ppp keepalive adjustment

Function

The ppp keepalive adjustment command configures adjustment of the number of PPP detection times.

The undo ppp keepalive adjustment command disables adjustment of the number of PPP detection times.

By default, adjustment of the number of detection times is disabled.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

If the system is busy, for example, the CPU usage exceeds 80%, and the configured PPP detection interval is less than 40s, run the ppp keepalive adjustment system-state command so that the PPP detection interval is adjusted to a value twice the configured interval.

When inter-board Eth-Trunk member interfaces alternate between Up and Down, the device may not have a master processing board for a moment, causing user logouts. To clear the number of user detection failures after the board on which a trunk member interface resides becomes a master processing board so that users will stay online, run the ppp keepalive adjustment retransmit command. This function helps adjust the number of PPP detection times.

Configuration Impact

After the ppp keepalive adjustment retransmit command is run, if inter-board trunk member interfaces alternate between Up and Down, the number of user detection failures may be slightly greater than the configured ppp keepalive.

If the ppp keepalive adjustment command is run more than once in the same view, the latest configuration overrides the previous one.

Precautions

In VS mode, this command is supported only by the admin VS.
