Multi-Queue Requirements and Limitations

Multi-Queue An acceleration feature on Security Gateway that configures more than one traffic queue for each network interface. Multi-Queue assigns more than one receive packet queue (RX Queue) and more than one transmit packet queue (TX Queue) to an interface. Multi-Queue is applicable only if SecureXL is enabled (this is the default). Acronym: MQ. only supports Security Gateways / Cluster Two or more Security Gateways that work together in a redundant configuration - High Availability, or Load Sharing. Members with two or more CPU cores.

Multi-Queue only supports interfaces that use these drivers:

Driver	Max Speed	Interface / Driver Description
igb	1 Gbps	Intel® Network Adapter Driver for PCIe 1 Gigabit Ethernet Network
ixgbe	10 Gbps	Intel® Network Adapter Driver for PCIe 10 Gigabit Ethernet Network
i40e	40 Gbps	Intel® Network Adapter Driver for PCIe 40 Gigabit Ethernet Network
i40evf	40 Gbps	Intel® i40e driver for Virtual Function Network Devices
ice	25 Gbps	Intel® Network Adapter Driver for E810 Series Devices
mlx5_core	40 Gbps	Mellanox® ConnectX® mlx5 core driver
ena	20 Gbps	Elastic Network Adapter in Amazon® EC2
virtio_net	10 Gbps	VirtIO paravirtualized device driver from KVM®
vmxnet3	10 Gbps	VMXNET Generation 3 driver from VMware®

Multi-Queue does not use network interfaces that are currently in the down state.

The number of traffic queues is limited by the number of CPU cores and the type of interface driver:

Note - Configuring Multi-Queue settings on an interface might temporarily interfere with traffic to that interface.

For example, configuring Multi-Queue settings on an interface while you are connected to that interface over SSH might close the SSH connection.
