73.4.10 encapsulation
This command defines the type of IP encapsulation used on an ATM sub-interface.
Syntax
interface atm <group-id>/<sub-id>
encapsulation {ipoa|ethoa|pppoa}-{mux|snap}
encapsulation pppoe
encapsulation pppoe-mux
Command Description
ipoa Selects the IP-over-ATM, in RFC 2684 "Routed" mode.
ethoa Selects the Ethernet-over-ATM, in RFC 2684 "Bridged"
mode.
pppoa Selects PPP over ATM client (defined in RFC 2364)
snap Selects AAL5 LLC/SNAP mode. A LLC header is used to
describe the type of payload transmitted
mux Selects AAL5 VC-multiplexed mode, data is not prepended
with an LLC header
pppoe
Selects PPPoE over ATM in LLC/SNAP mode (i.e., PPPoE
client on top of ethoa-snap encapsulation)
pppoe-mux Selects PPPoE over ATM in VC-multiplexed mode (PPPoE
client on top of ethoa-mux encapsulation)
Default
By default, no ATM interfaces are defined.
Command Mode
Privileged User
Example
This example defines an ATM interface with RFC 2684 "Routed" encapsulation, with
LLC/SNAP headers:
(conf-atm0/0)# encapsulation ipoa-snap
