HP Virtual Connect 8Gb 20-port Fibre Channel Module for c-Class BladeSystem - Manual (Page 302)

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.
