Ethernet > Mod Config > TServ Options. SLIP BOOTP makes it possible for a computer
connecting to the MultiVoice Gateway over a SLIP connection to use the Bootstrap Protocol.
A MultiVoice Gateway can support BOOTP on only one connection. If both SLIP BOOTP and
BOOTP relay are enabled, you will receive an error message.
You can specify the IP address of one or two BOOTP servers, but you are not required to
specify a second BOOTP server.
If you specify two BOOTP servers, the MultiVoice Gateway that relays the BOOTP request
determines when each server is used. The order of the BOOTP servers in the BOOTP Relay
menu does not necessarily determine which server is tried first.
Local domain name
The Domain Name is used for DNS lookups. When the MultiVoice Gateway is given a host
name to look up, it tries various combinations, including the appending of the configured
domain name to the host name. The secondary domain name (Sec Domain Name) can specify
another domain that the MultiVoice Gateway can search. The MultiVoice Gateway searches
the secondary domain only after the domain specified by the Domain Name parameter.
DNS or WINS name servers
When the MultiVoice Gateway is informed about DNS (or WINS), Telnet and Rlogin users can
specify host names instead of IP addresses. If you configure a primary and secondary name
server, the secondary server is accessed only if the primary one is inaccessible.
DNS lists
DNS can return multiple addresses for a hostname in response to a DNS query, but it does not
include information about availability of those hosts. Users typically attempt to access the first
address in the list. If that host is unavailable, the user must try the next host, and so forth.
However, if the access attempt occurs automatically as part of immediate services, the physical
connection is torn down when the initial connection fails. To avoid tearing down physical links
when a host is unavailable, you can set the List Attempt parameter to Yes. The List Size
parameter specifies the maximum number of hosts listed (up to 35).
SNTP service
The MultiVoice Gateway can use Simple Network Time Protocol (SNTP)—RFC 1305 to set
and maintain its system time by communicating with an SNTP server. SNTP must be enabled
for the MultiVoice Gateway to communicate by means of that protocol. In addition, you must
specify your time zone as an offset from the Universal Time Coordination (UTC). UTC is in
the same time zone as Greenwich Mean Time (GMT). Specify the offset in hours, using a
24-hour clock. Because some time zones, such as Newfoundland, do not have an even hour
boundary, the offset includes four digits and is stated in half-hour increments. For example, in
Newfoundland the time is 1.5 hours ahead of UTC, which is represented as follows:
UTC +0130
For San Francisco, which is 8 hours ahead of UTC, the time would be:
UTC +0800
