issues with SGE2010 switch

Unanswered Question
May 5th, 2012

I am having some issues on my network and i think i have narrowed them down to a single switch.

On this switch the following logs can be seen

All other switches are ok and do not show anything in their logs

I am trying to figure out what could be going wrong. Spanning tree is enabled on all switches. The switch tihs is happening on, ends in the ip 172 and is where all building cables connect to. They also connect to 174.

I have attached an image of the infrastructure so you can visually see what i mean.

Can anyone point me in the correct direction to start solving this issue?

Thanks,

Dani

Whats the problem?

Looks like access ports going up down maybe when end devices are turned on/off.

itmanager223 Sat, 05/05/2012 - 11:04

the issue is that the network almost seizes up when this happends. On 1 specific computer you notice the network icon in windows 7 show that yellow sign and then no network connections work for a few minutes. Once the network sign goes away the network connection works again. When that happends you see these messages in the logs.

Also i am noticing high ping times on lan clients and wifi connections are extremely slow.

Wether or not the wifi issue is related i have yet to figure out.

Sounds more like a loop to me.  Does it only happen on this switch?  Or if not loop, could be errant NIC flooding network.  I have seen this recently at a site, brought down the entire site (was on Extreme Networks sw).  It was discovered when I plugged in a packet sniffer, I was seeing 700+ SSDP pps fromn this one PC.   Does a packet sniffer hooked directly up to that sw show you anything useful?

itmanager223 Sat, 05/05/2012 - 19:30

Do you mean plug literally into the problem switch and run wireshark? doesnt a switch direct packets to their intended destination and not broadcast it across all ports?

Anyways i did run wireshark on the computer i was thinking was the problem but from what i can see i dont see an issue.

I can post the logs tomorrow when i get a hold of them, i left them at work.

So maybe it could still be a loop or errant NIC. How can i view the whole network? I am thinking more or less though that i will need to individualy check each workstation...

If its an access layer switch, then put the port in the same vlan.  Doesnt always point to a smoking gun, sometimes though.  Doubt its a loop, because unless someone is contantly plugging/unplugging it ( or the switch is smart enough to err disable the port then bring it back up), a loop would disable your network w/o proper safe guards.
