How many Cat 5 inputs are there in the Summit48 switch? I think one is plugged into the front but it's not working right now.

I think summit48 has 48 10/100 ports? and 2 gig-e ports.

Where are you suppose to plug the Cat 5 cable into? The front or the back? The connection provider says it's complete but I can't ping my switch.

Front.

Heres some images that I made. Which port are you supose to plug it into?

They'res 48, I guess you can just pick one and plug the cable into it.

you may need to set the port that you're upstream is plugged into as an uplink port.

There are a couple of things that could be wrong (and yes a Summit48 has 48 10/100 CAT 5 ports and possibly 2 Fibre Ports).

If your provider is connecting a switch/router to your switch, they will need to use a cross over cable as I don't think the Summits have auto MDIX. Are you getting a link light? Have you configured the switch?

They told me that they used a crossover cable and they see all green lights. Which port should the providers connection go into? Theres 4 Gigabit ethernet ports. Top left Top right Bottem Left Bottom right.

You may not be able to ping the switch. If your provider is using the Summit as strictly a layer two device, they may not have assigned it an IP Address.

Or are you talking about a switch in your rack? If so, the same thing applies.

Which port should the providers connection go into? Theres 4 Gigabit ethernet ports. Top left Top right Bottem Left Bottom right.It does not matter (or should not). Have you configured the switch yet?

Are you running a Gigabit connection to your provider?

I had the server preconfigured before it was sent out. Are there any other ways to configure it besides using a labtop?

Okay...I am a little confused :). Let me make sure I understand your set up properly, so we are all on the same page. It sounds like you are doing the following:



[Cogent Switch]----[Your Switch]----[Your Servers]
(Summit 48)


Is that right?

Yup, your right.

Can you reach your server? Are you using the Summit for Layer 3 or 2 switching? Are you using the GIG ports, can you give us more details?

I am not the one that setup the switch. I am not sure if it's set to Layer 2 or 3. I think the Gig ports are being used.

You know anyone in Santa Clara that can set this up? I can pay setup fee.

Mike -- if you don't stop stalking me on these boards, I am going to have to have a restraining order issued against you (you must stay at least 50 posts away from allan) :D :D :D.

Seriously, did the data center engineers say that they see green link lights on the ports on both switches, and are you using cat5 or fiber?

Are you sure? I don't think they would run a gig connection for a 100 Meg hand-off? Find out the answer to that definitively. If it is a 100 Meg hand-off my best guess would be a duplex mis-match. I think Cogent runs off Cisco equipment, so it is very possible that there is a communication error between the two pieces of equipment.

He said there were green lights but I don't know where. Would you be kind enough to call TIM 408-346-0213 and say you want to help with the Summit 48 switch.


Not with configuration of the software but you can ask him what he sees and what lights are on etc....

Everybody has been talking about Cogent but no feedback from a person with a Cogent connection. I will be glad to give feedback as soon as I get everything working.

Okay -- I talked to Tim. The setup is something like this:


[Cogent]---[Media Room]---[Summit48]--[Servers]


They are running a Cat5 Ethernet connection from Cogent to your switch. They run a cross-over connection from port 28 on your switch to a patch panel in the media room, which then runs to the Cogent connection.

They have light on the Cogent switch, but no light on port 28 of your switch. Tim tested the cables, and they appear to be fine. My best guess is the problem is, as I said before, a duplex mismatch your Summit switch and the equipment on the Cogent side.

I am not familiar enough with Extreme equipment to troubleshoot over the phone, so here is my suggestion:

If you have a guy/gal in the area who can configure the extreme switch send them out and check the port speed on port 28. Try to set it to 100 auto to start, if that does not work, try 100 full and 100 half (Tim was not sure what port speed Cogent set their equipment to).

If that does not work, arrange for a conference call between Cogent and your person in the data center to see if Cogent can check the settings on their end, and see if they are seeing any traffic from your port.

Hope this is enough to get you started.

A duplex mismatch would not cause the port not to light up.

Is this a used switch? if it is make sure the ports been enabled, if its new all the ports come enabled by default. Im not even going to go into routing with you if you dont ahve a light.

So step 1 is to get a light for your uplink port, if the port is enabled, and theres no light but theres a light on the cogent switch then the problem lies between the patch pannel and your switch. Which would mean the problem does not lie with you but who every set up the ethernet uplink to the patch panel.
You might have them run a cross connect direct from your switch to the cogent switch bypassing the patch panel and see if that does the trick.

Sounds like more a problem that is not the result of your switch.

By the way if you dont know what kind of a connection you have to cogent you DO NOT have a gige connection, youd have to pay around 30,000.00 for a gige connection and cogent doesnt run gige connections for 100mbps uplinks. In addition the summitt 48 does not come default with the nec. hardware to use gige out of the box you have to buy something else. Long story short you have a 10/100 mbps uplink... just a fyi...

Cogent can run GigE over fiber to their switch if they like. In fact, that's basically their business model. We have Yipes! in our datacenter for just a few Mbps (part of a local Internet exchange), and they definitely ran two GigE loops to their switch. It's just like the telco running an OC-48 cabinet even though you only need a few circuits from it.

Right, but that is to your data center. I don't think you would run a gig connection from the Cogent/Yipes! switch, to a network device in the data center that was only pushing 100 Megs. Aside from the obvious reason that Gig ports are simply too expensive to make this practical. Attempting to rate shape a Gig connection down to a 100 Megs does not work very well.

No argument there. It does seem like they're just talking about a 100Mbps Cat5 handoff. Apparently no one involved has a phone handy, but they can get to this Web site ;)

I called Tim in the DC for Cluster and verified that it is a Cat5 connection running to a 10/100 port, but I can't help configure an Extremee switch remotely (once I get into them I know my way around...I guess it is like not knowing the lyrics to a song unless it is playing).

Whatever happens let us know how it goes Cluster :)!

I just had a talk with the guy that configured my switch and he said all ports are open

Its a problem then between your switch and the patch panel, which means what ever DC your in needs to fix it....

Im suprised the DC wouldnt already know this...

And what i said about gige was exactly right, i never said cogent didnt run gige to their switch if you read my original post youll see i clearly said that the uplink to the end user is def. not gige.

Hmmm, they told me they tested all the lines and they were fine. Cogent told me full duplex and auto negotiation off have to be set.

Okay, is port 28 on your switch set to 100 full, or have you not been able to verify that yet?

One sec and I will get you the command to verify that setting.

I have not verifyed it yet =(

you def have to have the port setting set up correct or youll lose tons of packets, but again ive never seen where it would keep a connection light from appearing on your switch. Of course i dont have direct exp. with cogent, but the negotiation of speed and duplex does not inhibit a port connection or even data flow. Hence I dont think setting your port right will make a difference if theres no connection light.

As far as setting up your switch are you using command line interface if so youll find it much easier to use the web based interface, of course that wont work i guess if you cant set up a ip.

One more fyi, the ports on your switch if its a factory switch will be auto set to auto negotiate IE the port will determine which duplex to use and at what speed to run at. Most of the time exp. on an uplink connection the port should manually be set because it doesnt auto detect your uplink ports setting correctly. But again, this wouldnt in my opinion cause your link light not to come on, changing your port settings all day wouldnt fix a connection problem.

This should be the command to set port 28 to 100 full:

config port 28 auto off speed 100 duplex full

try that and see if it helps.

If you don't have link light, there most likely is a hardware issue either with the cables, patch panel, etc. Link light has nothing to do with the duplex/speed settings but is the actual physical link on the wire.

I would suggest that you triple check all the patch panels and cables. One thought might be to try a straight through cable instead of a cross over and see if that helps.

Also, with Extreme and Cisco if you have the Extreme set to auto and the Cisco set to a specific speed it will still work but will drop a few packets.

My 3 cents :)

Really? It is my understanding that there are all sorts of negotiation issues between Extreme and Cisco, and that it is better to hard code the speeds.

It is better to hard code (unless you are running some HP switches & Cisco switches) the speed/duplex, you will get better results. But if you don't it will still work, but you will really see degration on anything about 1 Mbps.

They told me they are using patch cable. I don't think thats the same as cross over cable.

A patch cable can be straight or crossed.

That just means they are running the caple to a patch panel. You can use both strait through and crossover cables.

I am sure your host has set this up before (I assume they have multiple customers running to the same patch panel), so they should know what type of cable to use.

Have them recheck the cable to make sure it is working properly, and, as Mike suggested have them switch to either a strait through or crossover cable (whichever one they are not currently using).

I can't wait any longer. I will just buy the right type of cable and ship it over. I will buy more so I can use them in the future. Is this the right kind? Cable is cheap anyways

Belkin is the best?

Id be slightly worried if your provider cant trouble shoot a bad cable. Are you going to bypass the patch panel with this cable or are you buyiong a cable to go from your switch to the patch panel.

They connected the cable from the Cogent switch to my switch and the light still didn't go on. I am going to use all cross over cable. Even use cross over cable from switch to servers so I hope it fixes it.

Even use cross over cable from switch to servers so I hope it fixes it.Well, that's not going to work. The only time you should need to use crossover cables is when you are connecting two switchs/router or two computers together. Like devices usually need a crossover.

Did you get it fixed?

Switch to switch you should have a cross over cable.

Side A: w/o - o/w - w/g - b/w - w/b - g/w - w/br - br/w

Side B: w/g - g/w - w/o - b/w - w/b - o/w - w/br - br/w

(this is the cable facing you with the tab down on both ends)

Cisco and Extreme work very well in auto negotiate. I have used them for many years.
