Usage guidelines
Because it is possible that some response frames received with the Final bit set to 1 may be falsely treated
as unsolicited response frames, HP recommends that you use the default setting to prevent link flapping
caused by false link re-negotiations that result.
Examples
# Enable LAPB to initiate link re-negotiation when receiving unsolicited response frames on Serial 2/0.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] lapb pollremote
