Chapter 35 DHCP Table 150 DHCPv6 LDRA (continued) LABEL Control DESCRIPTION Select the role for each port on the Switch. Client-facing: this is an interface on a DHCPv6 relay agent that forwards traffic towards the DHCPv6 client. A client-facing interface on this Switch can be a DSL port or an Ethernet port which connects another LDRA-enabled Switch or DSLAM. Network-facing: this is an interface on a DHCPv6 relay agent that forwards traffic towards the DHCPv6 server. A network-facing interface on this Switch should be an Ethernet port. Forbidden: select this to have the Switch not add any information to DHCPv6 requests it receives. The Switch drops all DHCPv6 requests for a VLAN if this is set and DHCPv6 LDRA is enabled on the VLAN. A client-facing port only accepts the following types of DHCPv6 messages and drops the others. SOLICIT(1), REQUEST(3), CONFIRM(4), RENEW(5), REBIND(6), RELEASE(8), DECLINE(9), INFORMATION-REQUEST(11), RELAY-FORW(12) A network-facing port only accepts the following types of DHCPv6 messages and drops the others. RELAY-REPLY(13), ADVERTISE(2), REPLY(7), RECONFIGURE(10) Note: You must configure at least one network-facing port on the Switch. Untrust Add Cancel VID LDRA Option18 Option37 Option18 (Interface ID) Info Option37 (Remote ID) Info Select Delete Cancel Note: Use the network-facing role for the Ethernet port you use as the uplink port to connect towards the DHCPv6 server. Use the client-facing role for an Ethernet port on the Switch that you use to connect a subtended (daisy-chained) LDRA-enabled Switch or DSLAM. Use the network-facing role for the uplink port on the subtended Switch or DSLAM. If an Ethernet port (ex. port 26) on the Switch is the uplink port that connects to the DHCPv6 server and you connect port 25 to another LDRA-enabled Switch or DSLAM, you must set port 26's role to network-facing and port 25's to client-facing. The port role on the other end of port 25 must be set to network-facing. Select Untrust Client to have the Switch drop all RELAY-FORW(12) type DHCPv6 messages. Click Add to create a new DHCPv6 LDRA entry. Click Cancel to begin configuring this screen afresh. This is the ID number of the VLAN group. Click the link to modify the LDRA entry's settings. This field displays whether LDRA is enabled or not on this VLAN. This field displays whether or not the system adds option 18 (Interface ID Info) to the client DHCPv6 requests forwarded for this VLAN. This field displays whether or not the system adds option 37 (Remote ID Info) to the client DHCPv6 requests forwarded for this VLAN. This field displays the option 18 (Interface ID) information to add to the client DHCPv6 requests forwarded for this VLAN to identify the interface which received the client message. This field displays the option 37 (Remote ID) information to add to the client DHCPv6 requests forwarded for this VLAN.

Control
Select the role for each port on the Switch.
Client-facing
: this is an interface on a DHCPv6 relay agent that forwards traffic towards
the DHCPv6 client. A client-facing interface on this Switch can be a DSL port or an
Ethernet port which connects another LDRA-enabled Switch or DSLAM.
Network-facing
: this is an interface on a DHCPv6 relay agent that forwards traffic
towards the DHCPv6 server. A network-facing interface on this Switch should be an
Ethernet port.
Forbidden
: select this to have the Switch not add any information to DHCPv6 requests it
receives. The Switch drops all DHCPv6 requests for a VLAN if this is set and DHCPv6 LDRA
is enabled on the VLAN.
A client-facing port only accepts the following types of DHCPv6 messages and drops the
others.
SOLICIT(1), REQUEST(3), CONFIRM(4), RENEW(5), REBIND(6), RELEASE(8),
DECLINE(9), INFORMATION-REQUEST(11), RELAY-FORW(12)
A network-facing port only accepts the following types of DHCPv6 messages and drops
the others.
RELAY-REPLY(13), ADVERTISE(2), REPLY(7), RECONFIGURE(10)
Note: You must configure at least one network-facing port on the Switch.
Note: Use the network-facing role for the Ethernet port you use as the uplink port to connect
towards the DHCPv6 server. Use the client-facing role for an Ethernet port on the
Switch that you use to connect a subtended (daisy-chained) LDRA-enabled Switch or
DSLAM. Use the network-facing role for the uplink port on the subtended Switch or
DSLAM. If an Ethernet port (ex. port 26) on the Switch is the uplink port that connects
to the DHCPv6 server and you connect port 25 to another LDRA-enabled Switch or
DSLAM, you must set port 26’s role to network-facing and port 25’s to client-facing.
The port role on the other end of port 25 must be set to network-facing.
