Connectivity Guide
Instead of PFC, you can congure 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

OS10# configure terminal
OS10(config)# dcbx enable
Buer statistics tracking
OS10 oers the Buer Statistics Tracking (BST) feature to observe buer usage across the switch without any impact to performance.
This feature maintains separate sets of counters for buer usage accounting:
• Ingress priority-group
• Ingress service-pool
• Ingress shared-headroom-pool
• Egress queue
• Egress service-pool
