VLAN ON A SWITCH SHUTDOWN AFTER A SWITCH IS CONNECTED TO THE NETWORK.

Thank you for the july 9 response. Today, I updated cisco 3750-24 firmware to c3750-ipbasek9-mz.122-44.SE2 after configuring the ip and the vlan X. I then disconnected the switch and using the console port, changed the IP number,set the vlan to a different vlan X2. I then shut the old vlan X and removed from the configuration, by "no vlan X. I then took the switch and connected to the new vlan X2, but as soon has it came up, the switch controling the old vlan X was shutdown. That switch was then restarted and the "no shut" was issued on that vlan X. Is there a known bug that could be causing this?

Your help will be appreciated.

Re: VLAN ON A SWITCH SHUTDOWN AFTER A SWITCH IS CONNECTED TO THE

Hi,

Iam not sure about the July 9 Query. Are you talking about 'inter Vlan' going down, when the other comes..? If that is the case, it is because of the image you are running. You need 'IPSERVICES' image rather than base image. It will let you have multiple 'int Vla' up and running at same time (pure Layer3). Apologies..incase if I get your query wrong.

Thank you

Re: VLAN ON A SWITCH SHUTDOWN AFTER A SWITCH IS CONNECTED TO THE

here is the text of July 9 that I posted:

"I have a 3750g-48 switch with static IP and 12.2.35 se2 ipservicek9 ios working fine. By mistake I connected another 3750g with the same IP address but with 12.2.44 se2 ios. they both have the same vlan. I shutdown the vlan on the new switch and the old switch went down. My question is that did the old one go down because I shutdown the vlan or because of IP address conflict?"

thank you.
