Description This command defines the reclassification actions that should be performed on any packet matching
the defined IP flow criteria within the entries match node. When defined under the ip-criteria context,
the reclassification only applies to IPv4 packets. When defined under the ipv6-criteria context, the
reclassification only applies to IPv6 packets.
If an egress packet on the SAP matches the specified IP flow entry, the forwarding class, or profile or
HSMDA or egress queue accounting behavior may be overridden. By default, the forwarding class and
profile of the packet is derived from ingress classification and profiling functions. The default behavior
for HSMDA queue accounting is to use the counters associated with the queue to which the packet is
mapped. Matching an IP flow reclassification entry will override all IP precedence or DSCP based
reclassification rule actions when an explicit reclassification action is defined for the entry.
It is also possible to redirect the egress packet to a configured policer. The forwarding class or profile
can also be optionally specified, but redirection to a policer is mutually exclusive with the hsmda-
counter-override keyword.
When an IP flow entry is first created, the entry will have no explicit behavior defined as the
reclassification actions to be performed. In show and info commands, the entry will display no action
as the specified reclassification action for the entry. When the entry is defined with no action, the entry
will not be populated in the IP flow reclassification list used to evaluate packets egressing a SAP with
the SAP egress policy defined. An IP flow reclassification entry is only added to the evaluation list
when the action command for the entry is executed either with explicit reclassification entries or
without any actions defined. Specifying action without any trailing reclassification actions allows
packets matching the entry to exit the evaluation list without matching entries lower in the list.
Executing no action on an entry removes the entry from the evaluation list and also removes any
explicitly defined reclassification actions associated with the entry.
The fc
keyword is optional. When specified, the egress classification rule will overwrite the forwarding
class derived from ingress. The new forwarding class is used for egress remarking and queue mapping
decisions.
The profile keyword is optional. When specified, the egress classification rule will overwrite the
profile of the packet derived from ingress. The new profile value is used for egress remarking and
queue congestion behavior.
