You can control how your D230 base station accesses the web and the network. Control features include:
●
●
●
Enable Cisco Discovery Protocol (CDP)
Default DHCP Settings
When you initialize a network connection to a configuration server, your D230 extracts DHCP Option 160
from a DHCP offer by default. Your D230 also prioritizes DHCP Option 160 ahead of other options in the
ConfigURL
parameter using the following parameters and macros:
●
Option 160
is added to the
System Management > WAN Settings > DHCP Client
Settings::
ExtraOptions
parameter.
●
The
System Management > Auto Provisioning > ITSP Provisioning::
ConfigURL
parameter
includes the $
DHCPOPT160/$MAC.xml;$DHCPOPT160/$DM.xml;$DHCPOPT160;
tftp://$DHCPOPT66/$DM.xml;$DHCPOPT66/$DM.xml;$DHCPOPT66
macro string.
Don’t reconfigure this default setting.
DNS NAPTR Support
This feature enables DNS Name Authority Pointer (NAPTR) lookup for SIP proxy servers or outbound
proxies. Combining NAPTR with SRV records enables chaining multiple records. With NAPTR lookup, your
system can discover:
●
The hosts to access the SIP service for a given domain
●
The SIP transport, preference, and order of each host
●
The types of DNS records to use for each listed host (SRV or A record)
You can enable NAPTR for each ITSP Profile. If enabled, your system only attempts NAPTR lookup of the
domain name specified in the
OutboundProxy
parameter (if configured). Otherwise, your system uses the
ProxyServer
parameter (on the corresponding
ITSP Profile x > SIP
web page).
If NAPTR records aren’t available, your system doesn’t fall back to perform regular DNS SRV or DNS A
record lookup.
If a NAPTR record indicates to look up the host name as an SRV record, your system considers the host
name to be complete and doesn’t add a prefix when querying the DNS server for its SRV record, regardless
of the settings of the
X_DnsSrv
and
X_DnsSrvAutoPrefix
parameters.
