Reference12r2:IP6/ETH/DHCP6
The DHCP function can either be disabled or operated in DHCP Client, DHCP Inform or in DHCP Server mode. The DHCP function of the Ethernet interface has four operating modes:
Disabled: | The IP-Adresse and other parameters are configured manually. | ||||||||
Inform: | The IP-Adresse are configured manually. Additional Configurations like DNS, NTP e.g. are received via a DHCP lease. | ||||||||
Server: | The IP parameters are configured manually in DHCP Server mode. The DHCP server is on and should be configured accordingly as described in "IP6/ETH/Server".
| ||||||||
Client: | In DHCP Client mode, the device receives its IP configuration from a DHCP server to whose network the device is connected.
Running an innovaphone DHCP server when there is already oneIt might be pretty convenient to run an innovaphone DHCP server in addition to an existing one in a network. This simplifies deployment of vendor specific configuration options. To make sure such leases are only sent to innovaphone (and explicitly reserved) clients, you would turn on Serve Vendor Clients Only on the innovaphone DHCP server. This will not send offers to other requesters and will include a server identifier within any offer sent. By default, an innovaphone DHCP client will wait for a lease with matching Server Identifier for 8 seconds. Also by default, the vendor identifier is empty. As a result, to have clients with factory settings run with the innovaphone's DHCP offer, you should turn on Serve Vendor Clients Only mode on the server and leave the Server Identifier empty. If so, an out-of-the-box innovaphone DHCP client will prefer the offer sent by the innovaphone server (provided it appears 8 seconds after the first offer the latest). |
