Nested Profile Assignments

The configuration for each dynamic upper-interface encapsulation type might differ, depending on the column type built by the router. To manage these differences, you can include one or more nested profile assignments within the ATM 1483 base profile. A nested profile assignment references another profile that configures attributes for a dynamic upper-interface encapsulation type. You can create different profiles for each upper-interface encapsulation type, or you can create a single profile that includes attributes for multiple encapsulation types.

For example, the following commands create a base profile named atm1483BaseProfile with two nested profile assignments. The first nested profile assignment references an IP profile named atm1483ProfileIp, and the second nested profile assignment references a PPP profile named atm1483ProfilePpp.



host1(config)#profile atm1483BaseProfile 

host1(config-profile)#atm atm1483 profile
ip atm1483ProfileIp 

host1(config-profile)#atm atm1483 profile
ppp atm1483ProfilePpp

In this example, atm1483ProfileIp and atm1483ProfilePpp have different IP configurations depending on the dynamic interface column constructed. For an IP over ATM (IPoA) dynamic interface column, the router uses the IP attributes in atm1483ProfileIp. For an IP over PPP over ATM dynamic interface column, the router uses the IP attributes in atm1483ProfilePpp.

The concepts that apply to profiles created for upper-interface encapsulation types configured over static ATM 1483 subinterfaces also apply to profiles created for upper-interface encapsulation configured over dynamic ATM 1483 subinterfaces. For information about creating profiles for upper-interface encapsulation types, see Configuring Dynamic Interfaces.
