DNS CACHING
The IP phones have the ability to cache DNS requests as referenced in RFC1035 and RFC2181.
The phone caches DNS lookups according to the TTL field, so that the phone only performs
another lookup for an address when the TTL expires.
CONFIGURING NETWORK SETTINGS MANUALLY
If you disable DHCP on your phone, you need to configure the following network settings
manually:
•
IP Address
•
Subnet Mask
•
Gateway
•
Primary DNS
•
Secondary DNS
You can configure the network settings using the configuration files, the IP phone UI, or the
Mitel Web UI.
Errors Messages Display when Incorrect Network Settings Entered
The IP Phone UI AND the Mitel Web UI immediately notify the Administrator if an incorrect
value is being entered for the following network parameters in the IP Phone UI and the Mitel
Web UI:
•
A 0.0.0.0 entered as values for the
IP Address
,
Subnet Mask
and
Gateway
parameters
•
IP Address
and
Gateway
IP address parameter values entered exactly the same
•
Gateway
IP address and the
IP address
parameter values configured on the same subnet
If you configure the Gateway parameter and the IP Address parameter on the same subnet,
the following error message displays:
“Gateway IP address and the IP address parameter values configured
are not on the same subnet”.
For specific parameters you can set in the configuration files, see Appendix A, the section,
“Network Settings”
on
page A-9.
Note:
If you disable DHCP on the phone, the phone uses the TFTP protocol as the
default server protocol. If you want to specify a different protocol to use, see
“Configuration Server Protocol”
on
page 4-99
.
