Step Command 6. Configure the string to be filled in the data field of each data-fill string ICMP echo request. 7. Apply ICMP echo tests to the vpn-instance specified VPN. vpn-instance-name 8. Configure the source interface source interface for ICMP echo requests. interface-type interface-number 9. Configure the source IP address of ICMP echo requests. source ip ip-address 10. Configure the next hop IP address of ICMP echo requests. 11. Configure optional parameters. next-hop ip-address See "Configuring optional parameters for an NQA test group" Remarks Optional. By default, the string is the hexadecimal number 00010203040506070809. Optional. By default, ICMP echo tests apply to the public network. Optional. By default, no source interface is configured for probe packets. The requests take the IP address of the source interface as their source IP address when no source IP address is specified. The specified source interface must be up. Otherwise, no ICMP echo requests can be sent out. Optional. By default, no source IP address is configured. If you configure both the source ip command and the source interface command, the source ip command takes effect. The source IP address must be the IP address of a local interface. The local interface must be up. Otherwise, no ICMP echo requests can be sent out. Optional. By default, no next hop IP address is configured. Optional. Configuring DHCP tests DHCP tests of an NQA test group are used to test if a DHCP server is on the network, and the time for the DHCP server to respond to a client request and assign an IP address to the client. Before you start DHCP tests, configure the DHCP server. If the NQA (DHCP client) and the DHCP server are not in the same network segment, configure a DHCP relay. The interface that performs DHCP tests does not change its IP address. A DHCP test only simulates address allocation in DHCP. When a DHCP test completes, the NQA client sends a DHCP-RELEASE packet to release the obtained IP address. To configuring DHCP tests: 102

Step
Command
Remarks
6.
Configure the string to be
filled in the data field of each
ICMP echo request.
data-fill
string
Optional.
By default, the string is the hexadecimal
number 00010203040506070809.
7.
Apply ICMP echo tests to the
specified VPN.
vpn-instance
vpn-instance-name
Optional.
By default, ICMP echo tests apply to the
public network.
8.
Configure the source interface
for ICMP echo requests.
source interface
interface-type
interface-number
Optional.
By default, no source interface is
configured for probe packets.
The requests take the IP address of the
source interface as their source IP address
when no source IP address is specified.
The specified source interface must be up.
Otherwise, no ICMP echo requests can be
sent out.
9.
Configure the source IP
address of ICMP echo
requests.
source ip
ip-address
Optional.
By default, no source IP address is
configured.
If you configure both the
source ip
command and the
source interface
command, the
source ip
command takes
effect.
The source IP address must be the IP
address of a local interface. The local
interface must be up. Otherwise, no ICMP
echo requests can be sent out.
10.
Configure the next hop IP
address of ICMP echo
requests.
next-hop
ip-address
Optional.
By default, no next hop IP address is
configured.
11.
Configure optional
parameters.
See "
Configuring optional
parameters for an NQA
test group
"
Optional.
Configuring DHCP tests
DHCP tests of an NQA test group are used to test if a DHCP server is on the network, and the time for
the DHCP server to respond to a client request and assign an IP address to the client.
Before you start DHCP tests, configure the DHCP server. If the NQA (DHCP client) and the DHCP server
are not in the same network segment, configure a DHCP relay.
The interface that performs DHCP tests does not change its IP address. A DHCP test only simulates
address allocation in DHCP.
When a DHCP test completes, the NQA client sends a DHCP-RELEASE packet to release the obtained IP
address.
To configuring DHCP tests:
