Juniper EX3400 Features Guide

The following examples show several possible formats for the DHCP option information
when you specify the prefix statement for Fast Ethernet (fe) or Gigabit Ethernet (ge)
interfaces with S-VLANs.
•
If you include only the hostname in the prefix for Fast Ethernet or Gigabit Ethernet
interfaces with S-VLANs:
hostname:(fe | ge)-fpc/pic/port:svlan-id-vlan-id
•
If you include only the logical system name in the prefix for Fast Ethernet or Gigabit
Ethernet interfaces with S-VLANs:
logical-system-name:(fe | ge)-fpc/pic/port:svlan-id-vlan-id
•
If you include only the routing instance name in the prefix for Fast Ethernet or Gigabit
Ethernet interfaces with S-VLANs:
routing-instance-name:(fe | ge)-fpc/pic/port:svlan-id-vlan-id
•
If you include both the hostname and the logical system name in the prefix for Fast
Ethernet or Gigabit Ethernet interfaces with S-VLANs:
host-name/logical-system-name:(fe | ge)-fpc/pic/port:svlan-id-vlan-id
•
If you include both the logical system name and the routing instance name in the prefix
for Fast Ethernet or Gigabit Ethernet interfaces with S-VLANs:
logical-system-name;routing-instance-name:(fe | ge)-fpc/pic/port:svlan-id-vlan-id
•
If you include the hostname, logical system name, and routing instance name in the
prefix for Fast Ethernet or Gigabit Ethernet interfaces with S-VLANs:
host-name/logical-system-name;routing-instance-name:(fe |
ge)-fpc/pic/port:svlan-id-vlan-id
For Fast Ethernet or Gigabit Ethernet interfaces that use VLANs but not S-VLANs, only
the vlan-id value appears in the DHCP option format.
(DHCPv4) To configure a prefix with the option 82 information:
1. Specify that you want to configure option 82 support.
[edit forwarding-options dhcp-relay]
user@host# edit relay-option-82
2. Configure DHCP relay agent to insert the Agent Circuit ID, the Agent Remote ID, or
both.
•
To configure the Agent Circuit ID:
[edit forwarding-options dhcp-relay relay-option-82]
user@host# edit circuit-id
•
To configure the Agent Remote ID:
[edit forwarding-options dhcp-relay relay-option-82]
user@host# edit remote-id
3. Specify that the prefix be included in the option 82 information. In this example, the
prefix includes the hostname and logical system name.
