Jonathan, I am switching over from our 10mb to 100mb qmoe starting with
my signoff next week. They are (Qwest) still trying to get the circuit
to verify at 100Mb. It currently to them shows 82. How can I can test
this with just a pc on my end? I went to qwest.speedtest.net and it
isn't anywhere near even the 82 they report. How do I the customer
validate the speed I am paying for?

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.
