Aug 5, 2021 · Over the years I know the Meraki design preference has shifted away from direct link between each Meraki for VRRP, but I'm seeing issues since the MX's do not participate in spanning tree. I particularly like Option 6: Two MX, two ISPs (4), which ensures that there is a backup for each component (FAI, Switch and MX). Upgrade Steps for Cloud-managed Catalyst Switches. If they are dumb layer 2 switches it is possible they don't even run spanning tree. The Meraki logs show the port transitioning to Root much faster than the time it takes for it to start passing traffic. I am not blocking VLAN1 anywhere. 3 Kudos Subscribe. its just the BPDU for instance 0, the CIST). Sep 19, 2019 · Curious what the consensus is on STP guard settings for ports on Meraki switches. spanning-tree portfast edge end. There is no need to run 1000 instances. This will make the entire design loop free. The links between building C and A should be put into a port channel. Ethan6123 (Ethan6123) February 9, 2021, 3:23pm 6. Mar 12, 2021 · Meraki switches do running Spanning Tree Protocol (rapid spanning-tree to be precise), but other than the priority of switches there is nothing more that you can configure. Mar 28, 2022 · Hello, I have a question for those who have worked with configuration templates. Issue: Meraki switch is CST root, and adjacent to MST cloud. Jan 6, 2025 · Make sure Spanning-Tree Protocol (STP) is enabled on the downstream switching infrastructure, as a properly-configured HA topology will introduce a loop on the network. I would expect it to be much faster. If STP is enabled, the switch would participate in the Spanning Tree process, if STP is disabled, the switch would not participate in any STP processing, including handling BPDUs. (CS16/17 to Cloud Native IOS XE) via Meraki Dashboard. LAN Redundancy features. The downstream ports from basement to the other switches should be configured as trunks and as a best practice you should enable root guard to prevent some other downstream switch from claiming root and changing your STP topology. How can I prevent STP topology change issues when deploying new APs. Spanning-Tree Protocol (STP) behaves differently in cloud-native IOS XE 17. configure terminal. Determine the best switch to be Root switch and set Bridge Priority (spanning-tree vlan x priority 0) 3. How can I get rid of it permanently. Meraki meraki is obviously not a catalyst and you have to design with the functions it support. Sep 4, 2020 · While RSTP is enabled on a switch port, that port is able to participate in Spanning Tree processes. That setting is no longer available via the network settings when using config Feb 14, 2022 · Spanning Tree is going to be your enemy here unless you make sure your Non Meraki switches are set up to play nice in such an environment. Meraki switches do not run Feb 24, 2024 · I decide to setup a dual uplink for redundancy purposes and so I went ahead and configured 2 aggregate port on the Meraki (port26 on switch27 and port 49 on switch 29) and FS end. I also need HA for the network ,please advise how the diagram and the setup would be like. interruption that looks like it's caused by some Feb 27, 2024 · I'm not sure but If a Meraki switch receives a BPDU on a tagged VLAN from another switch running PVST, it would handle it based on its STP settings. - We use loop-guard on switches with multiple uplink-ports to prevent loops in case of spanning-tree or Jan 10, 2019 · The RSTP BPDU is fundamentally the MSTP BPDU but without the instance information (i. Jul 11, 2022 · Following this the spanning-tree etherchannel guard misconfig will fire and will put your ports into err-disable until your err-disable recovery kicks in and re-enables the ports and the cycle continues after receiving new BPDU's However Cisco switches by default run PVST+ or RPVST and these use 01:00:0c:cc:cc:cd. P2P connection between (Meraki) CST root and MST switch root is STP flapping because superior BDPU conflict. 577982192 MS220_8P events Port 5 received an STP BPDU from 78:FE:3D:90:7F:43 so the port was blocked: events: spanning-tree interface role change: 1379970476. 1D) and RSTP (802. 1. Spanning tree shuts down STP ports that are in a Port Fast-operational state if any BPDU is received on those ports. Here to help Jan 5 2024 5:18 Apr 1, 2022 · At the global level, you enable BPDU guard on Port Fast-enabled STP ports by using the spanning-tree portfast bpduguard default global configuration command. Feb 28, 2024 · I'm not sure but If a Meraki switch receives a BPDU on a tagged VLAN from another switch running PVST, it would handle it based on its STP settings. 1D) is predominantly used to prevent layer 2 loops and broadcast storms and is also used for network redundancy. Go to Switch -> Switch Settings, then under STP configuration, click the ‘Set the bridge priority for another switch or stack’ link, find your core stack and the set the priority low to make it the most likely root. If you found this post helpful, please give it Kudos. Feb 24, 2019 · If they are Cisco Enterprise switches I would configure them to use mst "spanning-tree mode mst". I've been having an issue getting this new MS250-48 meraki switch workingI'm wondering if I High rates of STP topology changes usually indicates an instability or changes in your L2 network. Indicates the Spanning-Tree Protocol (STP) state of the port has changed, lists the relevant port number, previous, and new states. But all the time it is required to shutdown and again no shutdown of switchport. With the 3rd Cisco in place of the Meraki, the transition is not even noticeable Mar 28, 2022 · Spanning-Tree Broadcast Storm from Connecting APs Hi all, I have a question regarding MR. In a valid configuration, Port Fast-enabled STP ports do not receive BPDUs. Meraki switch #1 is physically set up. end Jan 25, 2023 · 1. Options.

This table Jul 22, 2019 · If the root of your network is a Cisco device running RPVST, and the Meraki devices are at the edge of the spanning-tree then there is a fair chance you'll get it working Oct 27, 2023 · The Cisco Meraki MS series switch is compatible with industry standard STP (IEEE 802. In response to natuan. Also 10. ) and the edge the biggest (40960+). Jul 25, 2022 · I know I can set spanning-tree priority per switch by navigating to "Switch > Switch settings > STP configuration > Set the bridge priority for another switch or stack" in the dashboard, but I don't want to set anything, I just want to view and document current STP priority on each of the MS switches in our environment. Meraki Community Particularly corrupted spanning tree packets or unexpected spanning tree packets. It is Nov 2, 2018 · - We use bpdu-guard for client ports to prevent spanning-tree problems f. . Mar 8, 2019 · Yesterday at 15:10 one of our Meraki MS220 switches decided to disable all the ports connecting to MR34 wifi antennas. With the result that all antennas were powered off. As you indicate, you could get a pair of MS210-24P switches and hardware stack them, and dedicate them to being core switches. yiud hnfsiyt fmpuhpth hyddye hkcdzgo hkwlogn nxmunr mbmgcv ttqqwwy bvouz
