entries in hardware. If default multipoint meter 9 is not configured, then the FC will use the unicast
meter for all traffic types. In this case, the FC requires a single classification entry 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.
Given 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 TC):
Where,
E(i) is the number of match- criteria entries that classify packets to FCi. For 7210 platforms, the
maximum number of classification entries per policy can be 64 (including default).
2 is the number of classification entries that are required by FCi.
Note: In the worst case, only 2 classification entries are used per FC in a network policy, as only
two traffic-types are supported.
Determine number of policers or meters to use (for example TP). A maximum of 16 meters per
network policy is available.
Only those meters that are associated with FCs need to be considered for number of meters. Note,
that only FCs in use are considered.
