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# config
      switch(config)# sflow
    2. Set the sFlow agent IP address to 10.10.12.1.
      switch(config)# sflow agent-ip 10.10.12.1
    3. Set the sFlow collector IP address to 10.10.12.2.
      switch(config)# sflow collector 10.10.12.2
    4. Configure sFLow sampling rate and polling interval.
      switch(config)# sflow sampling 5000
      switch(config)# sflow polling 10
    5. Create VLAN 8.
      switch(config)# vlan 8
      switch(config-vlan-8)# no shutdown
      switch(config)# exit
    6. Define LAG 100 and assign VLAN vlan 8 to it.
      switch(config)# interface lag 100 
      switch(config-lag-if)# no shutdown 
      switch(config-lag-if)# no routing
      switch(config-lag-if)# vlan access 8
      switch(config-lag-if)# lacp mode active
    7. Configure interface 1/1/1.
      switch(config)# interface 1/1/1
      switch(config-if)# no shutdown 
      switch(config-lag-if)# no routing
      switch(config-if)# vlan access 8
    8. Configure interface 1/1/2 and 1/1/3 as members of LAG 100.
      switch# (config)#interface 1/1/2
      switch(config-if)# no shutdown
      switch(config-if)# lag 100
      switch(config-if)# exit
      switch(config)-if# interface 1/1/3
      switch(config-if)# no shutdown
      switch(config-if)# lag 100
      switch(config-if)# exit
    9. Configure interface 1/1/4 with IP address 10.10.12.1/24.
      switch# (config)#interface 1/1/4
      switch(config-if)# no shutdown
      switch(config-if)# ip address 10.10.12.1/24
      switch(config-if)# quit
    10. Verify sFlow configuration.
      switch# show sflow

  2. Configure switch 2.
    1. Create VLAN 8.
      switch(config)# vlan 8
      switch(config-vlan-8)# no shutdown
      switch(config)# exit
    2. Define LAG 100 and assign VLAN vlan 8 to it.
      switch(config)# interface lag 100 
      switch(config-lag-if)# no shutdown 
      switch(config-lag-if)# no routing
      switch(config-lag-if)# vlan access 8
      switch(config-lag-if)# lacp mode active
    3. Configure interface 1/1/1.
      switch(config)# interface 1/1/1
      switch(config-if)# no shutdown 
      switch(config-lag-if)# no routing
      switch(config-if)# vlan access 8
    4. Configure interface 1/1/2 and 1/1/3 as members of LAG 100.
      switch# (config)#interface 1/1/2
      switch(config-if)# no shutdown
      switch(config-if)# lag 100
      switch(config-if)# exit
      switch(config)-if# interface 1/1/3
      switch(config-if)# no shutdown
      switch(config-if)# lag 100
      switch(config-if)# exit
