Frame Relay DLCI and ATM Restrictions

Frame Relay DLCI and ATM Restrictions

Restrictions of AutoQoS on Frame Relay DLCIs and ATM PVCs are

  • AutoQoS cannot be implemented on a DLCI if a map class is attached to the DLCI.

  • AutoQoS cannot be implemented on a low-speed DLCI (768 kbps or lower) if a virtual template is already configured for the DLCI.

  • If a Frame Relay DLCI is already assigned to one subinterface, you cannot configure AutoQoS VoIP from a different subinterface.

  • For a low-speed DLCI (768 kbps or lower) configured with FR-to-ATM internetworking, MLP is configured automatically; the subinterface must have an IP address.

  • When MLP over FR is configured, the IP address is removed and placed on the MLP bundle.

  • AutoQoS cannot be implemented on a low-speed ATM PVC if a virtual template is already configured for the ATM PVC.

  • For a low-speed ATM PVC, MLP over ATM is configured automatically; the subinterface must have an IP address.

  • When MLP over ATM is configured, the IP address is removed and placed on the MLP bundle
