Appendix C: Using IPv6 with Virtual Connect 302

DHCPv6 address

To obtain a DHCPv6 address from a DHCPv6 server in the management network, the DHCPv6 option must

be enabled in the OA web GUI or enabled through the OA CLI. The IPv6 option should also be enabled.
The DHCPv6 address is a global address and packets with this address can be routed.

IMPORTANT:

If EBIPAv6 is enabled, VC does not configure a DHCPv6 address from the

DHCPv6 server even if the DHCPv6 option is enabled.

The DHCPv6 address is displayed in the OA web GUI as one of the addresses available for communication

with the VC.
VC 4.10 does not support stateless DHCPv6.

EBIPAv6 address

EBIPAv6 is the mechanism for configuring fixed addresses for VC management interfaces. This occurs

through the OA web GUI or through the OA CLI. The EBIPAv6 option precludes the DHCPv6 option.

Therefore, with EBIPAv6 enabled, VC does not configure a DHCPv6 address even if the DHCPv6 option is
enabled.
The EBIPAv6 address is displayed on the OA web GUI as one of the addresses available for communication

with the VC.
All OA, iLO, and VC management addresses must belong to a single network, in the same subnet. OA, iLO,
and VC must be able to communicate to enable VC functionality. For best practices, be sure that the

management network is lightly loaded and isolated from the data network.

Switching between EBIPAv6 and DHCPv6

If VC has a valid DHCPv6 address and EBIPAv6 is enabled, the EBIPAv6 configuration takes effect only when

the DHCPv6 address fails to renew and expires. This is dependent on the DHCPv6 lease time. To make an

EBIPAv6 address configuration apply immediately, a reboot of VC is required.
Likewise, when EBIPAv6 is disabled and DHCPv6 is enabled, a DHCPv6 address solicitation starts in the next

60 seconds. This is because the EBIPAv6 address configuration refreshes every 60 seconds.

Router advertisement-based addresses

VC can configure SLAAC addresses using prefixes supplied by Router Advertisements sent by routers in the

network. The SLAAC option must be enabled in the OA web GUI or via the OA CLI. The IPv6 enable option

must also be enabled.
VC can configure more than one RA-based SLAAC address on its management interface. It reports up to a
maximum of 6 addresses to the OA as addresses available for access to VC. These addresses are displayed

on the OA web GUI as addresses available for communication with VC.

Domain static addressing

Beginning with VC 4.10, VC supports domain static addressing with an IPv6 address. This can be configured

through the VCM web GUI or the VCM CLI.
