The following table outlines the parameters of the Configuration tab.
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 condigurations to deafult ecept for quque-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 | Dapp minimum TCP header size |
DappIpv4IcmpMaxLength | Dapp maximum length for IPv4 ICMP packets |
DappIpv6IcmpMaxLength | Dapp maximum length for IPv6 ICMP packets |
