You must globally enable DHCP snooping by using the ip dhcp snooping global configuration command for
any DHCP snooping configuration to take effect.
When the option-82 feature is enabled, the default remote-ID suboption is the switch MAC address. This
command allows you to configure either the switch hostname or a string of up to 63 ASCII characters (but
no spaces) to be the remote ID.
If the hostname exceeds 63 characters, it will be truncated to 63 characters in the remote-ID configuration.
