Licensing Requirements and Limitations for VPN QoS

Licensing Requirements and Limitations for VPN QoS

Licensing Requirements

This feature is a basic feature and is not under license control.

Restrictions and Guidelines

Restrictions

Guidelines

Impact

When the public network tunnel for VPN QoS is a TE tunnel, a TE tunnel change (for example, the TE HSB LSP becomes Down or Up) may cause some VPN packets to be lost.

None

The function cannot be implemented.

Layer 2 multicast does not support VPLS QoS.

Enable HQoS on interfaces.

Layer 2 multicast and VPLS QoS are mutually exclusive.

PBB VSIs do not support VPLS QoS.

Enable HQoS on interfaces.

PBB VPLS and VPLS QoS are mutually exclusive.

Only one outbound interface of an SR-TE node tunnel supports VPN QoS.

None

Accuracy of VPN QoS of SR-TE node tunnels is affected.

Only the TE-HSB scenario supports VPN QoS for backup links.

None

Availability of VPN QoS after an active/standby switchover in a non-TE-HSB protection scenario is affected.

On LPUF-50/LPUF-50-Lboards:
  • Downstream HQoS is not supported when the LPUF-50/LPUF-50-L TM BUM traffic egress is Trunk/Global-VE.
  • When the LPUF-50/LPUF-50-L TM BUM traffic egress is an APS protection interface (for example, trunk-serial/global-mp-group/pos-trunk), if the interface's two members are on the same TM, the backup interface traffic does not support downstream HQoS.

None

The function cannot be implemented.

If the TM is the LPUF-480/LPUF-480-B/LPUI-480/LPUI-480-B/LPUI-480-L/LPUF-480-E/LPUI-480-CM/LPUI-200/LPUI-200-L/LPUF-200/LPUF-200-B/LPUI-1T/LPUI-1T-B/LPUI-1T-L/LPUI-1T-CM board and the egress at the network side is a cross-interface egress, bandwidth limitation and bandwidth assurance must be implemented for each interface.

None

The function cannot be implemented.

VPLS PW HQoS/VLL PW HQoS does not support load balancing among BGP LSPs.

None

When an HQoS-enabled VPLS/VLL PW is iterated to two or more BGP LSPs, only one BGP LSP is selected for forwarding.
