2 TopicsStacked 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 tried to connect them on a regular port instead of the stack port with a single cable. (but leaving the stack configuration as is) Everything stopped working because the regular port got blocked by STP (Discarding status). I have tried to connect 1 S3300 to another dummy switch, and it's working. I'd like to know if the fact that those switch have a stack configuration, it will trigger STP to block the link between them, even if there's not actual cable on the stack port. Is that normal ?3.4KViews0likes2CommentsTrunking between 2 switch stacks (M4300-52G-PoE+ stack & M5300-52G-PoE+ stack)
I'm not a networking expert, so I wanted to toss this question out there to see if someone could point me in the right direction. I have (2) seperate network stacks in 2 seperate builtings connected by a SFP+ fiber trunk connection on ports 1/0/51 on both stacks. I'd like to connect a second SFP+ fiber/trunk connection between both stacks on port 3/0/51 to increase redundancy, but Im not sure exactly how to do it without creating a LOOP situation. I've never done any kind of LAG configuration, but everything I read tends to point me in that direction. I found a post discussing how to configure a LAG ( https://community.netgear.com/t5/Managed-Switches/sfp-trunking/m-p/1061504# )and the person posting referensed a document titled how_to_configure_lag.pdf, but that seemed to confuse me even more, since the browser GUI in that document looks nothing like the browser GUI on my M4300 and M5300. The article also mentioned needing to configure STP on each stack to prevent a LOOP, but I cant seem to find any documentation that can better educate me on how to do this. If anyone out there has any links or insight they can provide me when it comes to combining 2 SFP+ ports into a LAG and then trunking to another switch that also has 2 SFP+ ports combined into a LAG it would be greatly appreciated.
