Switch-Initiated DNS packets go out through the VLAN having the
■
best route to the DNS server, even if a Management VLAN has been
configured.
The traceroute command output shows only IP addresses.
■
■ The DNS server address must be manually input. It is not be automat-
ically determined via DHCP.
■ Operation with IPv4 DNS servers has been verified and, while no
problems with servers supporting both IPv4 and IPv6 addresses are
expected, testing has not been performed with such servers. (IPv6
AAAA-style queries are not supported.)

Event Log Messages

Meaning
The switch does not have an IP address configured for the DNS
server.
The DNS server failed to respond or is unreachable. An incorrect
server IP address can produce this result.
The host name did not resolve to an IP address. Some reasons for
this occurring include:
• The host name was not found.
• The named domain was not found.
• The domain suffix was expected, but has not been configured. (If
the server's IP address has been configured in the switch but the
domain name has not been configured, then the host's fully
qualified domain name must be used.)
