HPE FlexFabric 5700 Series User Manual

113
The NQA client simulates the DHCP relay agent to forward DHCP requests for IP address acquisition
from the DHCP server. The interface that performs the DHCP operation does not change its IP
address. When the DHCP operation completes, the NQA client sends a packet to release the
obtained IP address.
To configure the DHCP operation:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Create an NQA operation
and enter NQA operation
view.
nqa entry
admin-name
operation-tag
By default, no NQA operation is
created.
3. Specify the DHCP type and
enter its view.
type dhcp
N/A
4. Specify the IP address of the
DHCP server as the
destination IP address of
DHCP packets.
destination ip
ip-address
By default, no destination IP
address is specified.
5. (Optional.) Specify the output
interface for DHCP packets.
out interface
interface-type
interface-number
By default, no output interface is
specified. The NQA client
determines the output interface
based on the routing table lookup.
6. (Optional.) Specify the
source IP address of DHCP
packets.
source ip
ip-address
By default, no source IP address
is specified for the request
packets. The requests take the IP
address of the output interface as
their source IP address.
The specified source IP address
must be the IP address of a local
interface, and the local interface
must be up. Otherwise, no probe
packets can be sent out.
The NQA client adds the source
IP address to the
giaddr
field in
DHCP requests to be sent to the
DHCP server. For more
information about the
giaddr
field,
see Layer 3—IP Services
Configuration Guide.
Configuring the DNS operation
The DNS operation measures the time for the NQA client to translate a domain name into an IP
address through a DNS server.
A DNS operation simulates domain name resolution and does not save the obtained DNS entry.
To configure the DNS operation:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Create an NQA operation
and enter NQA operation
view.
nqa entry
admin-name
operation-tag
By default, no NQA operation is
created.
3. Specify the DNS type and
enter its view.
type dns
