Working with the M111
DNS configuration
If the M111 is configured as a DHCP client, the following options are displayed:

Server 1
Specify the IP address of the first DNS server that the M111 will use.
Server 2
Specify the IP address of the second DNS server that the M111 will use.
Server 3
Specify the IP address of the third DNS server that the M111 will use.
DNS advanced settingsDNS cacheEnables the DNS cache. Once a host name has been successfully resolved to an IP address by a remote DNS server, it is stored in the cache. This speeds up network performance, as the remote DNS server now does not have to be queried for subsequent requests for this host.
The entry stays in the cache until:
An error occurs when connecting to the remote host
The time to live (TTL) of the DNS request expires
The M111 is restarted.
DNS switch on server failureThis setting controls how the M111 switches between the primary and secondary DNS servers.
