packets flow in VLANs

I want to check the packet flow in subinterfaces. Is there any other command than sh VLANs?

I want to see if round robin load balancing is happening in the subinterfaces.

sh VLans output is as follows:

Vlan ID 10

Protocol Configured IP

Address W.X.Y.Z

Recieved 155083

Transmitted 82970

Vlan ID 20

Protocol Configured IP

Address W.X.Y1.Z

Recieved 1198

Transmitted 51328

It seems that one of the subinterfaces transmites and recieves more than the other.

Can anyone please help me if there are other ways to check the packet flow in VLANs ?

I am not sure what you mean by load balancing. You have two vlans which have unique traffic flow characteristics. The traffic flow is based on the traffic for the vlan.

Dear tigist,

as there is IP address configured on the SVI interfaces for each VLAN, just enable Netflow by use --> ip route-cache flow - under the SVI interface (Interface Vlan10, interface VLAN20) then you can catch the traffic vlow from each of VLANS by using show ip cache flow.

Here is the config:

Interface vlan10

ip address x.x.x.x

ip route-cache flow

Interface vlan20

ip address x.x.x.x

ip route-cache flow

r1#show ip cache flow

Please rate helpful posts.

Best Regards,
