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:

On the 6400 Switch Series, interface identification differs.

Procedure

Configure switch 1.

Enable sFlow globally.
```
switch# config
switch(config)# sflow
```
Set the sFlow agent IP address to 10.10.12.1.
```
switch(config)# sflow agent-ip 10.10.12.1
```
Set the sFlow collector IP address to 10.10.12.2.
```
switch(config)# sflow collector 10.10.12.2
```

Configure sFLow sampling rate and polling interval.

switch(config)# sflow sampling 5000
switch(config)# sflow polling 10

Create VLAN 8.

switch(config)# vlan 8
switch(config-vlan-8)# no shutdown
switch(config)# exit

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)# vlan access 8
switch(config-lag-if)# lacp mode active

Configure interface 1/1/1.

switch(config)# interface 1/1/1
switch(config-if)# no shutdown 
switch(config-if)# vlan access 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

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

Verify sFlow configuration.

switch# show sflow

Configure switch 2.

Create VLAN 8.

switch(config)# vlan 8
switch(config-vlan-8)# no shutdown
switch(config)# exit

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)# vlan access 8
switch(config-lag-if)# lacp mode active

Configure interface 1/1/1.

switch(config)# interface 1/1/1
switch(config-if)# no shutdown 
switch(config-if)# vlan access 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
