Parameters Description

ULA Mode Indicates the unique local IPv6 address (ULA) mode. A ULA address starts with a prefix fd. Similar to a reserved IPv4

address, the reserved IPv6 address is used for private purpose. This is to ensure protocol consistency.

This parameter can be set to Manual, Automatic, or Prohibit. Prohibit is recommended.

Prohibit: This function is disabled.

Automatic: The system automatically assigns addresses.

Manual: The address needs to be entered. If this option is selected, Prefix, Prefix Length, Preferred

Lifetime, and Valid Lifetime also need to be set.

Prefix Indicates the network address space. IPv6 uses a prefix to indicate the network address space. For example,

2001:db8:e000::/48 indicates an address space with a 48-bit prefix.

Prefix Length Indicates the prefix length, which is a decimal value. It specifies the number of left-most bits used to form a prefix in

an address. The address prefix is expressed in the "IPv6 address/prefix length" format. For example,

2001:db8:e000::/48 indicates an address space with a 48-bit prefix.

Preferred Lifetime Indicates the period of time for which a valid address is in the preferred state. When the preferred lifetime expires, the

address becomes out of date.

Valid Lifetime Indicates the period of time for which an address is valid. The valid lifetime must be longer than the preferred lifetime.

When the valid lifetime expires, the address becomes invalid.
