The TOTALRATE parameter specifies the size of a bandwidth pool for specific network classes on the host. Virtual machines and containers can borrow bandwidth from the pool for communicating with hosts from the corresponding network class. The parameter thus limits the total available outgoing traffic for a network class that virtual machines and containers can consume.
The parameter is set as <NIC>:<network_class>:<bandwidth_in_Kbps>. For example, to set the pool size to 4 Mbps for network class 1 on the Ethernet adapter enp0s5, set TOTALRATE to enp0s5:1:4000. Multiple entries can be separated by spaces, e.g., enp0s5:1:4000 enp0s6:2:8000.
