Overview
Profiles allow you to manage many interfaces easily and efficiently by configuring them dynamically. A profile contains a specific set of characteristics that can be assigned to multiple interfaces; you do not have to create identical interfaces separately.
The NMC-RX application enables you to assign IP, PPP, and Point to Point Protocol over Ethernet (PPPoE) parameters to a profile and associate the profile with an ATM subinterface or PPP interface on an E-series device.
Profiles can support a network running different versions of JUNOSe software. These dynamic interfaces are currently supported:
For additional information about dynamic interfaces for E-series routers, see JUNOSe Link Layer Configuration Guide, Chapter 13, Configuring Dynamic Interfaces.
Profiles with PPP Interfaces
For static PPP interfaces, you can assign a profile only for IP encapsulations. If a PPP interface has a profile associated with it, you cannot create an IP interface on top of that PPP interface.
Profiles with ATM Subinterfaces
For static ATM 1483 subinterfaces, you can assign one profile for each IP, PPP, and PPPoE encapsulation. You can also use the default Any for any autoconfigured encapsulation that does not have a specific profile assignment.
If a profile is specified for PPPoE or PPP, then the attributes of the lower layers (IP and possibly PPP) of that profile are used.
If a profile is assigned for any one of the encapsulation types on an ATM subinterface, nothing can be created on top of that ATM subinterface. If either the Auto Configure or Subscriber option is enabled, with the exception of an ATM circuit, you cannot create anything on top of that ATM subinterface. Also, if anything is already stacked on top of the ATM subinterface (such as an IP address), a profile cannot be associated with the subinterface, and the Auto Configure and Subscriber options cannot be enabled.
Devices with Different Versions
You can use profiles when your network is running devices with different versions of JUNOSe software. You can create a profile from both the Network Workshop and the Device Workshop; however, there are differences. Only the Device Workshop takes into account the JUNOSe software version.
