Spacevars
0product
throttles the sending or policy requests to either active or standby policy server. Options are:

  • enabled
  • disabled (default)
 ipInterfaceGroup  

The IP Interface Group belonging to the configured address context. This IP Interface Group is used for communicating with the external PSX.

Note

This parameter is only configurable once addressContext is set.

mgmtInterfaceGroup

Specifies the Management Interface Group to be used for communication with an external PSX.

Note

If attribute type is set to "ip", this parameter is no longer configurable.

reconnectTimeout

1-3600

Specifies the timeout period in seconds to re-attempt the connection to a policy server that is in the enabled state. Default is 10 seconds.

switchOverMode

N/A

Specifies the mode to switch over the policy server to active state. Mode can be:

  • automatic (default) – in this state the policy server automatically retries to the previously ACTIVE policy server after a switch-over.
  • manual – In this state you have to manually set the policy server to ACTIVE state after a switch-over.
typeN/A

Parameter

Length/Range

Description

localServer

N/A

Specifies the name of the local policy server.

action

N/A

Specifies the method on which queued transactions are processed, when operational state is either standby or out-of-service:
dryup (default) all queue entries are processed to completion unless retries expires.
force — all queue transactions are dropped immediately.

keepAliveTimer

1-60

Specifies the time interval (in seconds) to wait before issuing a "keepalive" poll to the policy server. This poll is issued only if there is no other policy server activity during this interval. The receipt of any message from the policy server resets the elapsed time to 0.
Must be 1-60, default is 5.

mode

N/A

Specifies the operational state of the local policy server:

  • outofservice – The local policy server is out-of-service and will not provide any services.
  • active – The local policy server provides normal query services.
  • standby – The local policy server serves as a backup when another server in the active mode becomes unavailable.
  • alternate – The local policy server is not expected to receive any query messages, but can send messages to SBC. 

    Note
    If two external active policy servers fail and local policy server is in standby mode, the standby local policy server is used as active server until the external policy server becomes active.

retries

0-32

Specifies the number of retries for any policy server transaction. Must be 0-32, default is 1.

retryTimer

N/A

Specifies the time (in milliseconds) for the

Spacevars
0product
to wait for the response from the local policy server. (default = 2500).

state

N/A

Note
If changing the state, ensure mode is set to "outofservice".


The administrative state of the local policy server.

Options are:

  • disabled – The local policy server is not used for call routing decisions.
  • enabled – The local policy server is used for call routing decisions.

transactionTimer

50-60000

Time to wait (in milliseconds) for a reply from the initial transaction request. When this timer expires, a transaction retry will be issued. Subsequent retries of this transaction are controlled by retries. Must be 50-60000, default is 2500.

displaylevel

1-64

Displays the different levels of output information in show commands.
