Profile Overrides - Advanced Traffic Shaping

Activation Criteria

Use the drop-down menu to determine when the traffic shaper is invoked. Options include: vrrp-master, cluster-master, rf-domain-manager and Always. A VRRP master responds to ARP requests, forwards packets with a destination link MAC layer address equal to the virtual router MAC layer address, rejects packets addressed to the IP associated with the virtual router and accepts packets addressed to the IP associated with the virtual router. The solitary cluster master is the cluster member elected, using a priority assignment scheme, to provide management configuration and Smart RF data to other cluster members. Cluster requests go through the elected master before dissemination to other cluster members. The RF Domain manager is the elected member capable of storing and provisioning configuration and firmware images for other members of the RF Domain.

VRRP Group

Set the VRRP group ID from 1 - 255. VRRP groups is only enabled when the Establishment Criteria is set to vrrp-master.

Class Index

Set a class index from 1 - 4.

Max Buffers

Set this value to specify the queue length limit after which the queue starts to drop packets. Set the maximum queue lengths for packets. The upper length is 400 for access points.

RED Level

Set the packet queue length for RED. The upper limit is 400 for access points. The rate limiter uses the RED (random early detection ) algorithm for rate limiting traffic. RED is a queueing technique for congestion avoidance. RED monitors the average queue size and drops or marks packets. If the buffer is near empty, all incoming packets are accepted. When the queue grows, the probability for dropping an incoming packet also grows. When the buffer is full, the probability has reached 1 and all incoming packets are dropped.

RED Percent

Set a percentage (1 - 100) for RED rate limiting at a percentage of maximum buffers.
