Release Information

Statement introduced in JUNOS Release 8.3.

Description

Include the agent-circuit-id suboption (suboption 1) of the DHCP relay agent information option (option 82) in DHCP packets destined for a DHCP server.

The format of the agent-circuit-id information for Fast Ethernet or Gigabit Ethernet interfaces that do not use virtual local area networks (VLANs) or stacked VLANs (S-VLANs) is as follows:


                        
                           (fe | ge)-fpc/pic/port

The format of the agent-circuit-id information for Fast Ethernet or Gigabit Ethernet interfaces that use VLANs is as follows:


                        
                           (fe | ge)-fpc/pic/port:vlan-id

The format of the agent-circuit-id information for Fast Ethernet or Gigabit Ethernet interfaces that use S-VLANs is as follows:


                        
                           (fe | ge)-fpc/pic/port:svlan-id-vlan-id

The remaining statement is explained separately.
