All WAN sites have identical hardware, identical firmware. And on most of them I'm even using the same port. I rebuilt the network a few years back and purchased new equipment for every site. My ISP sales engineer sent me a message a moment ago that this is a "simple fix" and they might have done something wrong with the VLANs on their side. I'll know shortly. The only thing I can say is at the "good" sites the ISP put in brand new hardware and also brought fiber to the sites. The other sites are using existing hardware, maybe installed a few years ago. I mentioned this to my ISP and was promptly ignored.
>>> Jonathan Link <[email protected]> 1/5/2011 3:03 PM >>> Are there any sites that have good performance, and can you identify whether the hardware at those sites is the same? I think someone else alluded to differences in hardware at your various sites could be a problem. I'd start looking in that direction.

We run Cisco VPN across all of our (non-internet) Metro-E links, just to be able to say that we know our data is secure. HIPAA anyone? Jonathan L.

Could be a misconfigured port along the way, could be bad cabling, etc… Thanks, Brian Desmond [email protected] c – 312.731.3132 From: Tom Miller [mailto:[email protected]] Sent: Wednesday, January 05, 2011 8:21 AM To: NT System Admin Issues Subject: Metro Ethernet ? Folks, I am converting our network from point to point to MVLS/Metro Ethernet. What I am noticing at some sites is that performance is worse that with the point to point circuit. Ping times greatly increased, collisions, etc. I've been working with my provider to get this resolved. First they thought it was a speed mismatch issue, so the provider's equipment and my equipment were changed to the same setting (full 100). That's not working and now we'll probably change it to full 10 (since the allocation is 5 Mbps anyway). I can also do some rate shaping on my switches, but it's a PITA and I was hoping to avoid it. Anyone else have these issues with conversion? Some sites are fine, others are not. All have same switches, model, firmware, config for trunk ports. I haven't pulled out my bag o software to look at what's on the pipe, anyone have any that would be best for this scenario? I have Praesser but I really need a site to site test/analysis tool. I just downloaded Qcheck and will see if that does it. I've also asked my provider to give me some statistics on traffic they see. Recommendations and comments welcome.
