I need to configure flow-export in exos. How to configure it?
Following is the config on cisco -
ip flow-export source Vlan1 |
ip flow-export version 5 |
ip flow-export destination 172.16.202.47 2055 |
ip flow-export destination 172.30.250.242 9996 |
ip flow-top-talkers |
top 50 |
sort-by bytes |
Solved! Go to Solution.

Hi,
EXOS uses sflow which is described in the article below:

I THINK Netflow is proprietary to Cisco(or was) so the commands/syntax may not 100% check out. I also THINK(not 100% sure) they do netflow in software. Below would be a semi common sflow example:
• Configures the sampling rate on an edge port.
• Enables sFlow on the edge port.
• Enables sFlow globally on the switch.
configure sflow collector 10.127.11.88 vr vr-mgmt
configure sflow ports 5:21 sample-rate 8192
enable sflow ports 5:21 egress
enable sflow
Here is sample output for the configuration:
SFLOW Global Configuration
Global Status: enabled
Polling interval: 20
Sampling rate: 8192
Maximum cpu sample limit: 2000
SFLOW Configured Agent IP: 0.0.0.0
Operational Agent IP: 10.127.11.88
Collectors
SFLOW Port Configuration Port Status Sample-rate Subsampling Sflow-type
Config / Actual factor Ingress/Egress
5:21 enabled 8192 / 8192 1 Disabled / Enabled
Displaying sFlow
Not sure how this lines up with Cisco but your configuration options would be these below:
configure sflow max-cpu-sample-limit # default is 2000 samples per second
configure sflow poll-interval # default is 20 seconds
configure sflow ports sample-rate # The default number is 8192, unless modified by the configure sflow sample-rate command below.
configure sflow sample-rate # The default number is 8192, unless modified by the configure sflow sample-rate command.

Hi Chris,
Thank you for the prompt response.
Do we have any syntax in exos for hardware based flows. Like in cisco we use following commands to enable hardware based flows.
mls aging long 64 |
mls aging normal 32 |
mls netflow interface |
mls flow ip interface-full |
mls nde sender version 5 |
mls qos |
mls cef error action reset |
