Profile Characteristics

560
In contrast to static PPP interfaces (above which only dynamic IP interfaces can be
created), static ATM 1483 subinterfaces support recognition and creation of the following
upper dynamic interface types or encapsulations: bridged Ethernet, IP, IPv6, Multilink
PPP, PPP, and PPPoE interfaces. The auto-configure command identifies the
encapsulation type. For flexibility, the router provides the ability to configure an ATM
1483 subinterface with distinct profile assignments for each encapsulation type supported
by the auto-configure command.
In contrast to dynamic ATM 1483 subinterfaces, dynamic VLAN subinterfaces support
recognition and creation of simultaneous IP and PPPoE upper dynamic interface types.
The vlan auto-configure command identifies the encapsulation type. For flexibility, the
router provides the ability to configure a VLAN subinterface with distinct profile
assignments for each encapsulation type supported by the vlan auto-configure command.
Each profile typically contains configuration attributes for the expected encapsulation,
in addition to attributes for other higher-interface layers through IP. If your configuration
of upper layers is intended to be different depending on which incoming encapsulation
is received by the subinterface, configure and assign separate profiles for each
encapsulation type. If your configuration of upper layers is the same for more than one
encapsulation type, configure one profile and assign it for those encapsulation types.
Currently, profiles support bridged Ethernet, IP, IPv6, L2TP, Multilink PPP, PPP, PPPoE,
and VLANs. You create a profile with a specific set of characteristics. You then assign
the profile to multiple interfaces instead of creating separate interfaces with identical
attributes. After you create a profile, you can assign it to static ATM 1483, static PPP, or
static VLAN major interfaces on different devices.

Bridged Ethernet Characteristics

A profile can contain the following bridged Ethernet characteristic:
mtu—Sets the maximum allowable size, in bytes, of the maximum transmission unit
(MTU) for dynamic bridged Ethernet interfaces

IP Characteristics

A profile can contain one or more of the following IP characteristics:
access-routes—Enables the creation of host access routes on an interface
address—Configures an IP address on an interface
auto-configure ip-subscriber—Configures a primary IP interface to enable dynamic
creation of subscriber interfaces
auto-detect ip-subscriber—Enables packet detection on the router and specifies that
IP automatically detects packets that do not match any entries in the demultiplexer
table
directed-broadcast—Enables directed broadcast forwarding
filter-options all—Filters out packets that include IP options
