Internal objects created for L2TP and NAT

Some services such as L2TP LNS (L2TP Network Server) and NAT (Network Address Translation) automatically create service objects for internal use. In particular, an IES service with ID 2147483648 is created. In that service, or in configured VPRN services, service objects such as interfaces, SAPs and related objects can be automatically created for internal use.

Named objects reserved for internal use have a name that starts with ‟_tmnx_”. Objects with a numeric identifier created for internal use have an identifier from a reserved range.

The general rules for objects reserved for internal use:

appear in CLI show commands and MIB walks output.
appear in the output of info detail commands but are never in the output of admin save [detail].

It may be possible to enter the CLI node of such an object, but it is not possible to change anything. It may also be possible to set the value of one of its objects to the current value with SNMP, but it is never possible to change any value.
