SIP Interface Constraints Monitoring

The session constraints configuration allows you to set up a body of constraints that you can then apply them to a SIP interface. Using the constraints you have set up, the Oracle Communications Session Border Controller checks and limits traffic according to those settings for the SIP interface.

SIP interfaces have two states: “In Service” and “Constraints Exceeded.” When any one of the constraints is exceeded, the status of the SIP interface changes to Constraints Exceeded and remains in that state until the time-to-resume period ends. The session constraint timers that apply to the SIP interface are the time-to-resume, burst window, and sustain window.

You can view information about constraints for a SIP interface by using the show sipd interface command. Using that command, you can show statistics for all SIP interfaces, or for one that you specify when you carry out the command.

All SIP Interfaces

To display statistical information for all SIP interfaces:

  1. Type show sipd interface at the command line and then press Enter. The results will resemble the following example. 
    ORACLE# show sipd interface
19:38:17-18
          ---- Inbound ---- --- Outbound ---- -Latency-  --- Max ---
Realm     Active Rate ConEx Active Rate ConEx  Avg  Max Burst In Out
external       0 0.0      0      0  0.0     0  0.0  0.0     0  0   0

Single SIP Interface

To display statistical information for a single SIP interfaces:

  1. Type show sipd interface at the command line, followed by the realm identifier for that interface, and then press Enter. The results will resemble the following example.
    ORACLE# show sipd interface internal
19:46:10-37
