Mesh QoS (Quality of Service) provides a data traffic prioritization scheme. QoS reduces congestion from excessive traffic. If there is enough bandwidth for all users and applications (unlikely because excessive bandwidth comes at a very high cost), then applying QoS has very little value. QoS provides policy enforcement for mission-critical applications and/or users that have critical bandwidth requirements when bandwidth is shared by different users and applications.
Mesh QoS helps ensure each mesh point on the mesh network receives a fair share of the overall bandwidth, either equally or as per the proportion configured. Packets directed towards clients are classified into categories such as video, voice and data packets within each category are processed based on the weights defined for each mesh point.
To create a meshpoint, see meshpoint-config-instance.
A meshpoint QoS policy is created from the (config) instance. To create a meshpoint QoS policy use the following command:
<DEVICE>(config)#meshpoint-qos-policy <POLICY-NAME>
nx9500-6C8809(config)#meshpoint-qos-policy test nx9500-6C8809(config-meshpoint-qos-test)#? Mesh Point QoS Mode commands: accelerated-multicast Configure accelerated multicast streams address and forwarding QoS classification no Negate a command or set its defaults rate-limit Configure traffic rate-limiting parameters on a per-meshpoint/per-neighbor basis clrscr Clears the display screen commit Commit all changes made in this session do Run commands from Exec mode end End current mode and change to EXEC mode exit End current mode and down to previous mode help Description of the interactive help system revert Revert changes service Service Commands show Show running system information write Write running configuration to memory or terminal nx9500-6C8809(config-meshpoint-qos-test)#
The following table summarizes the mespoint-qos-policy configuration commands.
Command |
Description |
---|---|
accelerated-multicast (meshpoint-qos-policy) | Configures accelerated multicast parameters |
rate-limit (meshpoint-qos-policy) | Configures the rate limits for this QoS policy |
no (meshpoint-qos-policy) | Negates a command or reverts settings to their default |
