Example: Configuring CoS on Static LSQ MLPPP Bundle Interfaces
This example shows how to configure dynamic subscriber services on MLPPP bundle interfaces. The MLPPP bundles must be configured on link services intelligent queuing (IQ) (LSQ) interfaces. The MLPPP interfaces must be statically configured.
To configure dynamic subscriber services on static LSQ MLPPP bundle interfaces:
Configure class of service features for the LSQ interfaces.
