pointtopoint
Creates virtual ATM
point-to-point subinterface
Edmonton(config-if)#pvc 1/2 Assigns virtual circuit
(VC) 2 on virtual path 1
to the subinterface
NOTE: pvc 1/2 is an
example value that must
be changed to match the
value used by the ISP.
Edmonton(config-if)#dialer pool-member 1 Links the ATM interface to
the dialer interface
Edmonton(config-if)#encapsulation aal5mux Con?¬?gures the ATM
adaptation layer (AAL) for
multiplex (MUX)-type
VCs
NOTE: The global
default encapsulation
option is aal5snap.
Con?¬?guring PPPoA 13
Step 2: Con?¬?gure the Dialer Interface
For Password Authentication Protocol (PAP)
For Challenge Handshake Authentication Protocol (CHAP)
Edmonton(config)#interface dialer0 Enters interface mode
NOTE: When
con?¬?guring the dialer
interface in an ATM
environment, it is
not necessary to
con?¬?gure the maximum
transmission unit (MTU)
and adjust the MSS. This
is required only when
con?¬?guring PPPoE.
Edmonton(config-if)#ip address negotiated Obtains IP address via
PPP/IPCP address
negotiation
Edmonton(config-if)#encapsulation ppp Enables PPP encapsulation
on the dialer interface
Edmonton(config-if)#dialer pool 1 Links the dialer interface
with the physical interface
ATM 0/0
Edmonton(config-if)#ppp authentication pap
callin
Uses PAP for authentication
Edmonton(config-if)#ppp pap sent-username
pieman password bananacream
Enables outbound PAP
user authentication
Edmonton(config-if)#ppp authentication chap
callin
Enables outbound CHAP
user authentication
Edmonton(config-if)#ppp chap hostname pieman Submits the CHAP
username
Edmonton(config-if)#ppp chap password
bananacream
Submits the CHAP
password
Edmonton(config-if)#exit Returns to global
con?¬?guration mode
14 Con?¬?guring PPPoA
Step 3: Verify a PPPoA Connection
Edmonton#debug pppatm event vc 1/2 Displays events on virtual
circuit 2 on virtual path 1
Edmonton#debug pppatm error vc 1/2 Displays errors on virtual
circuit 2 on virtual path 1
Edmonton#show atm interface atm0/0 Displays ATM-speci?¬?c
information about an ATM
interface
Edmonton#show dsl interface atm0/0.
