Cisco 3825 (Qos? Many Public IPs)

techdemon

Level 1

We will shortly be installing a Cisco 3825 router, to be connected to the BTNet service, over fibre.

We will be binding many public IP addresses to the router.

Is there a way of defining a specific bandwidth limit per IP address, or range?

Many thanks

Hi,

You could implement class-based policing.

Thank you. You can specify IP addresses using this method?

If, and I believe this to be the case, we are not given full access to the router (managed service), is there a recommended hardware alternative we could use to define bandwidth/speed limits per IP?

Hi,

you can match an ACL to define the class so you could match on IP addresses but then you'll end up with a lot of classes, it should be better to match on ranges imho.

Concerning another device I really don't know, other people here will surely answer this request.

Regards.

Alain.

Yes (as also answered by Alain)

You could use another router "in front" of the managed router, or a special 3rd party bandwidth management device, but less expensive solutions might include having the managed router provide this or don't use the managed router at all.

Thanks everyone.

I've checked and it seems we won't be able to access the router

So I guess we need to look at getting another bit of kit there to manage this. Any suggestions ?
