ipv6-criteria
Syntax [no] ipv6-criteria
Context config>qos>sap-egress
config>qos>sap-ingress
Description
IPv6 criteria-based SAP egress/ingress policies are used to select the appropriate ingress queue and
corresponding forwarding class for matched traffic.
This command is used to enter the node to create or edit policy entries that specify IPv6 criteria such as IP
quintuple lookup or DiffServ code point.
The OS implementation will exit on the first match found and execute the actions in accordance with the
accompanying action command. For this reason entries must be sequenced correctly from most to least
explicit.
The no form of this command deletes all the entries specified under this node. Once ipv6-criteria entries are
removed from a SAP ingress policy, the ipv6-criteria is removed from all services where that policy is
applied.
lsp-exp
Syntax lsp-exp lsp-exp-value [fc fc-name] [priority {low|high}] [hsmda-counter-override counter-id]
no lsp-exp lsp-exp-value
Context config>qos>sap-ingress
Description
This command explicitly sets the forwarding class or sub-class enqueuing priority when a packet is marked
with a MPLS EXP bits specified. Adding a lsp-exp rule on the policy forces packets that match the MPLS
LSP EXP specified to override the forwarding class and enqueuing priority based on the parameters
included in the lsp-exp rule. When the forwarding class is not specified in the rule, a matching packet
preserves (or inherits) the existing forwarding class derived from earlier matches in the classification
hierarchy. When the enqueuing priority is not specified in the rule, a matching packet preserves (or inherits)
the existing enqueuing priority derived from earlier matches in the classification hierarchy..
The lsp-exp-value is derived from the MPLS LSP EXP bits of the top label.
Multiple commands can be entered to define the association of some or all eight LSP EX bit values to the
forwarding class.
The no form of this command removes the explicit lsp-exp classification rule from the SAP ingress policy.
Removing the rule on the policy immediately removes the rule on all ingress SAPs using the policy.
This command applies to Ethernet Layer 2 SAPs only.
Default
none
Parameters
lsp-exp-value — This value is a required parameter that specifies the unique MPLS LSP EXP value that will
match the lsp-exp rule. If the command is executed multiple times with the same lsp-exp-value, the
previous forwarding class and enqueuing priority is completely overridden by the new parameters or
defined to be inherited when a forwarding class or enqueuing priority parameter is missing.
