However, DNS does work for the Avaya Multiservice Switch’s Help
File HTTP server.
In order for the DNS client functionality to work, it must be enabled
on the switch and at least one name server IP address must be
specified.
The following DNS Client features are supported:
■
The DNS Client on the Avaya Multiservice switch is Stub
Resolver (i.e. it does not support Iteration). This means that
referral answers will be discarded. A Recursive DNS server
must be used if you intend on using FQDN for which the
configured DNS servers do not have resource records.
■
Up to six DNS name servers can be configured.
■
Up to six default DNS Domain Suffixes can be configured.
■
When DNS is enabled, DNS names can be used in place of IP
addresses for
ping , telnet , connect, traceroute and
copy tftp CLI commands.
■
The DNS client name can consist of up to 255 characters.
■
A single label within a DNS client name can consist of 63
characters.
Once enabled, you have the option of specifying a DNS suffix to add
to unqualified host names. If so, you need only type the host name,
in place of the IP address, without the suffix when entering
commands. The suffix will be appended to host names that have no
suffix.
