xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch DHCPv6 Server DHCPv6 Server Global Settings This window is used to configure DHCPv6 server global settings, including specifying the range of IPv6 network addresses for the DHCPv6 pool. The IPv6 addresses in the range are free to be assigned to the DHCPv6 client. When the DHCPv6 server receives a request from the client, the server will automatically find an available pool to allocate an IPv6 address. This window also allows the user to specify the preferred-lifetime and valid-lifetime of IPv6 address within a DHCPv6 pool. The valid lifetime must be greater than or equal to the preferred lifetime. The beginning network address and ending network address must observer some rules: 1. The prefix of the beginning network address and ending network address must be consistent. Otherwise, the switch will display an error message. (e.g.: beginning network address is 2000::1/64, and the ending network address is 3000::100/64) 2. The beginning IPv6 address must be lower than or equal to the ending IPv6 address.(e.g.: the beginning network address is 2000::200/64, and the ending network address is 2000::100/64) 3. There must not be an intersection between the IPv6 address ranges of two pools. Otherwise, the Switch will display an error message. (e.g.: pool1: 2000::1/64 --- 2000::100/64, pool2: 2000::50/64 --- 2000::200/64) 4. The IPv6 network address cannot be either a link-local address or a multicast address. Otherwise, the Switch will display an error message. (e.g.:: pool1: FE80::1/64 --- FE80::100/64, pool2: FE80::200/64 --- FE80::300/64) To view this window, click L3 Features > DHCPv6 Server > DHCPv6 Server Global Settings, as shown below: Figure 4- 83.
