Glossary

T

TACACS

Telnet

Terminal Access Controller Access Control System, a an authentication server that validates user IDs and passwords, thus controlling entry into systems.

A service that lets you log in to a system over a network just as though you were logging in from a remote character terminal attached to the system. It is commonly used to provide an Internet service that is exactly the same as the one you would get if you dialed into the system directly with a modem.

Trap

A network message of a specific format issued by an SNMP entity on behalf of a network management

 

agent application. A trap is used to provide the management station with an asynchronous notification

 

of an event.

Tunnel

A tunnel is defined by an LNS-LAC pair. The tunnel carries PPP datagrams between the LAC and the

 

LNS; many sessions can be multiplexed over a single tunnel. A control connection operating in band

 

over the same tunnel controls the establishment, release, and maintenance of sessions and of the tunnel

 

itself.

Tunnel Network

A server that terminates a tunnel. In PPTP terminology, this is known as the PPTP Network Server

Server

(PNS). In L2TP terminology, this is known as the L2TP Network Server (LNS).

U

UDP

User List

User Record

Users

User Datagram Protocol, a data packet protocol.

The list of users registered for dial-in access.

The UserRecord contains all the information that needs to be accessed at runtime about a particular user. This enables it to be read in one database operation in order to minimize the cost of authenticating the user. The UserRecord is stored as an encrypted string in the MCD database, because it contains the user’s password, amongst other things.

Users are represented by entities in specific UserLists. See User Record.

V

Vendor

VHG

Each NAS has a vendor associated with it. A vendor may specify attributes for the NAS that are not part of the standard specification.

Virtual Home Gateway—a Cisco IOS component that terminates PPP sessions. It is owned and managed by the service provider on behalf of its customer to provide access to remote users of that customer’s network. a single service provider device (router) may host multiple VHGs of different customers. a VHG may be dynamically brought up and down based on the access pattern of the remote users. Note that there is no single IOS feature called the VHG; it is a collection of function and features (PPP, virtual profiles, VRFs, etc.).
