The
debug dialer
command indicates whether the multilink is up after authentication. As shown in Figure
, the
debug dialer
command also shows when the overload occurs.
Note: Click on the topology to view the command output.
If the second link fails to come up, use Table
to troubleshoot your MLP configuration.
Following are different debugging commands that are used to monitor
MLP in an ISDN DDR environment:
- The
debug ppp multilink
command displays packet sequence numbers. It is useful
only as a last resort because it does not help troubleshoot when connections are not being bundled.
- The debug ppp negotiation command displays the
Maximum-Receive-Reconstructed Unit (MRRU) option negotiation.
- The debug ppp authentication command is useful for displaying the steps in the PPP authentication process.
- The debug isdn events command also displays information that is useful for monitoring and troubleshooting
MLP.
