At some point I was considering faulty hardware due to bad VVRP packets checksum. So, I have decided to use another switch to have the LAN trunk from MX connected to. Once the MXs were connected there the problem was resolved. So, I went back to original switch to see what the difference is when i noticed on the original i had stp guard - bpdu guard active on these ports! After disabling stp guard on the original switch - all went back to normal. While in the documentation recommends enabling RSTP globally, it doesn't mention not to use STP Guard for those ports as it will cause issues.

All switch uplinks are the same: vlan 1 as native + all vlan allowed. All other switches are Meraki. They are in secondary cabinets, each switch get one uplink from SW01 and another uplink from SW02. this is for redundancy if one core switch dies... the root switch is SW01 = 0 then SW02 = 8192 and all the rest with default bridge priority 32768. I have opened a case with Meraki support. At the moment they can't find anything odd with the configuration. just confirm that the VRRP packet are behaving strange. My comment (not support): A packet capture shows all VRP packets have bad checksum.

Hi Ryan, It is very simple... Each MX has only one Lan port enabled. 1st MX Lan 5 port to SW01 port 47 2nd MX Lan 5 port to SW02 port 47 SW01 Port 48 <> SW02 Port 48 Regards,

All mx and switches trunk ports have rstp enabled - YES --- is not a real link but signifies a virtual IP for LAN (there's another for WAN but as this is not a problem now i did not draw it).

Dear Forum, The two MXs are connected as in the attached network diagram (Pic. 1). However, the 2nd backup mx fails to sync = HA light constantly blinking in orange + power light is while steady. both MXs are online in dashboard. As a result, both MXs appear as Master on the dashboard. If i power off SW02 and move the 2nd lan trunk port to SW01 (Pic. 2) = it still fails. There are no ports disabled due to spanning tree. Tried rebooting all devices but it didn't help. Last time I had this issue I opened a ticket with the support. They said that the switch failed to pass VRRP traffic due to a spanning tree topology change. Checked couple of times and there are no ports blocked due spantree. Any idea what it can be? Thanks in advance! Picture 1 Picture 2

The problem is that it is installed in an environment where someone might unplug our device and connect his device and get DHCP. I'd like only for authorized devices to be able to pull dhcp.

Dear Experts, I am looking into allowing DHCP only to certain devices by their OUI to match my needs. Though my NIC OUI is FC:34:97:xx:xx:xx with the following DHCP configuration below I am still getting DHCP. There's no other DHCP server on the network, but the MX. How can I get it working? Is there a way to apply for an OUI range for example 00:00:01 to 00:00:02 Kind Regards, C.

Hi RaphaeIL, Thanks a lot for your quick response! We actually do have the Radius servers on the same premise as the clients are. When we tried at the beginning to forward all traffic from the access points directly to the radius servers on premise it didn't work. I figured out that as the access points are "reporting" everything to the Meraki Cloud it has to flow through the Meraki Cloud, and then from there back to the site (and it worked fine so far). Apparently, it can be done without Meraki Cloud as a proxy, and now I'd like to understand how to actually have ut corrected. If I change the radius servers ip addresses to point to the servers private ip addresses, then the traffic will never need to traverse through WAN to reach over back again to the local network. But then how does the access points will be able to reach the radius servers lan? Both the radius servers and the APs are on different management networks. For instance, let's say that the access points are on network 192.168.128.0/24 - VLAN X. and the radius servers are on network 10.1.1.0/24 - VLAN Y. both of the vlans are defined on the MX addressing and vlans and have gateways. Adding routing rules / group policies to allow intervlan routing? Where? How? Nowadays Private IPs in inside lan Best Regards,

Hi, We have a "special" setup for one of our sites which have its clients (PCs) connecting through the wifi using radius authentication. The radius server is physically located at the same site with the clients that try to authenticate. The traffic flow for all auth requests goes like: Client (PC) -> AP -> MX -> WWW -> Meraki Cloud -> Meraki Cloud-> MX -> Radius server We are concerned about security as some of the packets (UDP 1812) might be intercepted somewhere in between the Meraki Cloud to MX and EAP packets are not encrypted. I would like to know: 1. The radius packets sent to Meraki Cloud and back to MX are encrypted? It makes sense that all the traffic that is being sent between MX <> Meraki Cloud is encapsulated and encrypted But I don't know for sure and maybe as these are UDP1812 they are excluded from being included in the encapsulation? My question is - is this setup secure or not? 2. Is it possible not to send the packets from APs -> Meraki Cloud just for them to reach back to the inside LAN where the Radius server is?

Dear Fellowship, I would like to ask for your help achieving this with the given hardware. The goal is to allow mDNS traffic bi-directional between the two vlans 128 and 123 and in vlan 123 to only a specific server = 192.168.123.99. The network is built with MS120 switches and a MX67 router. How can i allow traffic from one vlan to another? Regards, Ale.

I used chatgpt for the same question before posting here and had a similar reply as posted by pulkit. However, after experimenting noticed that if i do not add the native vlan in allowed tagged then it will not forward traffic. that is why i have posted here my question.

Can you think of a good reason there's no an option to alert for a port going to blocking state due to a loop / spanning tree issue?

Hi, Trying to achieve the following flow: LAN Users -> get access to www through WAN1 AnyConnect clients -> get access through WAN2 And without changing the primary uplink from WAN1 to WAN2 nor doing load balancing. WAN1 is behind a firewall which is blocking IPsec protocols. There's no way to ask the provider to change that. but it is the ISP circuit with the higher bandwidth therefore the preferred one to route all lan users traffic to reach www. WAN2 has no firewall and IPsec tunnels can be established, but has less bandwidth which is not suitable using to route users through it to reach www. The only way I managed to get the AnyConnect working is when I change the primary uplink and set it as WAN2. How can I achieve this? Thanks in advance...

Hi, When working with a wired connection sometimes I see that the network adapter (windows 10) changes its name according to which network it is connected to - marked in red on the picture below. How can I create a network using the MX and broadcast a different desirable text to appear in there? My guess is by using some DHCP option but now sure which one? Best Regards, Ale.

Do I need to have both bands 2.4GHz and 5GHz enabled for WiFi 6 to work properly. Please note that my question is regarding WiFi 6 and not WiFi 6E. If i have an area which I have disabled 2.4GHz due congestion and left only with 5GHz enabled then * Would I be able to use WiFi 6 at all? * Any cons (affecting wifi6...) due of 2.4GHz is disabled? * How can I check if a client is connected using WiFi6? Thanks in advance for all helpers!

Dear forum, One of our clients manages all his connections in one place so he doesn't need different solutions for different sites. (makes sense to me) the software he is using is called Forticlient VPN. Does anyone knows if it is possible to configure Forticlient VPN in manner to connect to a client to a site that uses MX64? I have couple of users there all working well when VPN client is configured in Windows built in mechanism. However I was unable to find how to copnfigure the Forticleint VPN nor find info on the web. If it is possible at all - then main issue seems to be that I have no clue how the advanced settings should be set. - see below screenshot of advanced settings.
