link via IPCP extensions. This command is only applicable if the associated SAP or port is a PPP/
MLPPP interface with an IPCP encapsulation.

end of the associated PPP/MLPPP link via IPCP extensions

ethernet
Syntax ethernet
Context config>service>epipe>sap
Description Use this command to configure Ethernet properties for the SAP.
llf
Syntax [no] llf
Context config>service>epipe>sap>ethernet
Description This command enables Link Loss Forwarding (LLF) on an Ethernet port. LLF can only be enabled on
Ethernet ports configured for null encapsulation.
LLF provides an end-to-end OAM fault notification for Ethernet VLL service. When LLF is enabled
and there is a local fault on the pseudowire or service, or a remote fault on the SAP or pseudowire, the
Ethernet port is brought down. Using label withdrawal or T-LDP status bits, LLF signals to connected
equipment that the VLL is down. LLF stops signaling when the fault disappears.
The no form of the command disables LLF.
