1.5 Target device naming
The IPv4 mode connection can be either a stateful (configuration and IP
addresses are provided by the server) or a stateless (the switch normally
receives the IP address and router address dynamically from the router) auto-
configuration. Switch firmware upgrades and emergency boot firmware upgrades
are supported for both TFTP and FTP servers while in IPv4 mode.
The IPv6 mode is a stateless, auto-configuration connection. While in IPv6 mode,
switch firmware upgrades are only facilitated in FTP mode and emergency boot
firmware flash downloads cannot be performed. To perform a flash download,
you must temporarily connect to an IPv4 network with a TFTP server. KVM s4
client software 4.1 or higher is required for IPv6 function.
