LLFC configuration — ToR device
Instead of PFC, you can configure 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
WRED/ECN configuration — ToR device
NOS# configure terminal
NOS(config)# wred w1
NOS(config-wred)# random-detect ecn
NOS(config-wred)# random-detect color green minimum-threshold 100 maximum-threshold 500
