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:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a DNS template and
enter DNS template view.
nqa template dns name N/A
3. (Optional.) Specify the
destination IPv4 or IPv6
address of DNS packets.
• IPv4 address:
destination ip ip-address
• IPv6 address:
destination ipv6 ipv6-address
By default, no destination IP
address is specified.
4. (Optional.) Configure the
destination port number for the
operation.
destination port port-number
By default, the destination port
number is 53.
5. Specify the domain name that
needs to be translated.
resolve-target domain-name
By default, no domain name is
specified.
6. Configure the domain name
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
IPv4 or IPv6 address for the
probe packets.
• IPv4 address:
source ip ip-address
• IPv6 address:
source ipv6 ipv6-address
By default, no source IP address
is specified.
The source IP address must be the
IP address of a local interface,
and the interface must be up.
Otherwise, no probe packets
can be sent out.
8. (Optional.) Configure the
source port for probe packets. source port port-number By default, no source port
number is configured.
9. (Optional.) Specify the IPv4 or
IPv6 address that is expected
to be returned.
• IPv4 address:
expect ip ip-address
• IPv6 address:
expect ipv6 ipv6-address
By default, no expected IP
address is specified.
Configuring the TCP template
A feature that uses the TCP template creates and starts the TCP operation to determine whether the NQA
client can establish a TCP connection to a specific interface on the server, and whether the service on the
interface of the server is available.
In TCP template view, you can specify the expected data to be returned. If you do not specify the
expected data, the TCP operation only tests whether the client can establish a TCP connection to the
server.
