The following DHCP functionalities are not supported on ACX Series routers:
•
Authentication for DHCP relay agents.
•
DHCP server configuration.
•
DHCP snooping to enable the router differentiate between trusted and untrusted
interfaces.
•
DHCP liveness detection.
•
DHCPv6 relay agent in IPv6 networks.
•
Dynamic profiles for DHCP.
•
DHCP relay agent in an L2VPN (dhcp-relay statement at the [edit routing-instances
routing-instance-name protocols l2vpn] hierarchy level)
•
The DHCP relay agent does not add VPN identifiers to the incoming DHCP requests
before it relays them to the DHCP server. Therefore, transmission of DHCP packets
between different virtual routing and forwarding (VRF) instances is not supported.
•
DHCP relay agent does not support the following operations:
•
DHCP relay agent authentication by including the authentication statement at the
[edit forwarding-options dhcp- relay] hierarchy level for global configuration, and
similarly for a named group of interfaces
•
DHCP relay agent snooping by including the allow-snooped-clients option in the
overrides statement at the [edit forwarding-options dhcp-relay] hierarchy level for
global configuration, and similarly for a named group of interfaces or a specific
interface
•
DHCP snooped packet forwarding by including the forward-snooped-clients statement
at the [edit forwarding-options dhcp-relay] hierarchy level for global configuration,
and similarly for a named group of interfaces or a specific interface
•
Overriding default DHCP relay agent configuration options by including the overrides
statement and its subordinate statements at the [edit forwarding-options dhcp-relay],
[edit forwarding-options dhcp-relay group group-name], and [edit forwarding-options
dhcp-relay group group-name interface] hierarchy levels.
The DHCP functionality supports the DHCP vendor class identifier option (option 60).
This support allows DHCP relay to compare option 60 strings in received DHCP client
packets against strings that you configure on the router. You can use the DHCP relay
option 60 feature when providing converged services in your network environment—option
60 support enables DHCP relay to direct client traffic to the specific DHCP server (the
vendor-option server) that provides the service that the client requires. Otherwise, as
another option, you can configure option 60 strings to direct traffic to the DHCP local
server in the current virtual router.
