Figure 9. Example of the DHCP Option 12 Command
SNMP Support
A MIB object supports enabling and disabling the DHCP Option 12 feature. It is added in the
hpicfDhcpclient.mib. The hostname is retrieved from the MIB variable SYSNAME. Validity checks
on the name include:
■ The name starts with a letter, ends with a letter or a digit, and can have letters, hyphens, or
digits in between the first and last characters.
■ The maximum size supported for a hostname is 30 characters. If SYSNAME is more than 30
characters, then DHCP Option 12 will not be included in the packet.
■ The minimum number of characters supported for a hostname is one character. If the
SYSNAME in the MIB is null, then DHCP Option 12 will not be included in the packet.
