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):
TC= Σ 2 * E(i)
i=nc,h1,ef,h2,l1,af,l2,be
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.
Resource Allocation for Network QoS policy for 7210 SAS-K
The queues required for access-uplink port egress is allocated for the egress queue system pool.
Queues from the egress queue system pool are allocated for per SAP egress queues and per access-
uplink port egress queues.
The Dot1p policy and DSCP policy resources used for network qos ingress FC assignment, is
shared with the per SAP ingress classification criteria from the system pool.
