| + | ===== Notes ===== | ||
| + | |||
| + | The configuration setting will be cleared only within the specified scope. This may reveal an underlying value for the setting within a child scope. For example, suppose that we already have a DNS server address obtained via DHCP, which we then override manually using the ''[[:cmd:set]]'' command: | ||
| + | |||
| + | iPXE> dhcp net0 | ||
| + | DHCP (net0 52:54:00:12:34:56).... ok | ||
| + | iPXE> show dns | ||
| + | net0.dhcp/dns:ipv4 = 192.168.0.1 | ||
| + | iPXE> set dns 8.8.8.8 | ||
| + | iPXE> show dns | ||
| + | dns:ipv4 = 8.8.8.8 | ||
| + | |||
| + | If we then ''clear'' the DNS server address within the top-level scope, the underlying value will be restored: | ||
| + | |||
| + | iPXE> show dns | ||
| + | dns:ipv4 = 8.8.8.8 | ||
| + | iPXE> clear dns | ||
| + | iPXE> show dns | ||
| + | net0.dhcp/dns:ipv4 = 192.168.0.1 | ||
