Connectivity Guide

Instead of PFC, you can congure LLFC as follows:
NOS# configure terminal
NOS(config)# class-map type network-qos llfc
NOS(config-cmap-nqos)# match qos-group 0-7
NOS(config-cmap-nqos)# exit
NOS(config)# policy-map type network-qos llfc
NOS(config-pmap-network-qos)# class llfc
NOS(config-pmap-c-nqos)# pause buffer-size 100 pause-threshold 50 resume-threshold 10
NOS(config-pmap-c-nqos)# end
NOS# configure terminal
NOS(config)# interface range ethernet 1/1/1,1/1/2,1/1/3
NOS(conf-range-eth1/1/1,1/1/2,1/1/3)# flowcontrol transmit on
NOS(conf-range-eth1/1/1,1/1/2,1/1/3)# flowcontrol receive on
NOS(conf-range-eth1/1/1,1/1/2,1/1/3)# service-policy input type network-qos llfc
NOS(conf-range-eth1/1/1,1/1/2,1/1/3)# end

Buer statistics tracking
OS10 oers the Buer Statistics Tracking (BST) feature to observe buer usage across the switch without any impact to performance.
This feature maintains separate sets of counters for buer usage accounting:
Ingress priority-group
Ingress service-pool
Ingress shared-headroom-pool
Egress queue
Egress service-pool
