Examples
host1(config)#interface atm 0/1.19
host1(config)#interface atm 0/0/1.19
Use the no version to remove the interface or subinterface.
See interface atm.
Use to assign an IP address and subnet mask to a subinterface.
Example
host1(config-if)#ip address 192.1.1.1 255.255.255.0
Use the no version to remove an IP address or disable IP processing.
See ip address.
Use to configure an access concentrator (AC) name on the PPPoE interface. When
the AC (the server) receives a PPPoE Active Discovery Initiation (PADI) packet that it
can serve, it replies by sending a PPPoE Active Discovery Offer (PADO) packet. The
PADO packet contains the AC name configured using this command.
If the AC name is not configured, the router name is used.
The AC name can be a maximum of 64 characters.
Example
host1(config-subif)#pppoe acName CYM9876
Use the no version to remove the AC name.
See pppoe acName.
Use to prevent a client from establishing more than one session using the same MAC
address.
This feature is disabled by default.
For PPPoE sessions that contain the IWF-Session DSL Forum VSA (26-254) in the
PADR packets sent from the client to the PPPoE access concentrator, multiple
subscriber sessions with the same MAC address can originate. This behavior occurs
because the interworking functionality (IWF) causes a PPPoE over ATM or PPP over
ATM (PPPoA) session to be converted by the digital subscriber line access multiplexer
(DSLAM) into a PPPoE session. As a result of this conversion, the MAC addresses of
all IWF PPPoE sessions contain the MAC address of the DSLAM device.
For PPPoE sessions with the IWF-Session VSA, duplication of MAC addresses is
permitted by default. Regardless of whether the duplicate protection feature is enabled,
