For calculating the number of classification entries per FC for a SAP in a VLL or vprn service, the
following rules apply:
•
•
Apply the rules to determine the number of classification entries per FC (only for the FCs in use)
using the following equation:
C(i)=ΣFCi(unicast)+FCi(multicast)+FCi(broadcast)+FCi(unknown_unicast)
i=nc,h1,ef,h2,l1,af,l2,be
where FCi (unicast), FCi (multicast), FCi (broadcast), and FCi (unknown-unicast) are set to a
value of 1 if this FC uses classifier to identify traffic-type unicast, multicast, broadcast and
unknown-unicast respectively. FCi (unicast), FCi (multicast), FCi (broadcast), and FCi (unknown-
unicast) are set to a value of 0 if this FC does not use a classifier to identify this traffic-type.
If the user does not configure meters explicitly for the FC and meter "11" is not created, the default
unicast meter is used for all traffic types and therefore, only one classification entry in hardware is
required by the FC. If the user does not configure meters explicitly for the FC and meter "11" is
created, the default unicast meter and multicast meter are used. Therefore by default, two
classification entries in hardware are required by a FC.
Taking into account the number of match criteria and the number of FCs used, use the equation
given below to arrive at total number of classification entries per policy, for example:

If a FC is in use and is created with an explicit unicast meter and explicit broadcast meter,
use these meters for unicast and broadcast traffic respectively and use meter #11
(assuming meter 11 is created by the user) for all other traffic types. This requires three
classification entries in hardware.
If a FC is in use and is created with an explicit unicast meter and explicit multicast meter,
use the unicast meter for unicast traffic and multicast meter for all other kinds of traffic.
This requires two classification entries in hardware.
If a FC is in use and is created with an explicit unicast meter, an explicit broadcast meter,
and an explicit multicast meter, use these meters for unicast, broadcast and multicast
traffic types respectively. Unknown unicast traffic type will use the explicitly defined
multicast meter. This requires three classification entries in hardware.
Multipoint meters cannot be used. Multipoint meter configured in a policy is not used
when the policy is applied to a SAP in an Epipe service.
All FCs in use and associated with a meter always use the unicast meter. Therefore, all
FCs in use utilize only one classification entry in the hardware.
