When placed into IPv6 mode, the clock will use SLAAC (Stateless Address Auto-
Configuration) to create an IPv6 address based off of its MAC address and router
advertisements, as defined by RFC 4862. While in IPv6 mode, the clock will only
support IPv6 communication, and must be specifically configured. Refer to Appendix
A for information on the IP configuration commands.
•
DNS Servers must be specified as literal IPv6 addresses for the OnTime Clock to
perform name resolution.
•
Time Servers must be specified as either literal IPv6 addresses or hostnames with
a registered AAAA record.
•
Telnet con
nections can only be made via the OnTime Clock’s IPv6
address or
when connected directly to the PC via the link-local 169.254.0.100 IPv4 address.
•
When using a literal IPv6 address in the update command, the port number
MUST be specified. Netboot will function correctly with no additional
configuration.
Note that while in IPv6 mode, the clock will not register with a DNS or DHCP server. It is
strongly recommended that you record your clock’s MAC address when placing
it into IPv6
mode.
In order to make the management of your system as easy as possible, Novanex
recommends that you record the IP Address for each clock in a table similar to the one
below, particularly if you have elected to set a static IP Address.
