Domain Name Service
Commands
These commands are used to configure Domain Naming System (DNS) services.
Entries can be manually configured in the DNS domain name to IP address
mapping table, default domain names configured, or one or more name servers
specified to use for domain name to address translation.
Note that domain name services will not be enabled until at least one name server
is specified with the
command and domain lookup is enabled with
the
command.
The switch performs both as a DNS client and a DNS server/proxy in the following
manner:
PC (DNS Client) <------> Switch (DNS client
1
, server/proxy
2
) <------> Server (another
server/proxy)
1
The switch acts as a DNS client when it intends to get an IP address for a host
name. In this case, it may add the domain suffix and then query name server(s).
2
Otherwise, the switch acts as a DNS server/proxy when an outside host (namely, a
DNS client) intends to get an IP address for a host name through the switch. In
this case, it will not add the domain suffix to query name server(s). That means
that the DNS client is reponsible for adding the domain suffix.
