sFlow scenario 2

In this scenario, two hosts connected to different switches send sFlow traffic to a collector. A LAG is used to connect the two switches. The physical topology of the network looks like this:

Procedure
  1. Configure switch 1.
    1. Enable sFlow globally. 
      switch#configswitch(config)#sflow
    2. Set the sFlow agent IP address to10.10.12.1. 
      switch(config)#sflow agent-ip 10.10.12.1
    3. Set the sFlow collector IP address to10.10.12.2. 
      switch(config)#sflow收集器10.10.12.2
    4. Configure sFLow sampling rate and polling interval. 
      switch(config)#sflow sampling 5000switch(config)#sflow polling 10
    5. Create VLAN8. 
      switch(config)#vlan 8switch(config-vlan-8)#no shutdownswitch(config)#exit
    6. Define LAG100and assign VLANvlan 8to it. 
      switch(config)#接口延迟100switch(config-lag-if)#no shutdownswitch(config-lag-if)#no routingswitch(config-lag-if)#vlan access 8switch(config-lag-if)#lacp mode active
    7. Configure interface1/1/1. 
      switch(config)#interface 1/1/1switch(config-if)#no shutdownswitch(config-lag-if)#no routingswitch(config-if)#vlan access 8
    8. Configure interface1/1/2and1/1/3as members of LAG100. 
      switch# (config)#interface 1/1/2switch(config-if)#no shutdownswitch(config-if)#延迟100switch(config-if)#exitswitch(config)-if#interface 1/1/3switch(config-if)#no shutdownswitch(config-if)#延迟100switch(config-if)#exit
    9. Configure interface1/1/4with IP address10.10.12.1/24. 
      switch# (config)#interface 1/1/4switch(config-if)#no shutdownswitch(config-if)#ip address 10.10.12.1/24switch(config-if)#quit
    10. Verify sFlow configuration. 
      switch#show sflowsFlow Global Configuration ----------------------------------------- sFlow enabled Collector IP/Port/Vrf 10.10.12.2/6343/default Agent Address 10.10.12.1 Sampling Rate 5000 Polling Interval 10 Header Size 128 Max Datagram Size 1400 sFlow Status ----------------------------------------- Running - Yes sFlow Statistics ----------------------------------------- Number of Samples 120
  2. Configure switch 2.
    1. Create VLAN8. 
      switch(config)#vlan 8switch(config-vlan-8)#no shutdownswitch(config)#exit
    2. Define LAG100and assign VLANvlan 8to it. 
      switch(config)#接口延迟100switch(config-lag-if)#no shutdownswitch(config-lag-if)#no routingswitch(config-lag-if)#vlan access 8switch(config-lag-if)#lacp mode active
    3. Configure interface1/1/1. 
      switch(config)#interface 1/1/1switch(config-if)#no shutdownswitch(config-lag-if)#no routingswitch(config-if)#vlan access 8
    4. Configure interface1/1/2and1/1/3as members of LAG100. 
      switch# (config)#interface 1/1/2switch(config-if)#no shutdownswitch(config-if)#延迟100switch(config-if)#exitswitch(config)-if#interface 1/1/3switch(config-if)#no shutdownswitch(config-if)#延迟100switch(config-if)#exit
