VMQ Processor Configuration with the Cisco Nexus 1000V

VMQ allows the network traffic received on an adapter to be spread over multiple CPU cores which
provides better performance. The following two factors are important in determining if the VMQ
operates correctly:
The above two factors can be configured so that the same CPU core is not used by multiple NICs.
Changing the RSS registry is a disruptive operation and causes the Ethernet adapter to flap.
Note
The Cisco Nexus 1000V supports the following port-channel operational modes: Link Aggregation
Control Protocol (LACP) and vPC.
The LACP utilizes the same Subgroup id for all the members of a port-channel. The RSS Base CPU and
Max RSS Processors should be configured with same value for all member ports.
MAC pinning / manual pinning port-channel use multiple subgroup ids within the members of the
port-channel. Therefore, the RSS Base CPU and Max RSS processors should be configured so that the
same CPU core is not used by multiple NICs.

Changing the RSS Registry

To change the RSS registry, perform the following steps:
Open View Network Connections from the Server Manager or Control Panel or by typing ncpa.cpl from
Step 1
a command line.
Right-click the adapter and choose properties.

Certain adapters allow the MTU change only through their own adapter manager. For example,
the MTU of the Cisco VIC cards can be changed thorugh the UCSM or ILO.
The receive side scaling (RSS) CPU number determines the lowest CPU core that can be used by
RSS.
The maximum number of RSS CPU determines how many CPU cores can be used by RSS.
