Using Profiles with Cisco 700 Series Routers
This section defines profiles and describes how to use profiles with the Cisco 700 series routers.
A profile is a set of configurations customized for and associated with a specific remote device. After being defined by the user, profiles are saved and stored in the Cisco 700 series router's nonvolatile random access memory (NVRAM), the memory used to store the router's configurations.
This appendix contains the following sections:
Instead of using one set of configurations to operate with all remote devices, you can customize your Cisco 700 series router to use individual configuration sets, or profiles, customized for each remote device.
This section provides an overview of profiles and includes the following sections:
Profile parameters are parameters that can be configured on a per-profile basis and, therefore, apply only to the connection with the remote router. After creating a new profile, these parameters can be reconfigured within that profile.
Any configuration changes to profile parameters while in profile mode apply only to that profile.
Table C-1 lists parameters that can be configured on a profile basis.
Table C-1 : Profile Parameters
| Profile Parameter | Profile Parameter |
|---|---|
| Line speed | PPP authentication (outgoing) |
| Auto calling | Loopback |
| Demand | Bridge filters (address, type, and user-defined) |
| Timeout | CPP passwords (client and host) |
| Called number | CHAP host secret |
| Encapsulation | PAP host password |
| Protocol | Callback |
| Learning | Callback ID security |
| Bridging | Callback receive numbers |
| Passthrough | All IP parameters, including filters |
| Compression | All IPX parameters, including filters |
| Subnet mask | Ringback number |
The Cisco 700 series routers are configured with three permanent profiles. Permanent profiles can be modified, but not deleted:
The system level is indicated by the system-level prompt, shown as follows:
Router_name>Use the set systemname command to configure the router name.
Note
The system level is composed of both system and profile parameters.
Changing any profile parameters at this level changes the values for the profile template. For more information about the profile template, refer to the section "Profile Template," later in this appendix.
System parameters are independent of profiles and affect the router as a system. System parameters can be changed only at the system-level prompt, shown as follows:
Router_name>Table C-2 lists the system parameters.
Table C-2 : System Parameter Set
| System Parameter | System Parameter |
|---|---|
| Caller ID parameters | PPP1 parameters |
| Date and time | Screen length |
| Directory number | Screen echo |
| Delay time | SNMP2 parameters |
| Forwarding mode | SPIDs3 |
| Multidestination dialing | Switch type |
| Numbering plan | System password |
| Patterns | Power Source 1 detect |
| Passthru | System name |
| Power Source 1 detect | Address age time |
| Call waiting | Country group |
| Local and remote access | CPP4 parameters |
| PPP client password | PPP client secret |
| Phone 1 and 2 | Voice priority |
The profile template consists of all the profile parameters as they are configured at the system level. All profiles are based on the profile template by inheriting these values. The profile template is modified by configuring profile parameters at the system level.
Any profile that has a specific profile parameter redefined within the profile is not affected by a change to the profile template configuration.
After you configure the profile template, you can customize individual profiles by entering profile mode for the profile and redefining the profile's parameters.
Profiles are either active or inactive. An active profile immediately creates a virtual connection to that profile's associated remote device. After creating a virtual connection, a demand call can be made to that profile's associated remote device.
Inactive profiles have no connection associated with them. No demand calls can be made with a profile that is configured as inactive.
Activity status is configured with the set profile command. To display these settings for an individual profile, use the show profile command while in profile mode for the profile.
At any time after the router is powered up, you can manually configure individual profiles to be inactive or active with the set active command.
This section describes how profiles are related to connections.
A connection is a dynamically created pipeline of packets to a remote site.
Connections are closely related to profiles because all connections are associated with a profile that defines the configuration of the connection.
A virtual connection is a connection without any existing physical channels. A physical connection is a connection with one or more existing physical channels. Profiles can be set to be either active or inactive. After a profile is created, setting it to active creates a virtual connection to the associated remote device. After a call is made to the associated remote device, the connection becomes an physical connection.
Virtual and physical connections behave similarly; the only difference is that physical connections are forwarding packets. Virtual connections exist in order to monitor packet traffic until a demand filter causes a call to be initiated. After this happens, the virtual connection becomes an active connection.
If the remote user makes a call to you, the remote device is identified and associated with the virtual connection created by the user's profile. When the router accepts the call, a virtual connection becomes a physical connection, even if the profile was configured to inactive with the set inactive command.
This section describes how to create new profiles and contains the following sections:
Create a new profile with the set user command. New profiles by default inherit all of the profile template values.
After creating a new profile, you automatically enter profile mode for that profile. Profile mode is indicated by the system prompt, which appear as the system name followed by the profile name, as follows:
Home:JohnS>Configuring Profile IDs
After creating the profile, you should configure the profile with the Media Access Control (MAC)-layer address of the remote device that is associated with the profile. Use the set profile id command to do this.
If an incoming call is received from a remote device using its MAC-layer address as its user ID, your router uses that MAC-layer address to locate the associated user profile. The correct profile should have the matching MAC-layer address entered as its user address. After it is located, all of the profile's parameters are used during the call process.
An outgoing call made with a profile does not require that a user address be entered into the profile.
Use the set active command to configure a profile to be either active or inactive.
The change user command is used to move between profiles as well as to return to the system level when in profile mode.
To enter the profile mode for any existing profile, enter the change user command with the profile's name, as follows:
cd profile name
To return to the system level from profile mode, enter the change user command without a profile name, as follows:
cd
Modifying User Profiles
This section describes how to modify existing user profiles and contains the following sections:
Remove any parameter value that you set locally within a profile with the unset command, as follows:
For a complete list of values that can be deleted with the unset command, refer to the Cisco 750 Series and Cisco 760 Series Command Reference publication.
Use the reset user command to delete any user profiles from the router.
The three permanent profiles (described in the section "Permanent Profiles," earlier in this appendix) cannot be deleted.
This command also closes any connection associated with the profile.
Use the set profile user command to change the name of an existing profile. Use this command while in profile mode for the profile that you want to affect. In the following example, the profile name is being changed from SanJose to NorthSanJose:
You can use any of the show commands while in profile mode, just as you do at the system level.
In profile mode, some show commands only display profile parameters. Parameter values that have been redefined at the profile level are indicated with a <*>. All other parameter values are inherited from the profile template.
This section describes how profiles affect ISDN calling and contains the following sections:
When the router receives an incoming call, the calling unit provides its MAC-layer address. The router it searches both active and inactive profiles that have the same MAC-layer address configured with the set user id command. If it finds an active or inactive profile with the matching user ID, the router uses the configuration parameters of that profile while communicating with the remote router. It does not matter if the matching profile is active or inactive at the time of the call; the call process proceeds in the same way.
After the call is finished, the physical link between the two devices is disconnected. However, the virtual connection to the remote router might still exist, depending on how the profile has been configured with the command set profile: either keep active on disconnection or deactivate on disconnection.
If the profile is configured to keep active after a link disconnects, a virtual connection remains with the remote device. If the profile is configured to become inactive after a link disconnects, both the physical link and the virtual connection to the remote router are disconnected until another call is received from the same remote router.
If there are no active or inactive profiles that have a user ID that matches the remote router's MAC-layer address, the profile Standard becomes active for the duration of the call. The Standard profile is a profile used for calls from devices with no associated profile. The following section describes how to configure the standard profile to prevent calls from unknown callers from being connected.
The Standard profile is one of the three default profiles configured in the router.
The Standard profile cannot be deleted, but can be modified just like any other profile. The Standard profile's default configuration is activated on power up and remains active after call disconnection.
The Standard profile can be used to prevent unknown calls from being connected to the router. The simplest way to do this is to configure the profile with a random value for the following parameters:
Outgoing calls are affected by the activity status (active or inactive) of user profiles.
To make an on-demand call to a remote router using the remote router's associated profile, the profile must be active. No demand calls are made to a remote device with an inactive profile.

Host> cd Profile
Use the unset command to remove the profile-based parameter from the profile:
Host:Profile> unset number
After you issue this command, the parameter that you removed inherits its value from the router's profile template.
