Hello,

my device j2350 is peering with two neighbors, in one peer I want to limit my servers, for example one server 5 mbit/s, second server 2 mbit/s and so on.

What is the best way to do it?

Use firewall policer or  anything else?

Hi

What do you mean by "peering with two neighbors" ?

In which way do you wan to limit traffic (inbound or outbound) ?

If you want to limit incoming traffic (inbound) you have to use Firewall policer.

If you want to limit outgoing (outbound) traffic you would rather use shaping (under COS)

Hi,

I have two bgp peer's, and on one bgp peer I have limited bandwidth.

My aim is not to let one server to full link in this limited peer.

Actually I want to limit traffic in both ways inbound and outbound.

If your two peers are on the same interface you will only be able to do some rate-limiting via an input and output firewall filter !

If you have two different sub-interfaces you would be able to do some more intelligent limiting (shaping) in the outbound way, but I assume it's not the case !

Hi,


I use different units for every peer.
can you give me some information about - intelligent limiting (shaping)?
May be it is that what I need, if not I will learn some new thing.

You will have to do a config like that:

class-of-service {
    interfaces {
        ge-0/0/0 {
            unit 0 {
                shaping-rate 5m;
            }
            unit 1 {
                shaping-rate 2m;
            }
        }
    }
}

this config will limit outgoing trafic on interface ge-0/0/0 unit 0 to 5mbps and unit 1 to 2Mbps

Hope this will help you !

Hi,

thanks, for your help.

I think policer will be better solution in this case.
