Set configuration setting

  set <setting> <value>

  set net0/ip 192.168.0.100
  set net0/netmask 255.255.255.0
  set net0/gateway 192.168.0.1

  set dns 192.168.0.1

  set keep-san 1
  autoboot

  ifclose net0
  set net0/mac 52:54:00:12:34:56
  ifopen net0

  set esc:hex 1b            # ANSI escape character - "^["
  set cls ${esc:string}[2J  # ANSI clear screen sequence - "^[[2J"
  echo ${cls}

Set value of the specified configuration setting to the specified value.

The value will be interpreted according to the type specified as part of the setting name. For example, the command:

  set net0/ip:hex 0a:00:00:64

is equivalent to the command:

  set net0/ip:ipv4 10.0.0.100

If no type is explicitly specified, then the setting's default type will be used.

• show
• clear
• read
• inc
• config
• List of all iPXE settings
• List of all iPXE commands

You can use the config command to browse and edit settings interactively.

You can use the read command to prompt the user to enter a single setting.

Settings are generally applied immediately. For example, the command:

  set net0/ip 192.168.0.1

will immediately change the IPv4 address associated with the network interface “net0”. In some cases, further action may be required in order to apply a setting. For example, the command:

  set net0/mac 52:54:00:12:34:56

will not take effect properly until the network interface is closed and reopened. See the documentation on individual settings for further details.

Older versions of iPXE allowed ANSI escape sequences to be defined using code such as:

  set esc:hex 1b ; set cls ${esc}[2J ; echo ${cls}

This should instead be

  set esc:hex 1b ; set cls ${esc:string}[2J ; echo ${cls}
