Chapter 17: Setting IPv4 and IPv6 Management

188

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 4 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.

In the Command Line Interface, there are additional features that 
require either an IPv4 or IPv6 address.
