C.8 General Registry Values
This section provides information on general registry keys that affect Mellanox driver operation.
LocalEndpointMaxAge 5 The maximum number of runs of the local end point DB monitor,
before an unused local endpoint is removed. The endpoint age is
zeroed when it is used as a source in the send flow or a destination
in the receive flow. Each monitor run will increment the age of all
non VMQ local endpoints. When LocalEndpointMaxAge is
reached - the endpoint will be removed.
The valid values are 1 up to 20.
Note: This registry value is not exposed via the UI.
LocalEndpointMonito-
rInterval
60000 The time interval (in ms) between each 2 runs of the local end point
DB monitor, for aging, unused local endpoints. Each run will incre-
ment the age of all non VMQ local endpoints.
The valid values are 10000 up to 1200000.
Note: This registry value is not exposed via the UI.
EnableQPR 0 Enables query path record.
The valid values are:
• 0 - disable
• 1 - enable
McastQueryRespon-
seInterval
2 The number of runs of the multicast monitor (which runs every 30
seconds) allowed until a response to the IGMP/MLD queries is
received. If after this period a response is not received, the driver
leaves the multicast group.
The valid values are 1 up to 10.
Note: This registry value is not exposed via the UI.
Value Name Default Value Description
MaxNumRssCpus 4 The number of CPUs that participate in the RSS.
The Mellanox adapter can open multiple receive rings, each ring
can be processed by a different processor. When RSS is disabled,
the system opens a single Rx ring.
The Rx ring number that is configured should be powered of two
and less than the number of processors on the system.
Value Type: DWORD
The valid values are 1 up to number of processors on the system.
