Fc Mapping Based On Exp Bits - Alcatel-Lucent 7450 Quality Of Service Manual

Service Ingress QoS Policy
Ingress VNI classification is applicable to all Ethernet SAPs, except for PW-SAPs, B-VPLS
SAPs, and CCAG SAPs, in any applicable service. The feature is supported on FP2- and
higher-based hardware.
The following restrictions also apply:

FC Mapping Based on EXP Bits

You can use the lsp-exp command to set your sap-ingress qos policy on Ethernet L2 SAPs to
perform FC mapping based on EXP bits.
The lsp-exp option causes the forwarding class and drop priority of incoming traffic to be
determined by the mapping result of the EXP bits in the top label.
The following example displays FC mapping based on EXP bits:

• Source and destination port matching on a SAP on which a SAP ingress QoS policy
is applied that has ip-criteria or ipv6-criteria statements with type vxlan-vni, is not
available for:
→ IPv4 QoS classification for VXLAN or VXLAN GPE traffic
→ IPv6 QoS and filter classification for VXLAN or VXLAN GPE traffic
If the criteria type is set to vxlan-vni and if source or destination port matching
entries are configured in an IPv4 or IPv6 SAP ingress QoS policy or in an IPv6 filter
policy, any VXLAN or VXLAN GPE ingress traffic will not match these entries on
the SAP on which the SAP ingress QoS policy is applied.
• The simultaneous configuration on a SAP of a QoS policy containing an ip-criteria
entry with type vxlan-vni and of a MAC filter with type vid is not supported, and
vice versa.
This is only applicable to Epipe and VPLS services.
• If a SAP ingress QoS policy that has ip-criteria or ipv6-criteria statements with
type vxlan-vni is applied to a SAP, any ip-criteria or ipv6-criteria entry match
vxlan-vni statements will not match:
→ IPv4 packets containing options
→ IPv6 packets containing extension headers
→ Ingress 802.1ah PBB frames
→ IPv6 over PPPoE traffic received with more than one VLAN tag
→ Non-first fragments of an IPv4 or IPv6 fragmented packet
• The configuration of a SAP ingress QoS policy containing ip-criteria or ipv6-
criteria entry match vxlan-vni statements is not supported within an SLA profile.
