Stacked S3300 not communicating through regular port
Hello, I have 2 stacked S3300 that have the default configuration except for the stack configuration, i'm using a 10G link port 49. Everything was working great. I need to make some change and I...
Hi,
When the two switches are stacked and connected via the stacking link, then a loop will occur if you try to connect a second cable on the "normal" ports. It is like connecting two end of the same cable to the same switch. STP will shut that down.
However, if you break the stack apart (remove the stacking link) and then connect the switches via a normal Ethernet connection, well then STP should not shut that down. Question is whether you connected the Ethernet connection before you removed the stacking cable?
What sort of configuration caused you to want to break the stack? All configurations should normally be done on the running stack. Another thing you might not have taken into account is that when you break a stack, both units have the same IP. So, if you subsequently connect them via normal Ethernet, there will be IP conflicts, etc.
Cheers
I removed the stack cable prior to connect the ethernet cable.
I intend to use the stack again, but I've notice during the inital setup that when connecting switches stack cable, it will initiate the election but during a minute or two I'll lose the network. Since we have a high availability environment, I wanted to test the new link (which is a LANX) on regular ethernet before attempting a nightshift and re-stack.
You're right, I didn't thought about the same IP conflict, that would maybe explain why.
