DHCP IPv6 is similar to DHCP IPv4, however there is: • no default gateway option defined because a host learns the gateway using router advertisement messages • there is no WINS servers because it is obsolete. For more information about DHCP IPv6, see RFC 3315. |
Addressing mode section of New Interface page for DHCP information | ||
Status | Displays DHCP status messages as the interface connects to the DHCP server and gets addressing information. Select Status to refresh the addressing mode status message. Status can be one of: • initializing - No activity. • connecting - interface attempts to connect to the DHCP server. • connected - interface retrieves an IP address, netmask, and other settings from the DHCP server. • failed - interface was unable to retrieve an IP address and other settings from the DHCP server. | |
Obtained IP/Netmask | The IP address and netmask leased from the DHCP server. Only displayed if Status is connected. | |
Renew | Select to renew the DHCP license for this interface. Only displayed if Status is connected. | |
Expiry Date | The time and date when the leased IP address and netmask is no longer valid for the interface. The IP address is returned to the pool to be allocated to the next user request for an IP address. Only displayed if Status is connected. | |
Default Gateway | The IP address of the gateway defined by the DHCP server. Only displayed if Status is connected, and if Receive default gateway from server is selected. | |
Distance | Enter the administrative distance for the default gateway retrieved from the DHCP server. The administrative distance, an integer from 1‑255, specifies the relative priority of a route when there are multiple routes to the same destination. A lower administrative distance indicates a more preferred route. | |
Retrieve default gateway from server | Enable to retrieve a default gateway IP address from the DHCP server. The default gateway is added to the static routing table. | |
Override internal DNS | Enable to use the DNS addresses retrieved from the DHCP server instead of the DNS server IP addresses on the DNS page. When VDOMs are enabled, you can override the internal DNS only on the management VDOM. | |
