Figure 70. Priority service diagram

By default, the service drops any lower priority calls if a higher priority call fails. However, you have the option to limit the number of lower priority calls to be dropped if a higher priority call fails. It also blocks new lower priority calls for a configurable time after a higher priority call failed.

The following procedure demonstrates how to configure a priority service.

Mode: context cs

Step	Command	Purpose
1	node(ctx-cs)[ctx-name]# service	Create a priority service.
	priority <svc-name>
2	node(svc-prio)[svc-name]# port	Create a port within the service.
	<port-name>
3	node(port)[port-name]# route	Define the routing destination for calls received on this
	dest-….	port.
4	node(port)[port-name]# service	Define the priority for calls received through this port.
(Optional)	priority	(The default priority level is 0)
5	node(port)[port-name]# exit	Leave the port configuration mode
6		Repeat steps 2 to 5 for any additional calls you need to
		create.
7	node(svc-prio)[svc-name]# max-	Define the maximum number of lower priority calls to be
(Optional)	calls-to-drop <calls>	droppedif a higher priority call fails. (Default is to drop
		any lower priority calls.)
8	node(svc-prio)[svc-name]#	Define the time for which lower priority calls are
(Optional)	quiesce-time <seconds>	blocked after a higher priority call failed. (Default is
		15 seconds.)
9	node(svc-prio)[svc-name]# retry-	Define the time for which the service waits after a
(Optional)	timeout <seconds>	higher priority call failed until it tries to establish it for a
		second time. This allows resources used by dropped
		lower priority calls to get available again. (Default is
		3 seconds.)

Note Although this service improves the probability that higher priority calls can be established successfully, there is no guarantee that a higher priority task can be established successfully at any time.
