show datapath-config
This command displays the current DPDK-based settings for the datapath. The command has no arguments.
Syntax
show datapath-config
Output Example
As shown below, this command displays key core and memory configuration of the deployment. Exact output is dependent on your environment.
For example, you may or may not be using hyperthreading, which establishes physical vs. logical CPU considerations. Some hypervisors do not present physical and logical cores such that the SBC can differentiate between CPU types using uppercase and lowercase letters. In these conditions, the SBC displays all CPUs with uppercase letters. When supported by the platform, however, the SBC displays a second logical core of each physical core using lowercase lettering.
Bear in mind that the second, logical core of a physical core cannot be assigned to any DPDK function. The system automatically sets them to signaling.
A VM with 8 vCPUs and hyper-threading enabled assigns the pairing of the cores as follows:
- Cores (0,4)
- Cores (1,5)
- Cores (2,6)
- Cores (3,7)
