Bandwidth usage on a router

Unanswered Question
Dec 5th, 2010

I have this camera connected to a router. How can I tell how much bandwidth a video clip is taking.

What do I need to configure on the router to check this?

Camera [Ethernet] <--> [Ethernet0/0] Cisco Router [871]  <--> Laptop [App to capture movie clip]


I have this problem too.

You can enable Netflow on your e0/0 to analyze BW utilization on your 871. Below is a introductory document explaining how NetFlow works and some free tools to export data for analysis :

Is netflow supported on a switch?

If I have the camera connected to a switchport how can I calculate the bandwidth?

What I am trying to do here is - I have a camera  attached to one of my switchport - fa0/0/1. How can I find out how much  bandwidth it is taking for streaming video?

Yes, 871 supports netflow. Check Appendix A of the document I sent for basic configuration example. As a target you can define your laptop running free Netflow analyzers available like Solarwinds' Netflow analyzer :

I can't configure the Cisco 871W router to get the ip address.

[Wall Jack] --- [WAN interface] FastEthernet4 ---- FastEthernet0 [Camera]

If I connect a switch I automatically get the ip address assigned to my Camera.

[Wall Jack] --- Switchport Fast1/0/1 --- Camera [Switchport Fast1/0/2]

IP address assigned to the Camera, but, now I can't run netflow.

I configured a DHCP pool on the Cisco 871W router but with no luck. Any help will be appreciated.

My 871W router does not support netflow.
