Chapter 18: Setting IPv4 and IPv6 Management
198
Overview
If you use the AlliedWare Plus web interface to change the IP address of
the switch, the web connection to the switch is lost. In order to maintain a
connection with the switch, it is necessary to also have a local connection
if you are going to change the IP address with the web interface. For
information about a local connection to the switch, see the AlliedWare
Plus Management Software Command Line Interface User’s Guide.
The features listed in Table 3 require that the switch is assigned a
management IP address in the web interface. The switch uses the
address to identify itself to other network devices, such as TFTP servers
and Telnet clients.
You can assign the switch an IPv4 address and an IPv6 address, but only
one of each type. However, as shown in the table, a management IPv6
address only supports the TACACS+ client. To use features that are not
supported by an IPv6 address, you must assign the switch an IPv4
address instead of or, in addition to, an IPv6 address.
Note
In the Command Line Interface, there are additional features that
require either an IPv4 or IPv6 address.
