Cisco 9300 connected CIsco 3750G - Page 2

beconnect · ‎05-09-2025

HI

we changed a old switch CIsco 2960 to a new Cisco 9300.

Sw9300 connects to the existing Cisco 3750G via SFP Fiber.

this a test flat envirorment with only one vlan and some servers .

Everything was working prior to this change.

Now On the CIsco 9300 log, i see the tengigabit port flapping sometimes.

today only arises a flap up an down at 4 pm and goes for 4 seconds.

I had ping a server for more than 2 hours without any ping loss.

Could it be any mismatch between old and new switch?

If it was a problem on STP protocol we should see more events of port disabling.

Thanks in advanced

Hi all

just waiting for someone to send me the outputs needs, I am not at site now.

During the weekend this was the error log...

Hummm

Found out that client add another switch with same AP address on vlan 1!!

So this main one that we are seeing the tengig goe down is connected to another one that "shared the IP address with another switch.. For my point this is sufficcient to have cuts of 3 seconds on fiber....

Hope this is the issue

Hi

Seems that that was not the issue.

Still facing errors on uplink and this is the weekend , so less or none users.
