Didn’t realize this was out there now. This looks totally sane and awesome, and what would be expected. Only suggestion would be to make the storm control limits consistent (i.e.: Juniper == 10% of 1g port right now, Cisco = 20%) Would be interested to see if same (or similar) config is on the main MICE switch ports facing the leaf switches. Per the discussion at the last member meeting about how the treat the leaf switches (as a member connection), would seem appropriate to have these limits there too (and hope that similar config is in place downstream on member run leaf switches too). -- Andrew Hoyos hoyosa(a)gmail.com

The config is listed here: http://micemn.net/technical.html Specifically: set ethernet-switching-options storm-control interface X/X/X bandwidth 100000 - and on Cisco - storm-control broadcast level 20.00 I can't say personally whether that's actually applied, but I believe that's been completed. Maybe it wasn't applied to the ports facing remote switches. Can anyone with access to the switches comment on that? I'm not sure off the top of my head what level of traffic these numbers represent. -- Richard

I agree. We all need to make efforts to improve the stability of the exchange. This is causing Atomic issues with reliability and we are considering bypassing the exchange for our critical traffic. ________________________________ From: MICE Discuss <MICE-DISCUSS(a)LISTS.IPHOUSE.NET> on behalf of Andrew Hoyos <hoyosa(a)GMAIL.COM> Sent: Friday, January 30, 2015 4:24 PM To: MICE-DISCUSS(a)LISTS.IPHOUSE.NET Subject: Re: [MICE-DISCUSS] Packet loss across the exchange I thought some sort of loop detection / storm control was configured recently?

Re: Packet loss across the exchange

Something is still wrong with the exchange. I wonder if the loop tripped off the forwarding issue. There is no reason for there to be hundreds of megs of traffic hitting the route servers From: MICE Discuss [mailto:MICE-DISCUSS@LISTS.IPHOUSE.NET] On Behalf Of Levi Pederson Sent: Friday, January 30, 2015 4:18 PM To: MICE-DISCUSS(a)LISTS.IPHOUSE.NET Subject: Re: [MICE-DISCUSS] Packet loss across the exchange All, We're shifting some traffic onto our 10Gig link, and accidentally created an L2 Loop within the Exchange.

I thought some sort of loop detection / storm control was configured recently? Do we need to revisit that? Seems like shutting down a port (even if a leaf node) at 10% broadcast limit would be better than effecting the whole exchange.
