cisco sg200-50P partial outage
Hey everyone,
Sorry to bother over a weekend but couldn't be helped.
Last evening, Friday, I sheduled to reboot all my company switches.
3 on the 3rd floor which are connected to the Sonicwall 2600 and one on the 7th floor.
After the reboot, all switches came up except the 7th floor switch, meaning, while I could access the switch, none of the devices I tested could connect to the internet.
Meaning, LAN connectivity test failed, and one wifi AP was hard down which is connected to a vlan on that switch.
I have 2 vlans, XO for servers/printers/switches, XO:v107 for hard wired desktops, and XO:v108 for 4 wifi AP's.
Whats interesting is that the AP that is hard down, is sitting next to a brand new Sonicpoint AP which another admin was configuring, planning to relocate it later. It's connected to an entirely different network all together, not the problem switch.
I explained to the admin that he should relocate the AP as interference may happen, meaning, I dont know what channel it's broadcasting on. Of course that was not done and I also did not shut down that AP like I should have.
On that same floor [7], another AP [mine] on the other side of the building is working fine, and I was connecting thru it to the Internet last evening and can ping it now.
All 3rd floor devices are also fine. 2 ap's and 3 switches.
Is it possible that this new Sonicpoint AP is somehow causing interference to the extent that LAN connectivity is down, and has knocked out my AP sitting next to it? Because I see nothing at all in the logs, and I have detailed logging enabled.
Thank you in advance....

I am in the process of re-verifying the switch configs yes. I made no changes prior to reboot and I do have a backup.
There are wired devices on the 7th floor, but I could not test them all. I can ping them from the Sonicwall so I assume they are up.
I am in contact now with the other admin asking for shutdown of that AP.

Ok, made some progress. The AP on the 7th floor which was hard down was due to the switch port being TAGGED for its vlan instead of UNTAGGED, I corrected it and it's UP. Whats weird about that, is it was working all along before the reboot.
All thats left is LAN connectivity, for that I need to be on site

Once you are on site, you need to check for router / switch configurations. It is usually easy for a router to get internet and switches just pass signals through.

Everything is working as expected today after I untagged a couple devices. So ye, it was a unsaved switch setting that caused this issue. Thank you again, I'll split the points.

Both solutions assisted me in solving this issue, a unsaved switch configuration. So, ALWAYS backup the running configuration, no matter what, prior to a switch reboot.
Thanks for the update and I was happy to help
