We switched to Metro-E over fiber about 6 years ago, and haven't looked back, though it isn't MPLS. We just have a Point to Multi-point layer 2 network, with them breaking out switch ports at my core for each remote site. So for all intents and purposes, from my standpoint, it is a handful of point to point layer 2 connections. One thing I had to beat into my providers' head was verifying the speed and duplex of their equipment. For some, we needed 100 full, and for others, we needed 10 full. It all depended on what gear we had at each site. Even once the setting was changed, sometimes it would take an equipment reboot (theirs AND ours) in order for it to settle properly. You should not have to dumb down the connection speed to 10 mbps, as they are rate limiting on their equipment down to 5 Mbps (just like what we have). What is your terminating equipment, and are you seeing interface errors? (I know you said collisions, but what exactly are your interfaces saying?)

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.
