In Linux, sysctl allows an administrator to modify kernel parameters at runtime. You can modify interface-level network sysctls using the tuning Container Network Interface (CNI) meta plugin. The tuning CNI meta plugin operates in a chain with a main CNI plugin as illustrated.

To modify kernel parameters and interface attributes at runtime in {product-title}, you can use the tuning Container Network Interface (CNI) meta plugin. The plugin operates in a chain with a main CNI plugin and allows you to change sysctls and interface attributes such as promiscuous mode, all-multicast mode, MTU, and MAC address.

The main CNI plugin assigns the interface and passes this interface to the tuning CNI meta plugin at runtime. You can change some sysctls and several interface attributes such as promiscuous mode, all-multicast mode, MTU, and MAC address in the network namespace by using the tuning CNI meta plugin.
