To configure DHCP option 82:
NOTE:
Replace values displayed in italics with values for your configuration.
1.
Specify DHCP option 82 for the BOOTP server:
•
On all interfaces that connect to the server:
[edit forwarding-options helpers bootp]
user@switch#
set
dhcp-option82
•
On a specific interface that connects to the server:
[edit forwarding-options helpers bootp]
user@switch#
set interface ge-0/0/10 dhcp-option82
The remaining steps are optional. They show configurations for all interfaces; include
the specific interface designation to configure any of the following options on a
specific interface:
2.
To configure a prefix for the circuit ID suboption (the prefix is always the hostname
of the switch):
[edit forwarding-options helpers bootp]
user@switch#
set dhcp-option82 circuit-id
prefix
hostname
3.
To specify that the circuit ID suboption value contains the interface description rather
than the interface name (the default):
[edit forwarding-options helpers bootp]
user@switch#
set dhcp-option82 circuit-id
use-interface-description
4.
To specify that the circuit ID suboption value contains the VLAN ID rather than the
VLAN name (the default):
[edit forwarding-options helpers bootp]
user@switch#
set dhcp-option82 circuit-id
use-vlan-id
5.
To specify that the remote ID suboption is included in the DHCP option 82 information:
[edit forwarding-options helpers bootp]
user@switch#
set dhcp-option82
remote-id
6.
To configure a prefix for the remote ID suboption (here, the prefix is the MAC address
of the switch):
[edit forwarding-options helpers bootp]
user@switch#
set dhcp-option82 remote-id
prefix
mac
7.
To specify that the prefix for the remote ID suboption is the hostname of the switch
rather than the MAC address of the switch (the default):
[edit forwarding-options helpers bootp]
user@switch#
set dhcp-option82 remote-id prefix hostname
