This is an expected behavior; user must use a different tag for custom options.

Predefined DHCP tags which are not allowed for DHCP custom options are the following:

  • "time-servers" (tag 4) - Should use time-servers in web-UI/CLI
  • "domain-name" (tag 15) - Should use domain name in DNS webUI/CLI or set domain name in DHCP scope CLI
  • "x-display-manager" (tag 49) - Should use X-Window display manager in webUI/CLI
  • "int-local-callmgr" (tag 150) - Should use Call-manager in web-UI/CLI
  • "int-local-avaya-voip" (tag 176) - Should use Avaya IP-phone in web-UI/CLI
  • "int-local-avaya9600-voip" (tag 242) - Should use Avaya IP-phone in web-UI/CLI
  • "int-local-nortel-voip" (tag 128) - Should use Nortel IP phone in web-UI CLI
