Allowing management from only specified IP addresses
The Security sub-menu of the Configuration web page in the AP/BHM and SM/BHS includes the IP
Access Control parameter. Specify one, two, or three IP addresses that must be allowed to access
the management interface (by HTTP, SNMP, FTP or TFTP).
If the selection is:
IP Access Filtering Disabled, then management access is allowed from any IP address, even if
the Allowed Source IP 1 to 3 parameters are populated.
IP Access Filtering Enabled, and specify at least one address in the Allowed Source IP 1 to 3
parameter, then management access is limited to the specified address(es).
Configuring management IP by DHCP
The Configuration > IP web page of every radio contains a LAN1 Network Interface Configuration,
DHCP State parameter that, if enabled, causes the IP configuration (IP address, subnet mask, and
gateway IP address) to be obtained through DHCP instead of the values of those individual
parameters. The setting of this DHCP state parameter is also viewable, but is not settable, in the
Network Interface tab of the Home page.
In the SM/BHS, this parameter is settable
in the NAT tab of the Configuration web page, but only if NAT is enabled.
in the IP tab of the Configuration web page, but only if the Network Accessibility parameter in
the IP tab is set to Public.
DHCP option 81
The DHCP server can be used to register and update the pointer (PTR) and host (A) DNS resource
records on behalf of its DHCP-enabled clients.
The DHCP option 81 permits the client to provide its fully qualified domain name (FQDN) as well as
instructions to the DHCP server on how it would like the server to process DNS dynamic updates
(if any) on its behalf. The hostname is poplulated as SiteName.DomainName depending upon
following conditions:
If Sitename is default i.e. No Site Name , mac address will be used instead.
The SiteName should only be a-z | A-Z | 0-9 and period(.) and dash(-).
The domain name part should not start or end with dash (-).
The underscore or space in domain name part will be converted to dash(-), anything else apart
from valid characters will be skipped.
