Configuration guidelines
• The sampling interval configured in MPLS view applies to all MPLS TE tunnels. The output rates of all
MPLS TE tunnels are recorded every sampling interval to calculate the actual average bandwidth of
an MPLS TE tunnel in one sampling interval.
• Once the mpls te auto-bandwidth adjustment frequency command you configured in MPLS TE
tunnel interface view takes effect, an adjustment frequency timer starts. Upon expiration of this timer,
MPLS TE resizes the tunnel bandwidth using the maximum tunnel output rate sampled before the
expiration of the timer as the bandwidth constraint to set up a new LSP tunnel. If the setup attempt
succeeds, traffic is switched to the new LSP tunnel and the old LSP tunnel is cleared. If the setup
attempt fails, traffic travels the existing LSP tunnel.
• When resetting the automatic bandwidth adjustment function, the system clears information about
output rate sampling and the remaining time for next bandwidth optimization.
