Canopy devices allow for configuration of a preferred and alternate DNS server IP address either
automatically or manually. Devices must set DNS server IP address manually when DHCP is
disabled for the management interface of the device. DNS servers may be configured
automatically from the DHCP response when DHCP is enabled for the management interface of
the device. Optionally devices may be configured to set the DNS server IP address manually when
DHCP is enabled for the management interface. The default DNS IP addresses are 0.0.0.0 when
configured manually.
Preferred DNS Server
The first address used for DNS resolution.
Alternate DNS Server
Upon failure to reach the Preferred DNS Server, the Alternate DNS Server is used.
Domain Name
The operator’s management domain name may be configured for DNS. The domain name
configuration can be used for configuration of the servers in the operator’s network. The default
domain name is example.com, and is only used if configured as such.
LAN2 Network Interface Configuration (RF Private Interface),
IP Address
You should not change this parameter from the default AP private IP address of 192.168.101.1. A
/24 CIDR subnet is used to communicate with each of the SMs that are registered. The AP uses a
combination of the private IP and the LUID (logical unit ID) of the SM.
For example, if an SM is the first to register in an AP, and another SM registers later, then the AP
whose Private IP address is 192.168.101.1 uses the following SM Private IP addresses to
communicate to each:
SM LUID Private IP
First SM registered 2 192.168.101.2
Second SM registered 3 192.168.101.3
NOTE:
Where space is limited for subnet allocation, be advised that an SM need not
have an operator-assigned IP address. The SM is directly accessible without an
LUID if either the SM Color Code parameter is set to 0 or the AP has a direct
Ethernet connection to the SM.
