Table2. Network Architecture and the Supported Interfaces (continued)
Network Architecture Supported Interfaces
Dial-In APPP dial circuit interface that has configuration parameters
defaulted to support DIALs
Multilink PPP (MP) Supported on any PPP link
L2TP Supports virtual PPP DIALs connections through the Layer 2
Tunneling Protocol (L2TP).
Notes:
1. PPP dial circuit interfaces can use ISDN, a V.34 network, or V.25bis as the base
network interface.
2. FR dial circuit interfaces can use an ISDN or a V.25bis network as the base
network interface.
3. Dial-Out circuit interfaces use a V.34 network as the base network interface.
4. Dial-In circuit interfaces can use an ISDN or V.34 network as the base network
interface.
5. SDLC dial circuits use V.25bis as the base network interface.
6. X.25 uses the ISDN BRI D-channel as the base network interface.
Accessing the Network Interface Console Process
Tomonitor information related to a specific interface, access the interface console
process by using the following procedure:
1. At the OPCON prompt, enter the OPCON talk command and the PID for
GWCON. For example:
*talk 5
2. The GWCON prompt (+) is displayed on the console. If the prompt does not
appear when you first enter GWCON, press Return again.
3. At the GWCON prompt, enter the configuration command to see the protocols
and networks for which the router is configured. For example:
+configuration
