pppoa set transport headers hdlc
16.18.1 Syntax
pppoa set transport {<name>|<number>} headers hdlc
{enabled|disabled}
16.18.2 Description
This command allows you to enable/disable whether your system can transmit
and receive packets containing HDLC headers. If you want LLC packets to be
transmitted and received instead of/as well as HDLC packets, use the
pppoa
set transport headers llc enabled
command.
When both HDLC and LLC headers are disabled, the default encapsulation
method is VC multiplexed (VC Mux). PPP determines which format to use to
transmit/receive packets by ‘learning’ the format information from incoming
packets.
