IPv6 and the NAS server
On the NAS server, wherever an IP address is specified, it is possible to add IPv4 or IPv6 addresses. If the NAS server is configured with IPv6 addresses, clients can connect to it using IPv6. However, to connect to it from both IPv4 and IPv6 clients, it is necessary to configure both IPv4 and IPv6 addresses.
Using the NAS Manager with IPv6
It is possible to use the NAS Manager to configure IPv6 addresses for file-serving and non-file serving interfaces, routes and name services.
For example, the Administrator can set an IPv6 address for ag1 on the file-serving interfaces. The format is <address>/<prefix length> as shown below:
This page is also where an IPv6 address is configured for the Admin Services Node. This is necessary in order to launch the NAS Manager over IPv6. It is not possible to configure an IPv6 address on a cluster node.
Using CLI commands with IPv6
Each CLI command that accepts IPv4 addresses also accepts IPv6 addresses, for example, the evs command as shown below:
> evs create -i 2001:db8::/64 -p ag2 -n 1
Some commands, for example ping, have an IPv6 variant ping6, as shown below:
> ping6 -c10 2001:db8:220a:480:baac:6fff:fe80:5962 32 bytes from 2001:db8:220a:480:baac:6fff:fe80:5962 icmp_seq=0 time=6 ms 32 bytes from 2001:db8:220a:480:baac:6fff:fe80:5962 icmp_seq=1 time <1 ms 32 bytes from 2001:db8:220a:480:baac:6fff:fe80:5962 icmp_seq=2 time <1 ms
IPv6 and non-file serving interfaces
On the NAS server, an IPv6 address can be configured on the Admin Services Node - eth0 or eth1. However, on the SMU, IPv6 addresses are only configurable on eth0 and not on eth1. This is because on an external SMU, only eth0 is considered to be a public interface. The eth0 interface must always retain an IPv4 address. The IPv6 configuration is in addition to the IPv4 configuration.
The Administrator can configure a static IPv6 IP address for an external SMU as shown in the example below or use the SLAAC option where the address is generated from router advertisements.
The Administrator can use this address to launch the external SMU GUI (NAS Manager) and it also enables the external SMU to manage a server with an IPv6 Admin Services Node address.
