Setting Up the Caller Resolution Table
For network security, all three dial services use a PPP identification mechanism to
determine who is calling the router. PPP performs this identification process using
one of two authentication protocols, CHAP or PAP. CHAP is the default protocol.
To identify an incoming remote caller, you enter the name and CHAP secret of
each remote caller in a caller resolution table, and associate each name with a
local demand, primary, or bandwidth circuit. When a router receives an incoming
call, it checks the caller resolution table for an entry that identifies the caller. If the
caller is authorized, the local router activates a circuit.
To configure the caller resolution table:
1. Begin at the Configuration Manager window (refer to Figure 1-1).
2. Select Dialup > Caller Resolution Table.
Site Manager displays the Caller Resolution Table window (Figure
1-33).
