sFlow – Traffic analysis protocol, similar to NetFlow.
Enable/disable sFlow on the switch:
enable/disable sflow
Viewing parameters:
show sflow show sflow flow_sampler show sflow counter_poller show sflow analyzer_server
Adding/modifying the sFlow analyzer server:
create/config sflow analyzer_server 1-4 owner NAME timeout 1-2000000(sec)/infinite collectoraddress ADDRESS collectorport udp_PORT maxdatagramsize 300-1400
Example of removing the sFlow analyzer server:
delete sflow analyzer_server 1-4
Creating, modifying, deleting the sFlow polling counters:
create/config sflow counter_poller ports NUMBER/all analyzer_server_id 1-4 interval disable/20-120(sec) delete sflow counter_poller ports NUMBER/all
Create, modify, delete sFlow sample ports:
create/config sflow flow_sampler ports NUMBER/all analyzer_server_id (1-4) rate value 0-65535 tx_rate value 0-65535 maxheadersize value 18-256 delete sflow flow_sampler ports NUMBER/all
I will give an example of setting:
enable sflow create sflow analyzer_server 1 owner Linux collectoraddress 192.168.1.5 collectorport 6343 create sflow counter_poller ports 1 analyzer_server_id 1 interval 20 create sflow flow_sampler ports 1:1 analyzer_server_id 1 rate 1000 maxheadersize 128
