Appendix C: Using IPv6 with Virtual Connect

IPv6 addresses in VC

Beginning with VC 4.10, Virtual Connect interconnect modules can be configured to use IPv6 addresses for
communication over an IPv6 management network.
IPv6 address configuration is controlled by the OA. To enable IPv6 addressing in the VC, select the IPv6

enable check box in the OA web GUI page or execute the appropriate OA command in the OA CLI. This is

an enclosure wide configuration and all VC modules in the enclosure enable IPv6 address configuration if
this option is selected through the OA.
Four types of IPv6 addresses can be acquired by VC when IPv6 is enabled:

1.

Link local address

2.

DHCPv6 based dynamic address

3.

EBIPAv6 address

4.

SLAAC-based router advertisement address

Link Local Address

The LLA is an automatically configured, SLAAC address based on the MAC address of the interface. This

address starts with the prefix 0xfe80 and has link-local scope.
An LLA is always configured when IPv6 is enabled. The only way to disable the LLA for VC is to disable IPv6

in the OA.
The LLA is usable for communicating with nodes within the same network. Packets sent with the LLA as the

source address cannot be routed.
The LLA is displayed on the OA web GUI as one of the addresses available for communication with the VC.
To access the VCM GUI page, the appropriate interface ID must be appended to the web address while

directing the browser to a particular VCM. For example, in Linux, if eth0 is the interface, it could be of the

form:

https://[fe80::2e27:d7ff:febe:60a2%eth0]

On Windows, if the interface ID is a number, for example 11, the web address becomes:

https://[fe80::2e27:d7ff:febe:60a2%11]

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.
