Enabling the Multiqueue Feature on IPFEs

4.2 Enabling the Multiqueue Feature on IPFEs

After the deployment of DSR on IPFEs is complete, you can perform the following procedure to enable the Multiqueue feature to increase the performance of IPFE.

Note:

This procedure is not applicable for DSR 8.5 and later.
This procedure is applicable for DSR 8.5 or earlier if the prerequisites, that is, updating the IPFE image and flavor, for the Multiqueue feature is complete.

Ensure that the DSR deployment on IPFEs is complete.
Update the IPFE image and flavor as described in Prerequisite for Multiqueue on IPFE.

Add the following lines to the network script of the interface that you want to change:
```
DEVICE=eth
TYPE=Ethernet
ETHTOOL_OPTS="-L ${DEVICE} combined <no_of_vCPUs>
```
For example, to set the number of queues to number of vCPUs, edit /etc/sysconfig/network-scripts/ifcfg-eth_interface to set the multiqueue value to the number of vCPUs.
Execute the service network restart command as root user to restart the network.
Execute the ethtool -l <eth_interface> command to check the setting.
