timer seconds: Response wait timer in seconds. seconds must be an integer from 1 to 65535.
monitor-response-timer seconds

Default: 180

Specifies the interval that the CSCF will wait for responses from the peer server.

seconds must be an integer from 1 to 65535.
response-code { positive SIP_response_code | negative SIP_response_code }

Specifies the Options Message response codes.

negative: Negative response codes. SIP_response_code must be an integer from 300 to 699.

positive: Positive response codes. SIP_response_code must be an integer from 200 to 299.
timer mark-out-of-service seconds

Default: 864000

Timer to mark server out-of-service from unavailable state.

seconds must be an integer from 0 to 2147483646.
