update

DHCP Config commands

Controls the usage of the DDNS service

Supported in the following platforms:

•Mobility RFS4000 Controller

•Mobility RFS6000 Controller

•Mobility RFS7000 Controller

Syntax

update dns override

Parameters

Usage Guidelines

A DHCP client cannot perform updates for RR’s A, TXT and PTR. Use

update (dns) (override) to enable the internal DHCP Server to send DDNS updates for

resource records (RR’s) A, TXT and PTR. The DHCP Server can override the client, even if the client

is configured to perform the updates.

In the network pool of DHCP Server, FQDN is configured as the DDNS domain name. This is used

internally in DHCP packets between the controllers DHCP Server and the DNS server.

Example

RFController(config-dhcp)#update dns overr ide

RFController(config-dhcp)#

update dns override Controls the usage of the DDNS service

•dns override – Dynamic DNS Configuration

•override – Enable Dynamic Updates by

onboard DHCP Server
