Cisco Systems 700 Permanent Profiles, Lists the parameters that can be configured in a profile

System and Profile Parameters

Table 2-2 lists the parameters that can be configured in a profile.

Bridging	Line speed	PPP authentication (outgoing)
Ringback number	Auto calling	All IP parameters, including filters
Passthrough	Demand	PAP password (client and host)
Learning	Timeout	All IPX parameters, including filters
Subnet mask	Called number	CHAP secret (client and host)
Protocol	Encapsulation	Bridge filters (address, type, and user-defined)
Loopback

Permanent Profiles

Cisco 700 series routers contain three permanent profiles. Permanent profiles can be modified, but they cannot be deleted. The permanent profiles are as follows:

LAN	Determines how data is passed from the router to the LAN. This profile
	is commonly used for connections made directly to the local network.
Internal	Determines how data is passed between the bridge engine and the IP/IPX
	router.
Standard	The default profile. If authentication is set to none and a profile does not
	exist for the WAN switch, the router uses the Standard profile by default.
	If authentication is required and no profile is found, the call is dropped.

The decision to use the LAN or Internal profile involves some knowledge of your network design and whether you are bridging or routing to remote sites (or a combination of both). It is best to use the LAN profile instead of the Internal profile to simplify the configuration. You can easily associate the LAN profile with the Ethernet interface and the user-defined profiles with the ISDN interface.

Sometimes situations arise (very infrequent) where you must route a protocol to one site and bridge the same protocol to another site. Simply leave the LAN profile as a bridging profile, and use the Internal profile for all routed protocol information.
