Ethtool. Ethtool is a Linux-specific tool with corresponding support in the kernel where each net device must register its own callbacks for the supported operations. The current implementation uses the igb/ixgbe modified Linux drivers for ethtool support. Ethtool is not supported in i40e and VMs (VF or EM devices).

See full list on linux.die.net ethtool -G eth0 tx 4096 rx 4096. This command will change RX and TX values to 4096 at every boot. 2. Optimizing for virtual environments. 2.1. Network interfaces. Using VyOS as guest machine supported in many hypervisors, and this feature is very often actively used by our customers. Apr 22, 2020 · With 6 Cores you should have 4 tx rx ring buffers activated on the nic card. so you should be able to use 4 CPUs for traffic forwarding. One of the reason to just being using one could be because transfer was UDP. This was the case? If not check this commands: sudo ethtool -S ethX with X your interface. Multi-Queue / Receive-Side Scaling (RSS) is an Intel network driver technology that enables the efficient distribution of received packets across multiple CPU cores in multi- core systems. Set custom RX queue weights with ethtool -X. The above command specifies a weight of 6 for rx queue 0 and 2 for rx queue 1, pushing much more data to be processed on queue 0.

Aug 15, 2018 · ethtool -l <ethX> - shows the number of Tx and Rx queues that are setup, which usually should match the number of CPU cores to be used. ethtool -g <ethX> - shows the number of packet buffers for each Tx and Rx queue; too many and we're wasting memory, too few and we risk dropping packets under heavy throughput pressure.

Ethtool Input Plugin. The ethtool input plugin pulls ethernet device stats. Fields pulled will depend on the network device and driver. Configuration: Slave queue ID: 0 Now let's go back to the test server and check what happen on the continous ping made to our bonding server 64 bytes from 172.20.43.110: icmp_seq=84 ttl=64 time=0.437 ms Once the adapter name is know the "ethtool -S" command can be used to display low level statistics which you can use to identify a duplex mismatch. First, if the RED counters are going up the adapter is in half duplex mode. If the "tx_abort_late_coll" counter is climbing then the chances are the switch it is connected to is in full duplex mode. Now, I wanted to restrict 1 RX queue and 2 TX queues for my DPDK application. I am trying to set the same using ethtool but it is throwing below error: [[email protected] ~]$ sudo ethtool -L eth1 rx 1 tx 2 Cannot set device channel parameters: Invalid argument I can set combined queues = 2 but not specific RX / TX queues.

Valid for all IP based flow-types. action N Specifies the Rx queue to send packets to, or some other action. -1 Drop the matched flow -2 Use the matched flow as a Wake-on-LAN filter 0 or higher Rx queue to route the flow context N Specifies the RSS context to spread packets over multiple queues; either 0 for the default RSS context, or a value returned by ethtool -X... context new. vf N Specifies the Virtual Function the filter applies to. • Destination queue is selected in combination with an indirection table: queue = indirection_table[rss_hash(packet)] • It is possible to configure the indirection table using ethtool by simply applying weights to each RX queue.

The ethtool command enables you to query or control the network driver and hardware settings. It takes the device name (like swp1) as an argument. When the device name is the only argument to ethtool, it prints the

Maximum queue size. Before processing the data by the TCP/UDP layer, your system puts the data in the kernel queue. The net.core.netdev_max_backlog value specifies the maximum number of packets to put in the queue before delivery to the upper layer. The default value is not enough for a high network load, so simply increasing this value cures ...
