Field name
Description
Enable TCP
Receive Side
Scaling
RSS distributes network receive processing across multiple CPUs in
multiprocessor systems.
If this option is selected, network receive processing is shared across processors
whenever possible.
If this option is not selected, network receive processing is handled by a single
processor, even if additional processors are available.
Enable IPv4 RSS
If this option is selected, RSS is enabled on IPv4 networks.
If this option is not selected, RSS is not enabled on IPv4 networks.
Enable TCP-IPv4
RSS
If this option is selected, RSS is enabled for TCP transmissions on IPv4 networks.
If this option is not selected, RSS is not enabled for TCP transmissions on IPv4
networks.
Enable IPv6 RSS
If this option is selected, RSS is enabled on IPv6 networks.
If this option is not selected, RSS is not enabled on IPv6 networks.
Enable TCP-IPv6
RSS
If this option is selected, RSS is enabled for TCP transmissions on IPv6 networks.
If this option is not selected, RSS is not enabled for TCP transmissions on IPv6
networks.
Enable IPv6
Extension RSS
If this option is selected, RSS is enabled forIPv6 extensions.
If this option is not selected, RSS is not enabled for IPv6 extensions.
Enable TCP-IPv6
Extension RSS
If this option is selected, RSS is enabled for TCP transmissions on IPv6 networks.
If this option is not selected, RSS is not enabled for TCP transmissions on IPv6
networks.
Adding virtualized servers: configuring vEthernet interfaces
With the Cisco NX-OS Adapter-FEX feature, there are two ways to logically configure the Cisco Nexus
5548UP Switches virtual Ethernet (vEthernet) interfaces for connectivity to the servers.
•
Static vEthernet creation of the Cisco Nexus 5548UP Switches is the standard for virtual servers.
Cisco Nexus 5548UP Switches on the Converged System are configured similarly and conform to
standards, which helps with identification and troubleshooting. Valid interface IDs should be less
than 32768.
•
Dynamic vEthernet creation of the Cisco Nexus 5548UP Switches entails less logical
configuration but sacrifices some customization. vEthernet interfaces are created dynamically as
the server boots up, with IDs greater than 32768. Once the vEthernet interfaces are created and
the configuration is saved, the interfaces remain the same across reboots. This method is not a
best practice; therefore, it is not documented.
