Catalyst 3750 in Provisioned mode

[gagamboy15]

Hi Guys,

Recently our network has slows down, ping response to local server is high about 500~800ms, and when I logged-in to our 8x 3750 stack and issue the command below, I found this:

#Show switch

Recently, all Switch are working working and in ready state, what could be the problem on this? Also the LED on every port is blinking fast. I have also installed spanning-tree bpduguard in every port to prevent loop.

Thanks in advance.

Hi,

have you treid to remove the Switch from the stack, if no try to issue no switch * provision and after that switch * provision + reload of the stack member.

Let me know if you have more trouble with it ;-)

Hi,

We have experienced this same issue before 3 months.

Cisco 3750's in a stack...plenty of good power....been running for a long time.

We have 6 in our stack, and #1 and #4 both put themselves in provisioned mode at the same time.

I don't think the switches were really in provision mode...commands to take them in and out of that mode did not do anything.

You could just resetting just the "provisioned" switch by just reloaded the whole thing and dealt with the aftermath of doing so.

And the below link is pretty good at explaing the whole stack cenario.

Hope this will help you.

Please rate the helpfull posts.

Regards,
Naidu.

Thanks for the feedback guys.

Actually I have rebooted the switches 2 times now, last week and now. The switch are working just fine a couple years ago and I am wondering how did this happen. CPU is high and blinking LED is quite faster than normal, so I am suspecting there could be some problem with the network right now. We don't want to reload the switches every time this problem occurs :-)

thanks again.
