.
`mgmtInterfaceGroup`	N/A	Specifies the Management Interface Group to be used for communication with an external PSX.

Command Parameters

Caption

0	Table
1	Command parameters

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

0	product

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

...

state

...

N/A

.
`state`	N/A

...

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.

NOTE: If changing the state, ensure mode is first set to "outofservice".

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.
