Configuration -WAN Access 6 PPP and MP configuration
6.9.5 Configuring the damping of the MP bundled links
Do as follows on the routers:
Step 1 Run:
system-view
The system view appears.
Step 2 Run:
interface mp-group number
The MP-Group interface view appears.
Step 3 Run:
ppp mp damping [ detect-time detect-time flapping-count flapping-count damping-time
damping-time ]
The command configures the damping function of the MP bundled links.
The damping function of the MP bundled links can damp the links that are in frequent
flapping. You can delete the damping only after the stability of the links satisfies the
requirements, so that the stability of the MP bandwidth is ensured.
If you run only the ppp mp damping commandn and you do not specify the optional
parameters, the MP bundled linksadopts the default value (bundled links flap once in 30
seconds), and the bundled links are damped After the bundled links are damped, the damping
deletes only when the time of the continuous Up status reaches 60 seconds.
