address of DNS packets.
•
IPv6
address:
destination ipv6
ipv6-address
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 performs the TCP operation to test the following items:
•
Whether the NQA client can establish a TCP connection to a specific port on the server.
•
Whether the requested service is available on the server.
In TCP template view, you can specify the expected data to be returned. If you do not specify the
expected data, the TCP operation tests only whether the client can establish a TCP connection to the
server.
The TCP operation requires both the NQA server and the NQA client. Before you perform a TCP
operation, configure a TCP listening service on the NQA server. For more information about the TCP
listening service configuration, see "
To configure the TCP template:

address of the operation.
•
