Creating NQA instances for link monitoring
Before you create NQA instances, make sure the VPN gateway and the core router support both SNMP
and NQA.
To monitor the link between the VPN gateway and the core router, create two NQA instances that both
use the basic indexes ICMP echo, UDP echo, and TCP connection. One instance monitors the
operations from the VPN gateway to the core router, and the other instance monitor the operations in
the opposite direction.
This section creates an NQA instance with the VPN gateway and the core router as the source and
destination devices, respectively. You can create the other NQA instance in the same way.
To create the NQA instance:
1.
Import the VPN gateway and the core router to the SHM:
a.
Click the Service tab.
b.
From the left navigation tree, click Service Health Manager > NQA Config > NQA Device.
The NQA Device page appears.
c.
Click Import.
The page for importing devices appears.
d.
Click Select Device, and select the VPN gateway and the core router.
e.
Click OK.
2.
Modify device configuration:
a.
Enable the NQA client and the NQA server on the VPN gateway and the core router,
respectively. For more information, see "Modifying the NQA server or client enabling state."
b.
Add a TCP listening service on the core router. For more information, see "Modifying TCP
listening services."
c.
Add a UDP listening service on the core router. For more information, see "Modifying UDP
listening services."
3.
Create an NQA type that includes the basic indexes ICMP echo, UDP echo, and TCP connection:
a.
Click the Service tab.
b.
From the left navigation tree, click Service Health Manager > NQA Config > NQA Type.
The NQA Type page appears.
c.
Click Add.
The page for adding an NQA type appears.
d.
In the Basic Information area, configure basic information for the NQA type:
−
Name—Enter Link for VPN Logon.
−
NQA Type Description—Enter monitor the link for VPN logon.
e.
In the Basic Index Information area, configure basic indexes for the NQA type:
−
Click Add.
−
Select Basic from the Index Group Name List in the Query area.
−
Select ICMP Echo, UDP Echo, and TCP Connection in the Basic Index Information area.
−
Click OK.
The added basic indexes are displayed in the basic index list. You can click the Modify
icon
to modify the settings for an index.
