Configuring the DNS template
A feature that uses the DNS template performs the DNS operation to determine the status of the
server. It is supported in both IPv4 and IPv6 networks.
In DNS template view, you can specify the address expected to be returned. If the returned IP
addresses include the expected address, the DNS server is valid and the operation succeeds.
Otherwise, the operation fails.
Create a mapping between the domain name and an address before you perform the DNS
operation. For information about configuring the DNS server, see Layer 3—IP Services
Configuration Guide.
To configure the DNS template:
1. Enter system view.
system-view
N/A
2.

resolution type.
resolve-type
{
A
|
AAAA
}
By default, the type is type A.
A type A query resolves a
domain name to a mapped IPv4
address, and a type AAAA
query to a mapped IPv6
address.
7. (Optional.) Specify the source
packets.
• IPv4 address:
source ip ip-address
• IPv6 address:
source ipv6 ipv6-address
By default, the packets take the
primary IP address of the output
interface as their source IP
address.
The source IP address must be
