Table 6: Forwarding Class and Enqueuing Priority Classification Hierarchy Based on Rule Type
# Rule
5 dscp dscp-name
6 IP criteria: Multiple
entries per policy
Multiple criteria per
entry
7 MAC criteria: Multi-
ple entries per policy
Multiple criteria per
entry
The IP and MAC match criteria can be very basic or quite detailed. IP and MAC match criteria are
constructed from policy entries. An entry is identified by a unique, numerical entry ID. A single
entry cannot contain more than one match value for each match criteria. Each match entry has
action which specifies: the forwarding class of packets that match the entry.
The entries are evaluated in numerical order based on the entry ID from the lowest to highest ID
value. The first entry that matches all match criteria has its action performed.
list the supported IP and MAC match criteria.

Forwarding Class
Set when an fc-name
exists in the policy. Other-
wise, preserve from the
previous match.
Set when an fc-name
exists in the entry's action.
Otherwise, preserve from
the previous match.
Set when an fc-name
exists in the entry's action.
Otherwise, preserve from
the previous match.
Enqueuing Priority
Set when the priority
parameter is high or low in
the entry. Otherwise, pre-
serve from the previous
match.
Set when the priority
parameter is high or low in
the entry action. Other-
wise, preserve from the
previous match.
Set when the priority
parameter is specified as
high or low in the entry
action. Otherwise, pre-
serve from the previous
match.

Comments
Each dscp-name that defines the
DSCP value must be explicitly
defined. Each packet can only match
a single DSCP rule.
When IP criteria is specified, entries
are matched based on ascending
order until first match and then pro-
cessing stops. A packet can only
match a single IP criteria entry.
When MAC criteria is specified,
entries are matched based on
ascending order until first match and
then processing stops. A packet can
only match a single MAC criteria
entry.
