You can perform Cisco Catalyst 9300-48U configuration using the following steps:

flow record NFARecordinput

match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match ipv4 protocol
match interface input
match ipv4 tos
match flow direction
collect interface output
collect counter bytes long
collect counter packets long
collect transport tcp flags
collect timestamp absolute first
collect timestamp absolute last

flow record NFARecordoutput

match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match ipv4 protocol
match interface output
match ipv4 tos
match flow direction
collect interface input
collect counter bytes long
collect counter packets long
collect transport tcp flags
collect timestamp absolute first
collect timestamp absolute last

flow exporter NFAExporter
destination {NETFLOW_SERVER_IP}
source {LOOPBACK_INTERFACE_NAME}
transport udp {NETFLOW_SERVER_LISTENER_PORT}
template data timeout 60

flow monitor NFAMonitorinput
exporter NFAExporter
record NFARecordinput
cache timeout active 60

flow monitor NFAMonitoroutput
exporter NFAExporter
record NFARecordoutput
cache timeout active 60


Enter global configuration mode on the router or MSFC, and issue the following commands for each interface on which you want to enable flow:

interface {INTERFACE_NAME}
ip flow monitor NFAMonitorinput input
ip flow monitor NFAMonitoroutput output


Post configuration, you can discover your device by navigating to Inventory > Devices or Network > Flow Analysis
