  2. From the QoS tree, double-click QoS Agent.

  3. Select the Configuration tab.

Variable definitions

The following table outlines the parameters of the Configuration tab.

Table 1. QoS Agent Configuration tab parameters
Variable Value
QosOperMode Specifies whether the QoS Agent support is enabled or disabled.
NVRamCommitDelay Specifies the maximum time before nonvolatile QoS data is written to NVRAM.
ResetToPartialDefaults Resets QoS configurations to default except for queue-set and buffering type.
ResetToDefaults Resets all policy information to factory default values.
QueueCfg Determines the queue set that is associated with all egress interfaces by default.
BufferingCaps Determines the method through which buffering resources are allocated to ports sharing a pool of buffers. The value of this attribute determines the level of buffer sharing or over-allocation that can take place among ports sharing a buffer pool. Higher levels of over-allocation increase the likelihood (under heavy load) of a relatively few number of ports consuming all the buffers in a pool, causing packets to be dropped on other ports due to buffer starvation.
UBPSupportLevel Sets the level of user-based policy support.
TrackStatistics Specifies the type of statistics tracking.
AQApplicationMode Specifies the behavior of Auto Qos application mode.
TrustedProcessingMode Indicates the QoS trusted processing mode status. The trusted processing mode parameter is available only for a mixed stack of ERS 5500 Series switches.
TrustedProcessingMode Trusted processing mode: partialDscpMapping (less QoS filters used) or fullDscpMapping (64 QoS filters used).
DappEnable DoS Attack Prevention Package for ERS 5600 switches only: disable (default), enableWithoutStatusTracking (enabled without logging messages), enableWithStatusTracking (enabled with logging messages).
DappMinTcpHdrSize Specifies the Dapp minimum TCP header size.
DappIpv4IcmpMaxLength Specifies the Dapp maximum length for IPv4 ICMP packets.
DappIpv6IcmpMaxLength Specifies the Dapp maximum length for IPv6 ICMP packets.
