Access Points provide DDNS support by adding the host name (option 12) in DHCP Client
messages. The DHCP server uses this option to dynamically update the DNS server.
Access Point System Naming Convention
The Access Point's system name is used as its host name. To prevent Access Points that have
default configurations from registering similar host names in DNS, the default system name of
the Access Point is uniquely generated. Access Points generate unique system names by
appending the last 3 bytes of the Access Point's MAC address to the default system name.
The system name must be compliant with the encoding rules for host name per DNS RFC 1123.
The DNS host name encoding rules are:
Characters must be alphanumeric or hyphen.
●
The name must not start or end with a hyphen.
●
The name must not start with a digit.
●
The number of characters must be 63 or less. (Currently the system name length is limited
●
to 32 bytes).
Image upgrades can cause the system to boot with an older system name format that is not
DNS compliant. To prevent problems with dynamic DNS after an image upgrade, the system
name is automatically converted to a DNS-compliant system name.
The rules of conversion of older system names are:
If the length is greater than 63 then the string is truncated. (This will not happen since the
●
system name is anyway limited to 31 bytes)
All invalid characters at the beginning or end of the string are replaced with the character
●
X.
All other invalid characters are replaced with hyphens.
●
Network Configuration
To configure network parameters, use the Network tab.This tab consists of three subtabs:
IP Configuration
●
DHCP Server Configuration
●
Link Integrity Configuration
●
