The Path Check Profile specifies the conditions that constitute a connectivity failure, and in the event of such a failure, the conditions that constitute a connectivity recovery. This section describes the CLI syntax, parameter descriptions and command examples.
Refer to Path Check Support for additional feature details.

After updating a Path Check Profile, you must disable and re-enable the profile for the change to take effect. |

Parameter | Length/Range | Description |
|---|
pathCheckProfile
| 1-23 | <profile name> – The name of the Path Check Profile.
| failureResponseCodes
| 400-699, or
(all, all4xx, all5xx, all6xx) | Use this parameter to define one or more response codes to treat as failure responses. The options include the following: 400-699 – Enter a single code, or enter multiple codes within square brackets and separating each entry with a space. For example, [409 505 699]all – include all response codes from 400-699all4xx – include all 4xx response codesall5xx – include all 5xx response codesall6xx – include all 6xx response codes
INFO: When you use more than one value, enclose the values in square brackets [ ], separating each value with a space. Entering a value without using brackets appends the value to the existing configuration.
NOTE: Ensure failureResponseCodes values for Path Check Profile and SIP ARS Profile within the same zone/trunk group use similar values to avoid unexpected behavior. For example, it is not advisable to set Path Check Profile failureResponseCode to "all" and SIP ARS Profile failureResponseCodes to "all4xx" and "all6xx". Refer to SIP ARS Profile - CLI. | protocol
| N/A | The ping protocol type used. icmp – Internet Control Message Protocol (ICMP)sipOptions (default)
NOTE: Create a user ACL for ICMP if there are more than 50 sessions to support. NOTE: Configure static routes to reach the target IP from interface through which the ICMP pings are generated. | recoveryCount
| 1-10 | The number of consecutive successful responses to occur before removing the endpoints from the Blacklist. (default = 6) | replyTimeout | 1-300 | The time interval (in seconds) to elapse after which the ICMP PING request times out. (default = 1) NOTE: This parameter applies when protocol = icmp. | replyTimeoutCount
| 1-10 | The number of consecutive timeouts to occur before adding the endpoints to the Blacklist. (default = 6) | sendInterval
| 1-600 | Specifies interval (in seconds) in which the PING request will be sent out to the endpoints. (default = 60) | transportPreference | N/A | Transport preference for sending OPTIONS method.
Note: A good practice is to configure separate pathCheckProfiles for each transport type; each profile having only preference1 set. By assigning a pathcheck profile with a transport type matching an ipPeer's transport type, you will ensure that SBC will not send SIP OPTIONS ping over a protocol that a particular ipPeer does not support. Possible completions:
Defaults by preference: preference1 – Default value is sip-udppreference2 – Default value is sip-tcppreference3 – Default value is tls-tcppreference4 – Default value is sctp
Note: Ensure that the SIP Sig Port transportProtocolsAllowed setting is configured to support the chosen transport preference (see zone sipSigPort refer to Zone - SIP Sig Port - CLI page). |

Command Examples
This example creates a patch check profile named "PCP-1" with the default ping protocol type "sipOptions", a recovery count of "7" and a send interval of "120" seconds. The reply timeout count is left at the default of "6". Next, the PCP is assigned to "defaultSigZone" zone for default address context using IP address "10.20.120.21".
| Code Block |
|---|
|
% set profiles services pathCheckProfile PCP-1 protocol
sipOptions recoveryCount 7 sendInterval 120
% show profiles services pathCheckProfile PCP-1
protocol sipOptions;
sendInterval 120;

% set addressContext default zone defaultSigZone ipPeer

% show addressContext default zone defaultSigZone ipPeer

To configure a single failureResponseCodes value for a Path Check Profile:
| Code Block |
|---|
|
% set profiles services pathCheckProfile PCP_1 failureResponseCodes 404 |
To set multiple failureResponseCodes values:
| Code Block |
|---|
|
% set profiles services pathCheckProfile PCP_1 failureResponseCodes [ 404 503 all6xx ] |
To delete a single failureResponseCodes value:
| Code Block |
|---|
|
% delete profiles services pathCheckProfile PCP_1 failureResponseCodes all6xx |
To delete all failureResponseCodes values:
| Code Block |
|---|
|
% delete profiles services pathCheckProfile <pathCheckProfile_name> failureResponseCodes [] |
