That's interesting, and I think i have noticed that too. Sometimes we will just get a random alert saying new DHCP server detected but of course it's the same one it should already have seen. What's odd is we did an upstream router hardware replacement last night, and afterward it sent these alerts all night. No one has reported any issues, so I am assuming it may be a quirk with the Meraki system.

Sure, it's the ones generated when you check this in the Configuration Template alert settings: Looks like this: The switch in the network XYZ detected a new DHCP server with the following details: MAC: aa:bb:cc:dd:ee:ff IP: 10.80.8.50 VLAN: 60 Subnet: 172.18.254.0/24 - Cisco Meraki

Hi all, We have enabled alerts for new DHCP server detection on our MS250s. Is it normal behavior for these alerts to come in multiple times for the same server? For example, we run a couple DHCP servers that were first seen by Meraki about 2 years ago. But it seems every time we have to reboot a switch or it loses and regains cloud connectivity, it will begin sending the DHCP alerts all over again for the same servers. Just wanting to rule out any config or network problems that could cause these alerts. Thank you

Hi all, Looking for some advice here as we are looking to take a switch from a network and move into another network where we will stack it with another standalone switch. I don't see any docs pertaining explicitly to this type of migration. We have a single switch in Network A and a two-switch stack in Network B. We want to remove a switch from the stack in Network B, migrate it to Network A and create a stack with the existing switch in Network A. Could someone please give a sanity check to this plan (feel like I might be overlooking something) 1 - remove the switch B from its current stack in Dashboard (manage members) 2 - remove switch B from Dashboard network (should clear config --> maybe a complete wipe is better?) 3 - power off switch B and disconnect physical stack stables from other switch in Network B 4 - power off switch A 5 - physically connect stack cables (switch A to switch B) 6 - power both switches back on 7 - move the switch B into the Network A network via the Dashboard 8 - apply template to switch B (since it will be a different VLAN) 9 - dashboard should recognize new stack and ask if you want to provision a new stack 10 - follow prompts to set up stack in Dashboard

I ended up calling Meraki support, and if use you use a template for a network that has has an aggregate port, it won't pull the tag. you'd have to remove it from the template. otherwise, it works fine for any uplinks that aren't in a port group.

Hello everyone, Would like to set up alerts on individual ports that are part of LACP group? I know you can use tags to monitor specific ports, but I am unable to get the tags applied to the LACP group to show up on the alerts config page. I applied tags at the individual port level and the aggregate port level, but they will not pull up on the alert config page. Is there another place to apply the tag? Or is this not possible with port groups?

Thanks for the tip. I have also noticed that if the status is 'Forwarding' some have BPUDguard enabled and some do not. It does not distinguish, but only states 'Forwarding'.

I am only seeing "Enabled" or "Forwarding" under the RSTP column in the Dashboard view. Is there a way to see if BPDUguard is turned on in a similar view?

Not able to find any information anywhere, so this may not be possible, but wanted to ask here in case. Is there a type of report or API call that can be generated that show all MS250 switchports which have BPDUguard enabled?

I have a pair of existing production switches (MS250s), that we'd like to put into a stack. Unfortunately, I couldn't find any documentation specifically explaining how to do this. Is it as simple as powering down, connecting the stack cables, and then power back on and configure as a stack in the dashboard? Are there any caveats or things to be aware when trying this? TIA

Hi all, We have been noticing numerous RSTP role/status change events in the logs for several of our MS250s. Below is an example of one that occurred within a two-minute window. These event logs come in off-and-on all day on multiple switches. Odd thing is that no one seems to be reporting any issues, and we noticed this several weeks ago. So I am wondering are these some type of errant log events or a bug? Perhaps I may not understand what they mean fully, but it shows ports are being disabled many times a day. I inquired with support about this, and they suggested enabling BPDUguard on the ports, which we did, but it made no difference. If anyone has experienced something similar or if you know what may be occurring here, please let me know. TYVM. Edit: We are running firmware 15.21.1

These two stacks are in the same building, and in the same closet, but they are not connected directly. We use physical stacking cables to combine the switches into a stack. Both stacks uplink via their own LACP bundles to the same access aggregation switch. Since both stacks are on the same VLAN there is no routing between them. Any other routing is done upstream on a firewall. User connected ports are access ports. All inter-switch ports are trunks.

We don't have any small unmanaged switches in the equation, but that is very interesting.

Greetings, We are relatively new Meraki customers, and have deployed several MS250s as access switches across our various campuses this year. Everything for the most part has been great. However, in one particular building, we are noticing some odd behavior. This building is all on the same VLAN and subnet. We have two stacks here (one with 6, one with 3). It seems anytime an end user on this network moves their computer to another desk, and consequently, to a different switch, they cannot reconnect to the network. We do see them obtain a DHCP config, but they cannot ping anything other than some devices on the LAN. Oddly, they cannot even ping their gateway. The only time when this has been successful is when the user moves close by and remains on the same switch. We tested by plugging in a brand new computer to the same "problematic" switch and it worked just fine. Our hypothesis is that once a device MAC has joined a switch, it does not work when connecting to a different switch. It feels to me like MAC tables aren't updating properly. My next action will probably be rebooting the switch, but we can only do this after hours. I am a little concerned about what behavior a reboot would trigger. Has anyone experienced an issue of this nature? Or does anyone have a recommended course of action they would take in this case? TIA for any insight you could provide.
