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. Refer to Path Check Support for details.

Note

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


Note

From 6.2.0 release onward, the SBC determines the SRS reachability only through the SIP ARS status. The pathCheckProfile must be configured to determine the reachability of the SRS peers and treat failure response such as 501 as OPTIONS failure.

To View Path Check Profile

On the SBC main screen, go to Configuration > Profile Management > Category: Service Profiles > Path Check Profile.

The Path Check Profile window is displayed.

For more information on the parameters and their values, see Path Check Profile - Parameter Description Table.

Parameter

Description

Name

Specifies the name of the Path Check Profile. This is a mandatory field.

Failure Response Codes

Use this parameter to define one or more response codes to treat as failure responses. The options include one or more of the following values, separating each entry with a space:
 400-699 - list codes individually

  • all – include all response codes from 400-699
  • all4xx – include all 4xx response codes
  • all5xx – include all 5xx response codes
  • all6xx – include all 6xx response codes
Note

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 configurations.

The Failure Response Codes values for Path Check Profile and Sip Ars Profile within the same zone/TG has similiar values to avoid unexpected behavior. For example, it is not advised to set Path Check Profile Failure Response Code to "all" and Sip Ars Profile Failure Response Codes to "all4xx,all6xx".

Note

In the EMA, the Failure Response Codes are configured as comma separated values. In CLI, the values of the Failure Response Code are separated by space.

Protocol

Specifies the ping protocol type used.

  • SIP Options (default)
  • Icmp

Send Interval

This is a mandatory field.

Reply Timeout

Specifies the time interval in seconds for the ping request to timeout.

Note: This parameter is displayed only if the parameter Protocol is set to Icmp.

Reply Timeout

Specifies the number of consecutive error responses that should occur before adding the endpoints to the Blacklist. Enter value in range of 1-10. The default value is 6.
This is a mandatory field.
