New major firmware may also include additional performance, security and/or stability enhancements. The management VLAN, which is VLAN 1 by default, should be changed to a separate, distinct VLAN. In almost all cases these are simply a matter of seconds as spoke sites fail between concentrator pairs, but the impact can become more noticeable if there are WAN connectivity problems between the data center and spoke locations. The configuration is complete and the stack should be up and running. In this advanced technical training course, you’ll learn how to plan for network deployments and integrations using the Cisco Meraki platform. Re: How to schedule downtime - best practices I should have been clearer in my request. When you move farther up the networking stack to switching there are additional things you need to take into consideration. If switch count exceeds 400 switches, it is likely to slow down the loading of the network topology/ switch ports page or result in display of inconsistent output. This was done by moving the selected APs into their own dashboard network so they could be assigned a (beta) firmware version, separate from the main network(s). Upon completion of these processes the firmware can be promoted to "Stable." The upgrade process for a stack follows the same high-level process outlined previously, with each stack member rebooting close to the same time and the stack then automatically re-forming as the members come online. Is there any information about: ISE, MS Intune Each product line has automated and manual testing specific to the product, that are designed to ensure Meraki minimizes the chance of regressions as we continue to create and expand on our software feature set. Every firmware version is created and released with the goal of graduating to stable. Your existing template will not be split, so it will have an environmental option. We recommend selecting a time that is most convenient to your business needs, and if you want to, you can set this time as your default upgrade window under your general network settings. The firmware version is named using the format given below: .. Each queue is serviced using FIFO. Given the central/upstream nature of MX devices, it is also recommended to allow for sufficient time to monitor and test after the upgrade completes to ensure the maintenance window completes successfully. IoT Smart Cameras Protect your people and assets with intuitive video and analytics. For example, if the sender is in VLAN 100 (192.168.100.0/24), the sender's IP address can be 192.168.100.10 but should not be 192.168.200.10. VLAN 1 should be allowed on a trunk between Catalyst and MS. As with all of our cloud features, we are continuing to build more functionality in the firmware upgrade tool to increase usability and simplify firmware management. This is useful to optimize server-to-server and application performance. during daily operation. When concentrators are configured in HA, they will follow the steps mentioned above. Channel Planning Best Practices WPA3 Encryption and Configuration Guide Signal-to-Noise Ratio (SNR) and Wireless Signal Strength Meraki MR SU-MIMO, MU-MIMO, and Beamforming Recently added (date created) Wi-Fi 6 As part of our upgrade toolset, we automatically handle the upgrade of the entire switch stack. Configure cross-stack link aggregation for uplink connectivity. The switches may reboot during this process. VPN tunnels will begin establishing to the spare appliance while the primary is upgrading. The high-level process for a switch upgrade involves the following: The switch downloads the new firmware (time varies depending on your connection), The switch starts a countdown of 20 minutes to allow any other switches downstream to finish their download, The switch reboots with its new firmware (about a minute), Network protocols reconverge (varies depending on configuration). This approach allows you to test new features and verify stability in your production environment before rolling out new features globally. The purpose of this design guide is to provide guidance and best practices for deploying voice-over-IP (VoIP) services in a branch-office environment using Cisco ® Meraki ® MS switches, Meraki MR access points, and Meraki Thanks to the agile and cloud-based firmware development process used by Meraki engineers, there are a few things you can do to make these deployments less risky. As a network deployment grows to span multiple sites, managing individual devices can become highly cumbersome and unnecessary. Dataflows best practices 12/10/2020 2 minutes to read d D In this article Power BI dataflows are an enterprise-focused data prep solution, enabling an ecosystem of data that's ready for consumption, reuse, and integration. Use 2 ports on each of “top” and “bottom” switches of the stack for uplink connectivity and redundancy. Second, when upgrading a wireless network, client devices with older drivers may have issues with new features. For example, if you are using L3 roaming, some different versions of firmware may not be compatible with each other for L3 roaming features in particular. A formal review of the beta firmware’s success is conducted by our software and product teams. If you follow this design, ensure that the management VLAN is also allowed on the trunks. Ensure all areas are directly attached to the backbone Area 0. Yes, there are best practices. From a security perspective, the benefits of the cloud are unparalleled. If you have any issues on the new beta firmware you can always roll back to the previous stable version, or the previously installed version if you roll back within 14 days. As our wireless portfolio grows, Meraki continues to focus on delivering the high performance and high availability network that modern deployments require. It is recommended to use 239.0.0.0/8 multicast address space for internal applications. 10 Best Practices for Designing Your Event Wi-Fi Deployment June 30, 2011 Posted by: Pablo Estrada Share LinkedIn Twitter Reddit Email Conference and event Wi-Fi is notoriously difficult to manage and run successfully. Beta firmware can be considered analogous to “Early Deployment” firmware seen in other products in the industry. In the scenario where you find the new beta or release candidate firmware is functioning as required and you would like to use this version on your entire deployment, go ahead and deploy this version across your entire deployment - we strive to deliver high quality firmware at all stages of our development process. All other traffic would receive 1/13 or ~8% of the bandwidth. Make sure that all Multicast Routing enabled switches can ping the RP address from all L3 interfaces that have Multicast Routing enabled. In this case, we started with the access layer switches in Stage 1 and gradually upgraded toward the core in Stage 3. A Cisco Meraki MX security appliance operating in NAT mode is best deployed when its WAN connection is directly connected to the ISP handoff An MX can operate in NAT mode if it is behind another Layer 3 device that is also performing NAT, but you may run into complications with Meraki cloud connectivity, as well as some features such as Meraki Auto VPN On a high level, traffic can be classified based on VLAN (user, voip, network control etc). To help alleviate these operating costs, the Meraki MS switch offers the use of templates to quickly roll out new site deployments and make changes in bulk. These upgrades can be canceled, modified, and reverted using the firmware upgrades tool in the dashboard. A querier or PIM enabled switch/router is required for every VLAN that carries multicast traffic. Instead, a dedicated transit VLAN can be defined and allowed on trunks, typically between the core and aggregation layers with OSPF enabled and “Passive” set to “no.” For all other subnets that need to be advertised, enable OSPF and set “Passive” to “Yes.” This will reduce unnecessary load on the CPU. Solved: Hi team, I am trying to figure out if we can initiate a port bounce to a Meraki MS from the ISE Live Sessions logs. Without QoS enabled, all traffic is serviced in queue 0 (default class) using a FIFO model. Meraki differentiates itself through its firmware delivery using the Meraki cloud platform, by providing an exceptionally swift and reliable way to deliver firmware upgrades. We recommend making such changes only during scheduled downtime/maintenance window. Note that, while warm spare is a method to ensure reliability and high availability, generally, we recommend using switch stacking for layer 3 switches, rather than warm spare, for better redundancy and faster failover. After the formal review, a beta may be reclassified as a "Stable Release Candidate." If any issues are discovered that need to be resolved, we will start the process over once the issue has been addressed before moving the release forward. Now that we understand how the Meraki firmware system works, let's talk about how you can leverage this to confidently manage firmware on your network. Just FYI I ran numbers for Meraki MX/MS versus Cisco ASA/Catalyst just last quarter and the numbers came out in Meraki's favor. Customers leveraging configuration templates may also enjoy the benefits of the firmware upgrade tool. When you are scheduling your upgrades you can easily (as in the example below) mark multiple stages of upgrades. If a particular build fails to pass our key metrics at any stage of the development process, a new build is created and the process begins anew. Ensure that the source IP address of the multicast sender is assigned an IP in the correct subnet. The power LEDs on the front of each switch will blink during this process. As Meraki has grown alongside its customer base, we have incorporated tighter controls over firmware for customers who desire these while still maintaining the simplicity of cloud-based delivery. As part of our core philosophy, after a new build has successfully passed the testing phase, we deploy the new firmware release on our own personal and engineering networks. Once a firmware is marked as stable, customers can roll out firmware to all the remaining networks either using the firmware upgrades tool or, optionally, using the automatic upgrade process to roll out firmware. Cabling Best Practices for Multi-Gigabit operations, Keep the STP diameter under 7 hops, such that packets should not ever have to travel across more than 7 switches to travel from one point of the network to the other, BPDU Guard should be enabled on all end-user/server access ports to avoid rogue switch introduction in network, Loop Guard should be enabled on trunk ports that are connecting switches, Root Guard should be enabled on ports connecting to switches outside of administrative control, This should be enabled on fiber trunks - in “Alert Only” mode, This should be set to auto-negotiate for ports connecting Meraki devices, Use “forced” mode only if a device connected to the port does not support auto-negotiation. 3. Power on all the switches, then wait several minutes for them to download the latest firmware and updates from the dashboard. Unlike many other products offered by Meraki, MX appliances and Z-Series devices have a one-dashboard-network per-site model. Course overview Engineering Cisco Meraki Solutions Part 2 (ECMS2) v2.0 What you’ll learn in this course The course, Engineering Cisco Meraki Solutions Part 2 (ECMS2) v2.0 elevates your knowledge of Cisco® Meraki technology suite. When MX appliances configured to operate in High Availability (HA) (either in NAT/routed mode or when operating as one-armed VPN concentrators), the dashboard will automatically take steps to minimize downtime when upgrades are performed to ensure a zero-downtime MX upgrade. In some more rare cases, we will move forward with a build with a known regression, due to complexity or timing of the fix, and in this scenario we will note the regression in the release notes for that version. Older betas are supported with best effort; an upgrade to the latest beta will ensure full support. Please note that any problems that are encountered while running versions of firmware that are not either stable or release candidate will not be supported and Meraki Support may need to recommend upgrading to the latest version of firmware in order to continue troubleshooting. If you have a policy to only use stable firmware in production, then you can move onto the next step in the process, which is to roll out the RC firmware to designated RC networks. The following steps explain how to prepare a group of switches for physical stacking, how to stack them together, and how to configure the stack in the dashboard: Add the switches into a dashboard network. Meraki was built on the promise of making management of devices intuitive, and this extends to Meraki firmware management. In bridge mode, the Meraki APs act as bridges, allowing wireless clients to obtain their IP addresses from an upstream DHCP server. Cisco Meraki ワイヤレス システムには、同一ネットワーク内で隣接する AP のチャネル設定と電力レベルを自動的に調整する 2 つの機能（自動チャネル選択機能と節電機能）が用意されています。これらを利用することで、強力なワイヤレス Configure MD5 authentication for added security. We use the Meraki SM web-based console for app management, operations work, and Tier-3 support. It is recommended to place the RP as close to the multicast source as possible. The enterprise application would be guaranteed 4/13 or ~30% bandwidth.The switch would forward 4 frames from the CoS queue 2 and move to the default queue. Where feasible, connect the multicast source directly to the RP switch to avoid PIM’s source registration traffic which can be CPU intensive. A stable release candidate matures into a stable version over time as it is slowly rolled out to devices globally. As such, momentary service disruption may occur. For example, switch<->switch links can be assigned “trunk”, switch<->AP can be “wireless” etc, Only LACP is supported for link aggregation. Disable IGMP Snooping if there are no layer 2 multicast requirements. Customers can also manually upgrade their networks at any time to beta firmware by using the firmware upgrade tool.
