Pv6 RA Prefix - Add Row Screen

Prefix Type	Set the prefix delegation type used with this configuration. Options include Prefix, and prefix-from-provider. The default setting is Prefix. A prefix allows an administrator to associate a user defined name to an IPv6 prefix. A provider assigned prefix is made available from an Internet Service Provider (ISP) to automate the process of providing and informing the prefixes used.
Prefix or ID	Set the actual prefix or ID used with the IPv6 router advertisement.
Site Prefix	The site prefix is added into a router advertisement prefix. The site address prefix signifies the address is only on the local link.
Valid Lifetime Type	Set the lifetime for the prefix's validity. Options include External (fixed), decrementing, and infinite. If set to External (fixed), only the Valid Lifetime Sec setting is enabled to define the exact time interval for prefix validity. If set to decrementing,, use the lifetime date and time settings to refine the prefix expiry period. If set to infinite, no additional date or time settings are required for the prefix and the prefix will not expire. The default setting is External (fixed).
Valid Lifetime Sec	If the lifetime type is set to External (fixed), set the Seconds, Minutes, Hours, or Days values used to measure the prefix's expiration. 30 days, 0 hours, 0 minutes, and 0 seconds is the default lifetime.
Valid Lifetime Date	If the lifetime type is set to External (fixed), set the date in MM/DD/YYYY format for the expiration of the prefix.
Valid Lifetime Time	If the lifetime type is set to decrementing, set the time for the prefix's validity. Use the spinner controls to set the time in hours and minutes. Use the AM and PM radio buttons to set the appropriate hour.

If set to External (fixed), only the Preferred Lifetime Sec setting is enabled to define the exact time interval for prefix validity.
