About IPv4-IPv6-based network support on the Access Appliance

Note:

This topic applies only to eth1 of the appliance nodes. This port is used for appliance management and not for the Veritas Access software.

You can assign either an IPv4 or an IPv6 address to the eth1 interface.

Consider the following points for IPv6 addresses:

You can configure a pure IPv6 network for the appliance. An IPv6 address can be configured for the appliance node management interface (eth1). However, Call Home is not supported in a pure IPv6 network configuration.
Only global addresses can be used, not addresses with link-local or node-local scope. Global-scope and unique-local addresses are both treated as global addresses by the host.
Global-scope IP addresses refer to the addresses that are globally routable. Unique-local addresses are treated as global.
You cannot use both an IPv4 and an IPv6 address in the same command. For example, do no use set network interface gateway=1.1.1.1 ip=9ffe::9 netmask=255.255.255.0.
Embedding the IPv4 address within an IPv6 address is not supported. For example, you cannot use an address like 9ffe::10.23.1.5.
You can enter only one IPv6 address for a network interface card (NIC).
Network File System (NFS) protocol is supported over an IPv4 network on the appliance.
You can add an IPv6 address using the set network interface command. This command can only be run on a node that is not a part of the cluster. The set network interface command can set only the eth1 network interface.
