[LARTC] How to specify bandwidth

[LARTC] How to specify bandwidth

[Jaco van der Schyff]

Greetings,

I have a quick question as how to specify bandwith on my eth0 device.

I have a cisco router connected to eth0, and the cisco router is 
connected to our ISP via a 320Kbps link.

When I specify the bandwith in tc, do I specify it as 320Kbps (the
bandwidth of the internet link) or as 100Mbps (the bandwidth
available on eth0)

And the same question as to the bandwidth on eth1 (link to lan).
Should that also be 320kbps or 100mbps?

Any help would be greatly appreciated.

Solution :
- add CBQ root qdisc with bandwidth 100mbps
- add BOUNDED class with bandwidth 100mbps, rate 320kbps
- add CBQ qdisc with bandwidth 320kbps, rate 320Kbps
- add al the other classes to second qdisc

For LAN : I suggest to do the same.
