5. (Optional) You can use the exclude option to exclude a specific interface or a specified
range of interfaces from the group. For example:
[edit system services dhcp-local-server group boston]
user@host# set interface fe-1/0/1.1 upto fe-1/0/1.102
user@host# set interface fe-1/0/1.6 exclude
user@host# set interface fe-1/0/1.70 upto fe-1/0/1.80 exclude

Guidelines for Configuring Interface Ranges for Groups of DHCP Interfaces
This topic describes guidelines to consider when configuring interface ranges for named
interface groups for DHCP local server and DHCP relay. The guidelines refer to the
following configuration statement:
user@host# set interface interface-name upto upto-interface-name
•
The start subunit, interface interface-name , serves as the key for the stanza. The
remaining configuration settings are considered attributes.
•
If the subunit is not included, an implicit .0 subunit is enforced. The implicit subunit is
applied to all interfaces when autoconfiguration is enabled. For example, interface
ge-2/2/2 is treated as interface ge-2/2/2.0.
•
Ranged entries contain the upto option, and the configuration applies to all interfaces
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 0 (zero) subunit acts as a wildcard.
•
Interface stanzas defined within the same router or switch context are dependent and
can constrain each other—both DHCP local server and DHCP relay are considered.
Interface stanzas defined across different router (switch) 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 ge-1/0/0.10 is the start subunit for both.
interface ge-1/0/0.10 upto ge-1/0/0.30
interface ge-1/0/0.10
