Dynamic change of the interface speed according to the interface utilization is also supported. The dynamic tuning is controlled by the [option]`dynamic` and the global [option]`dynamic_tuning` option in `tuned-main.conf`. `wake_on_lan`::: The [option]`wake_on_lan` option sets wake-on-lan to the specified value as when using the `ethtool` utility. + .Set Wake-on-LAN for device eth0 on MagicPacket(TM) ==== ---- [net] devices=eth0 wake_on_lan=g ---- ==== `coalesce`::: The [option]`coalesce` option allows changing coalescing settings for the specified network devices. The syntax is: + [subs="quotes"] ---- coalesce=__param1__ __value1__ __param2__ __value2__ ... __paramN__ __valueN__ ---- + Note that not all the coalescing parameters are supported by all network cards. For the list of coalescing parameters of your network device, use `ethtool -c device`. + .Setting coalescing parameters rx/tx-usecs for all network devices ==== ---- [net] coalesce=rx-usecs 3 tx-usecs 16 ---- ==== `features`::: The [option]`features` option allows changing the offload parameters and other features for the specified network devices. To query the features of your network device, use `ethtool -k device`. The syntax of the option is the same as the [option]`coalesce` option. + .Turn off TX checksumming, generic segmentation and receive offload ==== ---- [net] features=tx off gso off gro off ---- ==== `pause`::: The [option]`pause` option allows changing the pause parameters for the specified network devices. To query the pause parameters of your network device, use `ethtool -a device`. The syntax of the option is the same as the [option]`coalesce` option. + .Disable autonegotiation ==== ---- [net] pause=autoneg off ---- ==== `ring`::: The [option]`ring` option allows changing the rx/tx ring parameters for the specified network devices. To query the ring parameters of your network device, use `ethtool -g device`. The syntax of the option is the same as the [option]`coalesce` option. + .Change the number of ring entries for the Rx/Tx rings to 1024/512 respectively ===== ----- [net] ring=rx 1024 tx 512 ----- ===== `channels`::: The [option]`channels` option allows changing the numbers of channels for the specified network device. A channel is an IRQ and the set of queues that can trigger that IRQ. To query the channels parameters of your network device, use `ethtool -l device`. The syntax of the option is the same as the [option]`coalesce` option. + .Set the number of multi-purpose channels to 16 ===== ----- [net] channels=combined 16 ----- ===== + A network device either supports rx/tx or combined queue mode. The [option]`channels` option automatically adjusts the parameters based on the mode supported by the device as long as a valid configuration is requested. `nf_conntrack_hashsize`::: The [option]`nf_conntrack_hashsize` option sets the size of the hash table which stores lists of conntrack entries by writing to `/sys/module/nf_conntrack/parameters/hashsize`. + .Adjust the size of the conntrack hash table ==== ---- [net] nf_conntrack_hashsize=131072 ---- ==== `txqueuelen`::: The [option]`txqueuelen` option allows changing txqueuelen (the length of the transmit queue). It uses `ip` utility that is in package iproute recommended for TuneD, so the package needs to be installed for its correct functionality. To query the txqueuelen parameters of your network device use `ip link show` and the current value is shown after the qlen column. + .Adjust the length of the transmit queue ==== ---- [net] txqueuelen=5000 ---- ==== `mtu`::: The [option]`mtu` option allows changing MTU (Maximum Transmission Unit). It uses `ip` utility that is in package iproute recommended for TuneD, so the package needs to be installed for its correct functionality. To query the MTU parameters of your network device use `ip link show` and the current value is shown after the MTU column. + .Adjust the size of the MTU ==== ---- [net] mtu=9000 ---- ==== c sd t t|
