HP MSR2000/3000/4000 Router Series Interface Command Reference

45
protocol: Configures the interface to operate in protocol mode. In this mode, the interface uses
configured link layer protocol parameters to set up a link with the remote end after its physical link is
established.
Usage guidelines
You can configure this command for a synchronous/asynchronous interface only after you change the
mode of the interface to asynchronous mode with the physical-mode async command. You can configure
PPP when the asynchronous serial interface is operating in flow mode, but the configuration does not take
effect. The PPP configuration takes effect only after you change the operating mode of the interface to
protocol.
Examples
# Configure asynchronous serial interface Async 6/4/0 to operate in flow mode.
<Sysname> system-view
[Sysname] interface async 6/4/0
[Sysname-Async6/4/0] async-mode flow
# Configure synchronous/asynchronous serial interface Serial 2/0 to operate in flow mode.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] async-mode flow
