Cisco Catalyst 6500
The following example includes annotations that explain the requirements for successfully configuring NetFlow on this device.
ip route-cache flow
This command enables fast switching (CEF) on the device. On this device NetFlow is monitored only for traffic that is fast-switched (CEF).
mls ip multicast flow-stat-timer 9 mls aging long 64 mls aging normal 32 mls flow ip interface-full mls nde sender version 5
These Multilayer Switching commands set the named timer (ip multicast flow stat timer
), the aging intervals for data in the flow cache (aging long, aging normal
) by which export should occur, the flow mask (flow ip
); and also configure flow export (nde sender version
) as NetFlow version 5 on the Policy Feature Card (PFC).
ip flow-export source IP Address ip flow-export version 5 ip flow-export destination IP_Address(Orion NPM server) 2055 ip flow ingress layer2-switched vlan x, y, z (separate each VLAN with a comma) ip flow ingress
These commands do the following:
- Set the flow export source:
ip flow-export source
(the IP address must be monitored in SolarWinds Platform) - The flow version:
ip flow export version
- The flow export destination:
ip flow-export destination
(the IP of the SolarWinds Platform server with default port 2055) - Enable NetFlow:
ip flow ingress layer2-switched
for Layer 2 switched traffic and Layer 3 traffic-
ip flow ingress
on the Multilayer Switch Feature Card (MSFC)
Full configuration
The overall configuration without annotations looks like this:
ip route-cache flow mls ip multicast flow-stat-timer 9 mls aging long 64 mls aging normal 32 mls flow ip interface-full mls nde sender version 5 ip flow-export source IP Address ip flow-export version 5 ip flow-export destination IP_Address(Orion NPM server) 2055 ip flow ingress layer2-switched vlan x, y, z (separate each VLAN with a comma) ip flow ingress
