Installation and Operations Manual Introduction 7
IPv6 and Server Technology Products
Server Technology is introducing IPv6 “dual stack” support to the PDU product line. IPv6 has been designed to
succeed IPv4 as the dominant communications protocol for internet traffic, to avoid depletions of the IPv4 address
space, and to allow more IP address growth. Many devices already in use support IPv6.
IPv6 has several new operational methods:
Static IPv6 Address: The IPv6 equivalent of Static IPv4.
DHCPv6 Address: The IPv6 equivalent of a DHCP IPv4 address, also known as a “stateful” auto-
configuration of DHCPv6.
IPv6 Stateless Auto-Configured Address –(RFC 4862): An automatically-generated unique link-local IPv6
address used for client based configurations. This address is always present in the Server Technology dual
stack and cannot be disabled.
DHCPv6 Stateless Auto-Configured Address –(RFC 3736): A “stateless” Dynamic Host Configuration
Protocol (DHCP) service for IPv6 (DHCPv6). This address is used by nodes to obtain configuration
information, such as addresses of DNS recursive name servers that do not require the maintenance of any
dynamic state for individual clients.
Firmware –Protocol Support
IPv6 and IPv4 Protocols:
The firmware supports the following network IPv6 and IPv4 protocols:
DNS Ping
FTP (or SFTP) Server SNMPv1/2/3
FTP (or SFTP) Updates SNTP
HTTP or HTTPS
SMTP
Static IPv6 DHCPv6 (stateless and stateful)
Syslog SNMPv1/2/3 Traps
Telnet SSH
IPv4-Only Protocols:
The firmware supports the following network IPv4-only protocols:
Cisco EnergyWise
LDAP
Load Shedding *
RADIUS *
TACACS+
* = may work with IPv6 addresses, but not tested.

8Introduction Switched PDU
Installation and Operations Manual
Network-Enabled Modes
NOTES:
For all network-enabled modes described below, the PDU will set an auto-configured IPv6 address, and if IPv6 router announcements are
active, a stateless DHCP IPv6 address will also be set. Further, in all network-enabled modes, at least one IPv4 or one IPv6 address will
be active.
For maximum backward compatibility, the default network mode is “IPv4 only”.
Network disabled –No IPv4 or IPv6 addresses available.
IPv4 only, DHCP disabled (static IPv4) –If the IPv4 Static Address and Net Mask of the PDU are valid,
they will be set.
IPv4 only, DHCP enabled (DHCP IPv4) –The PDU will try to resolve an IPv4 DHCP address. If a DHCP
address cannot be obtained after 90 seconds, the PDU can: (1) optionally fall back to its static IPv4 settings,
or (2) indefinitely wait to acquire an address based on DHCP configuration settings. This setting is the
default.
Dual IPv6/IPv4, DHCP disabled (static IPv6/IPv4) –If the IPv6 Static Address and prefix of the PDU are
valid, they will be set. Otherwise, the PDU will attempt to use DHCPv6 to obtain an IPv6 address.
In addition, if the IPv4 Static Address and Net Mask of the PDU are valid, they will be set.
Dual IPv6/IPv4, DHCP enabled (DHCP IPv6/IPv4) –The PDU will try to resolve both its IPv6 and IPv4
addresses by DHCP. If both DHCP requests are answered, the primary DNS server of the PDU will become
the primary IPv6 DNS server, and the secondary DNS server of the PDU will become the primary IPv4
DNS server.
If only one of the DHCP requests is answered, the DNS servers of the PDU will map to the primary and
secondary DNS server from that request.
If a DHCP address cannot be obtained after 90 seconds, the PDU can: (1) optionally fall back to its static
IPv4 and/or IPv6 settings, or (2) indefinitely wait to acquire an address based on DHCP configuration
settings.
