Follow these instructions to install net-snmp and test SNMP access to the cloud controller: Windows-based operating systems can use an open-source tool called net-snmp. Multiple tools exist to test SNMP functionality on various operating systems. When using v3, Cisco Meraki devices will use SHA1 for authentication and DES for privacy, with the configured password used for both. If v3 is selected, you will need to configure a username and password. SNMP v1/v2c sends the community string in plain text. Version 3 adds the ability to encrypt the communication between the manager (network management system) and the agent (Meraki device). Using SNMP to directly poll individual devices provides the ability to choose between SNMP v1/v2c or v3. These settings can be found under Network-wide > General > Reporting: Individual Meraki devices can also be polled locally. In this scenario, the SNMP traffic would stay within the local network and each device would need to be polled from the network management system. The following are supported when polling the dashboard: GetRequest and GetNextRequest snmp GET methods. Meraki uses the read-only community string type. This also affects the Wi-Fi Multimedia (WMM) priority of the traffic.Note: Meraki SNMP access only supports get requests, so no changes to the dashboard configuration can be made using SNMP.Ensure that upstream networking equipment also supports QoS prioritization.Select a value for the DSCP tag in the IP header on all incoming and outgoing IP packets to apply QoS prioritization to Layer 3 traffic.Ensure that uplink throughput settings are accurate.Priority allows the router to prioritize a given network flow relative to the rest of the network traffic:.Always set Priority for 8x8 services to P7 (highest priority).Click details next to the bandwidth slider control to specify asymmetric limits on uploads and downloads.Can be specified to ignore any limits specified for the whole network to obey the specified limits or to apply more restrictive limits than the network limits.Specify appropriate bandwidth limits for each type of traffic with the bandwidth slider control.Click Add an expression to create additional specifications for traffic that is shaped according to the same rule action.Create rules by specifying HTTP hostnames (for example, ) port numbers (such as 80) IP ranges (such as 192.168.0.0/16) or IP address range and port combinations (such as 192.168.0.0/16:80).Select from various predefined application categories such as Video & Music, Peer-to-Peer, or Email.Set Rule Definition (do one of the following):.Click Create a new rule to add a traffic shaping rule.Traffic-matching-specified rule sets can be shaped or prioritized. The rule action is enforced on all traffic that matches the specifications you select. There are two main components to each rule: the type of traffic to be limited or shaped (rule definition), and how that traffic should be limited or shaped (rule actions). Traffic shaping policies consist of a series of rules that are performed in the order in which they appear in the policy, similar to custom firewall rules. Here is where you will set QoS (bandwidth management) based on ports, IP, or MAC specific rules.
