Site B has switch 10.31.1.11 and server 10.31.4.38

I am confused now, can you draw it out?

Also, still no answer as to type of fiber and what is the distance? And the switch event logs?

I have the distinct pleasure of having some old single mode fiber that does not support GB connections and it is PAINFULLY slow or does not work (depending on length) if you try it. And even if it is Multi-mode, what spec is it and what is the distance?

Fiber is new. Single mode. Working on a diagram but I am having some trouble. I will post when I get it done.

Also, what are the models of the Switchs/ router This may help us out a lot.

Check with your vendor on your Single Mode fiber as I have not seen one yet that supports GB. You will need to degrade your switch connections down to 100MB.

That is why Multi-mode costs more.

Hey Chuck, running 1gb over single mode fiber would show up in the ping, wouldn't it?

Core is a HP 9300. Site A and B are HP 2848.

* Four 10/100/1000 ports or mini-GBIC slots for optional fiber connectivity such as Gigabit-SX, -LX, or -LH

Now the question would be is is Single Mode or Multi?
And get that diagram for me :)

Single mode from Site A to core (about 2 miles or so). Multimode from Core to Site B (located in same Room).

Increasing the cache size of the ping using the /l switch would provide some meaningful information. A 32byte default ping size is not that big.

I just did some updating of my Fiber Optics knowledge. It looks like the newer Single Mode fibers are the way to go.

Did. Back at you.

Hey, JKF, I am out of here in 15 but will be back on Sunday PM or Monday AM. Good luck buddy and look forward to your updates. This is a good one. :confused: ;)

JKF,
How are you coming along on your diagram?
Do you have Visio?

Having trouble getting it sized correctly to post.

I have attached a .zip file that should have a jpg image of what I am trying to explain.

Do you have a link or something to the zip?

Attached .pdf. Did not look like the zip file went.

I see a backup connection to the Internet. How is that connected. Do you have two ISP connections? Do you have two routers? Is this a single ISP and router with a connection to each switch?

If this is the same ISP and router, then do you have Spanning Tree Protocol enabled on your switches? Did you assign a cost metric to each leg with the backup connection receiving the higher cost metric?

Have you logged on to your switches and looked at the event logs? Be sure and go to the last page for the latest information. Any STP errors?

No backup connection to ISP. It is backup to our core switch. Normally Wireless connection is left powered down and olny used (powered up) if the fiber connection goes down. So we did not set up spanning tree. From our core we link to firewall and then ISP. Event logs on switches don't show any errors, collisions, nothing that looks out of the norm. No high packet counts on any specific ports.
