- Example
  `
  host1(config-service-profile)#include hostname
  `
- Use the no version to disable inclusion of the router hostname in the username.
- See include hostname

include ip-address

- See include virtual-router-name

ip auto-configure ip-subscriber

- Use to configure an IP interface to support creation of dynamic subscriber interfaces. The specified IP interface is considered the primary interface.
- The router creates the required dynamic subscriber interfaces when the IP address is assigned to the associated subscriber. The address might be assigned by an external DHCP server, the DHCP local server, or the packet detect feature.
- Use the include-primary keyword to specify that the primary interface can be assigned to a subscriber. Use the exclude-primary keyword to specify that the primary interface cannot be used for subscribers. The primary interface is not assigned to a subscriber by default.
- You can issue this command from Interface Configuration mode, Subinterface Configuration mode, or Profile Configuration mode.
- Example
  `
  host1(config-if)#ip auto-configure ip-subscriber include-primary
  `
- Use the no version to disable creation of dynamic subscriber interfaces associated with this primary IP interface. Use the no version with the include-primary keyword to specify that the primary interface is not assigned to a subscriber. Use the no version with the exclude-primary keyword to specify that the primary interface is assigned to a subscriber.
- See ip auto-configure ip-subscriber

ip auto-detect ip-subscriber

- Use to set the router packet detect feature and specify that IP automatically detect packets that do not match any entries in the demultiplexer table. When an unmatched packet is detected, an event is generated that determines whether to create a dynamic subscriber interface or configure an existing interface.
- You can issue this command from Interface Configuration mode or Profile Configuration mode.
- Example
  `
  host1(config-if)#ip auto-detect ip-subscriber
  `
- Use the no version to restore the default, in which packet detection is disabled.
- See ip auto-detect ip-subscriber

ip destination-prefix

- Use to specify a destination address for a subscriber interface or for a primary IP interface.
- Use the deny keyword to drop all packets that match the command.
- On the ERX-1440 router or the E320 router, you can configure up to 1024 subnets for static subscriber interfaces per primary IP interface when each subnet has a variable network mask that is less than /32. The number of subnets identifying a single route (/32) is still limited by the global maximum of 16,000 hosts per line module.
- Example
  `
  host1(config-if)#ip destination-prefix 10.0.0.0 255.0.0.0
  `
- Use the no version to remove the association between the interface and the specified IP destination address and mask.
- See ip destination-prefix

ip inactivity-timer

- Use to configure the inactivity timer value for an IP interface.
- A dynamically created subscriber interface is deleted if it is inactive for a period longer than the inactivity timer value. IP polls the dynamic interface at the configured interval to determine whether the interface was active during the interval. Inactive interfaces are deleted only when the period of inactivity is equal to or greater than the configured value.

  For example, if you configure an inactivity timer of 15 minutes, IP polls the interface every 15 minutes. If a poll determines that the interface was last active 14 minutes earlier, the inactive time is less than the configured value so nothing happens. IP polls again 15 minutes later. If the interface is still inactive then the total period of inactivity is now 29 minutes. This is greater than the configured value and the interface is deleted.

- On static interfaces, the subscriber’s access route is removed when the inactivity timer is exceeded. When the subscriber logs back in, the timer is restarted.
- The timer value can in the range 0–65335 minutes. A timer value of 0 specifies that dynamically created subscriber interfaces are never deleted by the inactivity timer.
- Example
  `
  host1(config-if)#ip inactivity-timer 100
  `
- Use the no version to restore the default, in which inactivity timer feature is disabled.
- See ip inactivity-timer

ip re-authenticate-auto-detect ip-subscriber

- Use to re-authenticate the auto-detected subscribers or Dynamic Subscriber Interfaces (DSIs) created on static and dynamic primary IP interfaces, using the DHCP options when the DHCP external application manages the DSIs following a cold boot. The no version negates the command or restores the defaults.
- You can issue this command from Interface Configuration mode or Profile Configuration mode.
- Example
  `
  host1(config-if)#ip re-authenticate-auto-detect ip-subscriber
  `
- Use the no version negate the command or restore the defaults.

ip route-map ip-subscriber

- Use to configure an interface to perform route-map processing, and to specify the route map that is applied to the IP interface subscriber. If no route map is specified, then all packets trigger the creation of a dynamic subscriber interface.
- You can issue this command from Interface Configuration mode or Profile Configuration mode.
- Example
  `
  host1(config-if)#ip route-map ip-subscriber bostonRouteMap
  `
- Use the no version to delete the route map.
- See ip route-map ip-subscriber

ip service-profile

- Use to specify a service profile name and to enter IP Service Profile Configuration mode. Service profiles contain user and password information, and are used in route maps for subscriber management and to authenticate subscribers with RADIUS.
- You can specify a service profile name with up to 32 ASCII characters.
- To use the subscriber management application to configure IP subscribers on dynamic bridged Ethernet interfaces to support RADIUS authentication, you can create an IP service profile and assign it to a dynamic bridged Ethernet interface profile. If your router is running stateful SRP switchover (high availability), using an IP service profile to configure subscriber authentication is preferable to using either the subscriber command or the atm atm1483 subscriber command because these commands can suspend stateful SRP switchover on the router or prevent it from becoming active.

  For more information, see the Authenticating Subscribers on Dynamic Bridged Ethernet over Static ATM Interfaces section or the Authenticating Subscribers on Dynamic Bridged Ethernet over Dynamic ATM Interfaces section in JUNOSe Link Layer Configuration Guide.

- Example
  `
  host1(config)#ip service-profile class1Service
  host1(config-service-profile)#
  `
- Use the no version to delete the service profile.
- See ip service-profile

ip source-prefix

- Use to specify a source address for a subscriber interface.
- Use the deny keyword to drop all packets that match the command.
- On the ERX-1440 router or the E320 router, you can configure up to 1024 subnets for static subscriber interfaces per primary IP interface when each subnet has a variable network mask that is less than /32. The number of subnets identifying a single route (/32) is still limited by the global maximum of 16,000 hosts per line module.
- Example
  `
  host1(config-if)#ip source-prefix 10.0.0.0 255.0.0.0
  `
- Use the no version to remove the association between the interface and the specified IP source address and mask.
- See ip source-prefix

ip use-framed-routes ip-subscriber

- Use to configure a static primary IP interface to use framed routes as source IP addresses when creating dynamic subscriber interfaces. The router uses the Framed-Route RADIUS attribute [22] sent in Access-Accept messages to apply framed routes to subscriber interfaces associated with the primary interface.
- Example
  `
  host1(config-if)#ip use-framed-routes ip-subscriber
  `
- Use the no version to disable the use of framed routes when creating dynamic subscriber interfaces associated with this primary IP interface.
- See ip use-framed-routes ip-subscriber

- You can specify a password with up to 32 ASCII characters.
- Example
  `
  host1(config-service-profile)#password mypassword
  `
- Use the no version to remove the password from the IP service profile.
- See password

set ip interface-profile

- Use to specify a dynamic subscriber interface profile that is used in the route map.
- Example
  `
  host1(config)#route-map mapForEPort

- Example
  `
  host1(config-route-map)#set ip source-prefix 10.10.30.0 255.255.255.0 primary
  `
- Use the no version to remove the source address range from the route map.
- See set ip source-prefix

user-name
