This topic describes guidelines to consider when configuring interface ranges for named
interface groups for a DHCP local server. The guidelines refer to the following configuration
statement:
user@host# set interface interface-name upto upto-interface-name
The start subunit, interface interface-name
remaining configuration settings are considered attributes.
If the subunit is not included, an implicit

ge-2/2/2 interface ge-2/2/2.0
Ranged entries contain the
within the specified range. The start of a ranged entry must be less than the end of the
range. Discrete entries apply to a single interface, except in the case of
autoconfiguration, in which a
Interface stanzas defined within the same router context are dependent and can
constrain each other—both DHCP local server and DHCP relay are considered. Interface
stanzas defined across different router contexts are independent and do not constrain
one another.
Each interface stanza, whether discrete or ranged, has a unique start subunit across a
given router context. For example, the following configuration is not allowed within
the same group because
interface ge-1/0/0.10 upto ge-1/0/0.30
interface ge-1/0/0.10
Two groups cannot share interface space. For example, the following configuration is
not allowed because the three stanzas share the same space and interfere with one
another—interface
ge-1/0/0.26
dhcp-relay group diamond interface ge-1/0/0.10 upto ge-1/0/0.30
dhcp-local-server group ruby interface ge-1/0/0.26
