Re: [j-nsp] How useful is Juniper storm control?
Date: Tue, 14 May 2013 14:29:35 + From: James S. Smith jsm...@windmobile.ca Subject: [j-nsp] How useful is Juniper storm control? I'm looking for people's experience with storm control on Juniper switches. We have a pair of EX4500 switches and I notice that storm control kicks in a lot. I'm concerned that it might be stopping legitimate broadcast and multicast traffic. Depends on what you consider legitimate, both quality and quantity wise. MS Windows NLB (Network Load Balancing) floods stuff, so I have ~250Mbps minimum of flooded traffic on that VLAN... We disabled storm control on the ports in that specific VLAN, and yes, we really will do normal loadbalancing if I can get the Exchange admins to budge... Do most people have storm control enabled or disabled? Enabled, it can prevent other bad stuff, like looped traffic, not per se a loop on the specific switch. Plus, it's a switch, not a hub. :) Kind regards, JP Velders ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp

[j-nsp] How useful is Juniper storm control?
I'm looking for people's experience with storm control on Juniper switches. We have a pair of EX4500 switches and I notice that storm control kicks in a lot. I'm concerned that it might be stopping legitimate broadcast and multicast traffic. Before we put in these Juniper switches into the network we had some Cisco 3750 switches and everything was fine. In both cases we run spanning tree, so there are no loops in the network. The only experience I've had with broadcast storms forming is in a layer 2 network without spanning tree. So is storm control useful in a spanning tree environment, or is it unnecessary? Do most people have storm control enabled or disabled?
