BOF Configuration Command Reference
tertiary-dns
Syntax [no] tertiary-dns ip-address
Context bof
Description
This command configures the tertiary DNS server for DNS name resolution. The tertiary DNS server
is used only if the primary DNS server and the secondary DNS server do not respond.
DNS name resolution can be used when executing ping, traceroute, and service-ping, and also when
defining file URLs. DNS name resolution is not supported when DNS names are embedded in
configuration files.
The no form of the command removes the tertiary DNS server from the configuration.
Default
no tertiary-dns — No tertiary DNS server is configured.
Parameters
