Chapter 1: Review
There are no commands from Chapter 1.
Chapter 2: WANs
debug ppp | Displays information on traffic and exchanges in an internetwork implementing Point-to-Point Protocol (PPP).
encapsulation ppp | Sets PPP as the encapsulation method used by a serial or ISDN interface.
interface | Configures an interface type and enters interface configuration mode.

Chapter 3: WAN Design
There are no commands from Chapter 3.
Chapter 4: Point-to-Point-Protocol
encapsulation ppp | Sets PPP as the encapsulation method used by a serial or ISDN interface.
ppp authentication | Enables Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP) or both, and specifies the order in which CHAP and PAP authentication are selected on the interface.
ppp chap hostname | Creates a pool of dialup routers that all appear to be the same host when authenticating with CHAP.
ppp chap password | Configures a password that will be sent to hosts that want to authenticate the router. This command limits the number of username/password entries in the router.
ppp pap sent-username | Enables remote PAP support for an interface and uses sent-username and password in the PAP authentication request packet to the peer.
show interfaces | Displays statistics for all interfaces configured on the router or access server.
username password | Specifies the password to be used in CHAP caller identification and PAP.
Chapter 5: Integrated Services Digital Network (ISDN)
clear interface | Resets the hardware logic on an interface.
debug dialer | Shows such information as what number the interface is dialing.
debug isdn q921 | Displays data link-layer (Layer 2) access procedures that are taking place at the router on the D channel (LAPD) of its Integrated Services Digital Network (ISDN) interface.
dialer idle-timeout | Specifies the idle time before the line is disconnected.
dialer map | Configures a serial interface to call one or multiple sites.
dialer wait-for-carrier-time | Specifies how long to wait for a carrier.
dialer-group | Controls access by configuring an interface to belong to a specific dialing group.
dialer-list protocol | Defines a DDR dialer list to control dialing by protocol or by a combination of protocol and ACL.
encapsulation ppp | Sets PPP as the encapsulation method used by a serial or ISDN interface.
interface | Configures an interface type and enters interface configuration mode.
isdn spid1 | Defines at the router the service profile identifier (SPID) number that has been assigned by the ISDN service provider for the B1 channel.
isdn spid2 | Defines at the router the SPID number that has been assigned by the ISDN service provider for the B2 channel.
isdn switch-type | Specifies the central office switch type on the ISDN interface.
ping | Sends ICMP echo request packets to another node on the network. Checks host reachability and network connectivity. Diagnoses basic network connectivity.
ppp authentication | Enables Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP) or both, and specifies the order in which CHAP and PAP authentication are selected on the interface.
show dialer | Displays general diagnostics for serial interfaces configured for DDR.
show interfaces | Displays statistics for all interfaces configured on the router or access server.
show ip route | Displays the current state of the routing table.
show isdn active | Displays current call information, including called number, the time until the call is disconnected, AOC charging units used during the call, and whether the AOC information is provided during calls or at the end of calls.
show isdn status | Displays the status of all ISDN interfaces or, optionally, a specific digital signal link (DSL) or a specific ISDN interface.
show status | Displays the current status of the ISDN line and both B channels.
Chapter 6: Frame Relay
enable password | Specifies a password to prevent unauthorized access to the router.
encapsulation frame-relay | Enables Frame Relay encapsulation.
end | Exits configuration mode.
exec-timeout | Sets the interval that the EXEC command interpreter waits until user input is detected.
exit | Exits any configuration mode or closes an active terminal session and terminates the EXEC.
frame-relay local-dlci | Enables the Local Management Interface (LMI) mechanism for serial lines using Frame Relay encapsulation.
hostname | Configures the router with a host name, which is used in prompts and default configuration filenames.
interface serial | Selects the interface and enters interface configuration mode.
ip address | Sets the logical network address of the interface.
ip unnumbered | Enables Internet Protocol (IP) processing on a serial interface without assigning an explicit IP address to the interface.
ipx network | Enables Internetwork Packet Exchange (IPX) routing on a particular interface and optionally selects the type of encapsulation (framing).
keepalive | Enables the LMI mechanism for serial lines using Frame Relay encapsulation.
line console | Configures a console port line.
line vty | Specifies a virtual terminal for remote console access.
login | Enables password checking at terminal session login.
ping | Sends ICMP echo request packets to another node on the network. Checks host reachability and network connectivity. Diagnoses basic network connectivity.
show frame-relay lmi | Displays statistics about the LMI.
show frame-relay map | Displays the current map entries and information about the connections.
show frame-relay pvc | Displays statistics about PVCs for Frame Relay interfaces.
show interfaces serial | Displays information about a serial interface.
