Description: Specify the host name to be inserted in the DHCPDISCOVER and DHCPREQUEST message. The specified host name must start with a letter, end with a letter or digit, and have only letters, digits, and hyphen as interior characters; the maximal length is 63. By default, the host name is empty. When set an empty host name, means to clear the host name setting and use the default value to encode option 12.
What is swL3IpCtrlIpDhcpOption12HostName?
The host name string, up to 63 characters, encoded into DHCP option 12; it must start and end with a letter/digit and use only letters, digits, and hyphens in between. An admin sets a name like "core-sw-lobby" here so the switch is easy to identify in DHCP server logs; leaving it empty falls back to the device's default-generated name.
