Building a more resilient network

MS 10 Firmware is now live

We are happy to announce the availability of our MS 10 firmware update for Meraki switches. The update introduces new features that improve the overall security, efficiency, and resilience of your network.

Let’s take a moment to review several of MS 10’s most notable features!

 

Security: Multi-Auth/Multi-Host

MS 10 introduces 802.1x Multi-Auth and Multi-Host authentication options to Meraki switches.

Multi-Authentication requires each host on a shared port to authenticate individually to gain network access. This log-in process is vital for network security in deployments with many autonomous clients.

Multi-Host Authentication allows a single host to open port access for subsequent clients after a single authentication. For example, someone using a desktop with multiple VMs would only need to authenticate a single time to gain access for all of her virtual machines.  This reduces the frustration of needing to log-in multiple times when only a single authentication is needed.

 

Resilience: Enhanced Storm Control

Network storms occur when a set of switches endlessly forward packets between themselves, which clogs network bandwidth and causes normal network traffic to grind to a halt.


Enhanced Storm Control provides greater protection against network storms by allowing administrators to set limits on how much bandwidth can be allocated for certain types of traffic. If a storm does occur,  damaging traffic will be limited to only a percentage of your total bandwidth capacity.

 

Resilience: Unidirectional Link Detection (UDLD)

Unidirectional link issues happen when a fiber cable is damaged or misinstalled and causes a loop that has the potential to disrupt the entire network.

A switch with UDLD prevents this type of loop by shutting down the port where a unidirectional link is detected. This keeps your network stable and more resilient against common causes of fiber-link errors.

 

Efficiency: Equal-Cost Multi-Path (ECMP)

Meraki uses OSPF routing which directs packets by determining the lowest-cost path to a destination. However, in situations where multiple equal-cost paths are available, some paths may be underutilized.

With Equal-Cost Multi-Path (ECMP), the traffic can be load-balanced across multiple equal-cost paths, which promotes greater network efficiency.

 

Efficiency: Port Anomaly Detection

Port Anomaly Detection (formally called Spanning Tree Protocol /LAN Anomaly Detection) encompasses multiple enhancements for identifying and resolving spanning-tree and link issues. With the upgrade, the switch port icon indicates physical link errors and excessive link-status changes (STP issues).  The individual switch ports will also display orange or red in the dashboard when these types of issues are detected.

More broadly, Anomaly Detection furthers Meraki’s mission of providing in-depth visibility into your network. By providing detection of erroneous network behavior, we help ensure network stability and scalability.
