The following procedure describes how to quickly configure network quality probing.
To configure network quality probing:
1. Configure the "sender termination" side:
a. Bind a WAN interface to the NQM service:
(config-system) bind GigabitEthernet 0/0 nqm
Note: The chosen
packets are planned to flow bi-directionally and binding is necessary to create
the corresponding static NAT rules. If the NQM session is planned to flow
within the LAN then no binding is needed and this step can be skipped.
b. Configure a row in the Probing table:
(config-system)# nqm probing-table 0
(probing-table-0)# set probe-name voip_probe_1 ;
identifies this line
(probing-table-0)# set start-time now ; starting time of
this probe
(probing-table-0)# exit ; activates the probe
c. Configure a row in the Sender table to define a sender termination:
(config-system)# nqm sender-table 0
(sender-table-0)# set sender-name
main_office_voip_checker_1 ; identifies specific sender
(sender-table-0)# set target-ip 10.4.3.98 ; IP address
of responder termination
(sender-table-0)# set target-port 3900 ; listening port
number at responder termination
Note: A responder termination defined by the pair <target IP address, target port>
can be defined only once for a single sender line; multipile senders can’t be
defined to send packets to the same responder termination.
(sender-table-0)# set probe-name voip_probe_1 ; name
of probing row previously configured to be used by this
sender
Note: A single row in the Probing table may be shared by several senders, thereby
sharing and simplifying common attributes.
(sender-table-0)# set source-interface-name NQM_WAN ;
name of network interface to send packets from
Note: If you want to output packets to the WAN interface, simply set NQM_WAN as
the source interface name; otherwise, set the interface name to a specific
interface name listed in the network interface table.
(sender-table-0)# exit ; activates the sender line
