Multi-Queue and Dynamic Split must have an external NIC to add more than 2 CoreXL SNDs on a 6500 appliance Technical Level
  • Dynamic Split cannot add more than two CoreXL SNDs on a 6500 appliance.

  • Dynamic Split does not balance CoreXL_SNDs and CoreXL_FWs. No new CoreXL SNDs are added above the default CoreXL SND.


The onboard interfaces on 6500 appliances use the IGB driver, which usually supports more than two RX queues, but the I211 controller on the onboard interfaces supports only up to two RX queues. Therefore, when a user enables Multi-Queue or Dynamic Split and uses only an onboard network interface, the number of CoreXL SNDs is limited to two.
