Installation and Operations Manual
IPv6 and Sentry Products
Server Technology is introducing IPv6 “dual stack” support to the PT22 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, a “stateful” auto-
configuration of DHCPv6.
 IPv6 Stateless Auto-Configured Address – (based on 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 – (based on 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 PT22 firmware supports the following network IPv6 and IPv4 protocols:
 DNS Ping
 FTP Server SNMPv1/2/3
 FTP Updates SNTP
 HTTP HTTPS
 SMTP
 Static IPv6 DHCPv6 (stateless and stateful)
 Syslog SNMPv1/2/3 Traps
 Telnet SSH
IPv4-Only Protocols:
The PT22 firmware supports the following network IPv4-only protocols:
 Cisco EnergyWise
 LDAP
 Load Shedding *
 RADIUS *
 TACACS+
* = may work with IPv6 addresses, but not tested.
