J-series and Cisco ME3400 L2 Issues
by Brad Fleming 12 Feb '09

12 Feb '09

Hello all! Recently, KanREN has begun purchasing Ethernet circuits from a new provider who uses a Cisco ME3400 for CPE to provide the link to us. We use primarly Juniper J-2320 and J-4350 routers for our site equipment (running JunOS 9.3 Enhanced Services). We've seen a problem getting Layer2 to function correctly with various speed and duplex settings. We tried every combo of hardcoded settings on both sides but simply couldn't resolve some L2 errors and interface resets. In the end, we found a stable setup with the J-series set to auto/auto and the ME3400 set to 100/full. Has anyone else seen similar problem using either the J-series or an ME3400? If so, did you ever find a complete resolution (or explanation)? Thanks for any insight! -- Brad Fleming Network Engineer Kansas Research and Education Network Office: 785-856-9800 x.222 Moblie: 785-865-7231 NOC: 866-984-3662

Rob, Ok. Do you want to share your experience? No point of taking this offline! Are you looking at market share, attributes and functionality on these new appliances? In this competitive world everyone has a say to the well-known Cisco and Juniper product set. What is the ASIC board type across all products? I can't see any 40Gig card support ....or any new OS features like most have available on their roadmap. http://www.geant2.net/upload/pdf/GN2-07-154v7-Deliverable_DJ4_2_2_Feasibili… .//ID and yes, looking for a job! --- On Wed, 2/11/09, Robert D.

We used DXM10 at Caltech to connect the switches at colo in downtown LA during supercomputing 2008. Configuration is pretty straight forward and box is well stable. No errors / link flaps seen on the ports. Few of the ports were LR for 7606 and some were SR for servers connecting Myricom 10GE NICs. -Azher

Hi I would like to ask your professional experience about switch throughput I have Gig Switchs eg: H P3400 /3500, cisco c4 948../ dlink In their spec, they said that it can handles Gig So far, I couldn't see their ports are used up over 200M in mrtg graph when I try to transfer 3G size files to files between computers ls there any limitation in those switchs? or I have to do configuration eg: put it full duplex instead of auto Thank you for your help

Call for data: IPv6 enabled service logfiles for analysis
by George Michaelson 11 Feb '09

11 Feb '09

Call for data: IPv6 enabled service logfile analysis APNIC is seeking operators of high-traffic webhosts, and other public facing services who can provide logfiles for their IPv6 enabled instances. Our intention is to analyse these for the distribution of IPv4, and the various sub-classes of IPv6 (native, tunnelled, Teredo, 6to4). APNIC will of course respect client privacy and sign an NDA, only abstracted data outcomes would be presented from any participant. -All participants would be acknowledged for their support in any presentations. While our preference is for access to raw logs, there may be people out there who cannot share this due to contractual or other restrictions. If you are willing to filter data according to our example Perlcode, we'd be happy to receive abstracted data if neccessary. Our tools assume the apache 'combined' log format, or things which can be simply converted to a close analogue. If anyone is interested in participating in the data collection exercise, please contract research(a)apnic.net -George
