Quotes can be used inside parameter values by replacing all quote characters
with the string ``"``. They will be replaced with literal quote characters
when generating dhcpd.conf.
Example Example
^^^^^^^ ^^^^^^^
.. opcmd:: set service dhcp-server shared-network-name dhcpexample subnet 192.0.2.0/24 static-mapping example static-mapping-parameters "option domain-name-servers 192.0.2.11, 192.0.2.12;" .. opcmd:: set service dhcp-server shared-network-name dhcpexample subnet 192.0.2.0/24 static-mapping example static-mapping-parameters "option domain-name-servers 192.0.2.11, 192.0.2.12;"
Override the static-mapping's dns-server with a custom one that will be sent only to this host. Override the static-mapping's dns-server with a custom one that will be sent
only to this host.
.. opcmd:: set service dhcp-server shared-network-name dhcpexample subnet 192.0.2.0/24 static-mapping example static-mapping-parameters "option pxelinux.configfile "pxelinux.cfg/01-00-15-17-44-2d-aa";"
An option that takes a quoted string is set by replacing all quote characters
with the string ``"`` inside the static-mapping-parameters value.
The resulting line in dhcpd.conf will be
``option pxelinux.configfile "pxelinux.cfg/01-00-15-17-44-2d-aa";``.
