Timer-Hold Retry - H3C MSR810 Command Reference Manual

Usage guidelines
On an interface encapsulated with PPP, the data link layer sends keepalive packets at keepalive
intervals to detect the availability of the remote end. The data link layer determines that the peer end
is down if it has not received any keepalive messages when the keepalive retry limit is reached. The
data link layer then reports the link down event to the upper-layer protocols.
To set the keepalive retry limit, use the timer-hold retry command.
On a s low link, increase the keepalive interval to prevent false shutdown of the interface. This
situation might occur when keepalive packets are delayed because a l arge packet is being
transmitted on the link.
Examples
# Set the keepalive interval to 1000 seconds on Dialer 1.
<Sysname> system-view
[Sysname] interface dialer 1
[Sysname-Dialer1] timer-hold 1000

Usage guidelines
The interface determines that the remote end is down if it has not received a keepalive response
when the keepalive retry limit is reached.
On a s low link, increase the keepalive retry limit to prevent false shutdown of the interface. This
situation might occur when keepalive packets are delayed because a l arge packet is being
transmitted on the link.
