After configuring a Cisco Meraki device's static IP address either from the dashboard or via the my.meraki.com Uplink configuration page, the device may report "Bad IP assignment configuration" in Dashboard. In the case that the device cannot get an ARP reply from its default gateway, it will revert back to using DHCP for its IP configuration. This is an intended function to bring the device online; if the device can't reach its default gateway, it will never report to Dashboard.
When a client is authenticated with an AD server through an MX appliance it authenticates once and holds those credentials locally. In situations where clients must be removed or forced to re-authenticate with the Active Directory server, there are two options:
The Cisco Meraki Dashboard offers network administrators the ability to monitor and manage individual network clients, which can be helpful for both administration and troubleshooting purposes. This article overviews the client details page for MR, MS and MX/Z1 networks. The client lists are all consolidated into Network-wide > Clients, which can then be filtered as shown below.
By default, all Cisco Meraki devices will distinguish between different clients based on their MAC address, but the MX in particular has the ability to identify clients based on IP address as well. This article outlines differences between the two options, use cases for each, as well as how to change client tracking in Dashboard.
Cisco Meraki devices will display their public IP address on their device status page. The device status page can be found for MX appliances by navigating to Monitor > Appliance status in Dashboard. On APs and switches, this can be found by going to the device listing page and then clicking a specific device (Monitor > Access points for APs and Monitor > Switches for switches). It is possible that this public IP address appears incorrect.
Before an Apple iOS device uses DHCP to obtain an IP address on a new network connection, it will first attempt to re-use the IP address configuration received from a previous networks DHCP server. The iOS device does not take into account whether the new network and previous network are different.
Configurations made on Dashboard are immediately saved on the cloud. However, the physical Cisco Meraki devices may take few moments to download those changes. This article explains how to monitor the configuration update status from the Dashboard to ensure that the Cisco Meraki devices are up to date.
NetFlow is a protocol for exporting metrics for IP traffic flows. NetFlow data is sent from a flow exporter to a flow collector. Services and applications that serve as NetFlow collectors are desgined to receive the NetFlow data sent from exporters, aggregate the information, and provide data visualization and exploration tool sets.
Cisco Meraki devices can identify the hostname of a client device using NetBIOS, Bonjour and DHCP. In some instances, the detected hostname may undesirable. For example, 2 devices on the same network with identical hostnames or a device that has been identified by its MAC address. The hostname can be overridden within Dashboard by configuring a manual value.
In Dashboard, useful status information can be gathered at a glance from the colored icons representing each device on the Monitor > Access points, Monitor > Switches, or Monitor > Appliance status pages. For example, It can be determined what a given device is, whether it is active or not, or if an access point is in repeater mode or not. This article will clarify which icons are displayed for each device and this information is also available by hovering the mouse above the icon in question
The factors below should be considered when troubleshooting suspected blocked or unauthorized access: Unauthorized and users may still access web sites on the meraki.com domain if they are not blocklisted. This bandwidth will not appear in dashboard.
Dashboard gives users the ability to download and export several types of data including Client data. When viewing this exported data, you may run into difficulties deciphering the time and date values as they are exported in the EPOCH time standard. The following steps explain how to export your client usage data, and convert that data into a more recognizable format:
The Live tools available under Monitor > Appliance Status > Live Tools provide useful information for troubleshooting network issues on the MX Security Appliance. Each of these tools is able to pull information from, or interact with, the MX appliance in real-time. Each section below will provide information regarding the different tools and how they can be used.
