How to Discover WAN Monitoring?

WAN monitoring refers to the process of supervising and managing the availability and health of the WAN link network. It is often crucial for businesses relying heavily on WAN connectivity that their network is available effeciently round the clock.

This is where the Motadaata NMS WAN monitoring feature, helps to monitor the availability of the WAN links, RTT (Round Trip Time), and the network traffic details of your organization. Also, you can view the WAN availability reports on the dasboard and check the performance based on which you can take the necessary measures.

Read on to know the steps involved in monitoring the WAN links.

Prerequisites

• The SNMP Walk response of the following devices should be available from the Motdata NMS backend server:

  • Router’s IP Address
  • Internet Service Provider’s (ISP) IP Address

  You can check the SNMP walk response using the following command:

  Syntax for v2: snmpwalk -v2c -c [communutiy_name][Router or ISP’s IP Address]

  Example: snmpwalk -v2c -c public 10.13.15.90

  Syntax for v3: snmpwalk -v3 -l (noAuthNoPriv|authNoPriv|authPriv) -u (username) [-a (MD5|SHA)][-A (authphrase)] [-x DES][-X (privaphrase)] (ipaddress)[:(dest_port)][oid]

  Example: snmpwalk -v3 -u site1md5aes -l authPriv -a MD5 -A site1md5aes -x AES -X site1md5aes 192.168.10.11

Supported Devices

• CISCO (IP SLA)
• Juniper (RPM)

Architecture

In the above figure, the WAN link between the router and the ISP can be monitored using the below steps.

1. Create the credentials for network discovery.
2. Create and perform the Network Discovery of the router’s interface 10.10.10.1.
3. Provision the interface.
4. Create the credentials for WAN monitoring.
5. Create a WAN Monitoring profile of the link with source IP as 10.10.10.1 and destination IP as 10.10.10.2.
6. Provision the WAN link.
7. Once done, the link will be configured and monitored henceforth.

Procedure

To discover the WAN Link monitor, follow the below steps:

1. Log in to the NMS portal.

Create Network Credential Profile

2. Navigate to Admin > Discovery Settings > Network Credential Profiles page and click +New.

Enter the below details:

Fields	Description
Credential Profile Name	Enter the name of the credential profile.
Device Type	Select the type for which you want to create the credential. Here, Router is selected.
Version	Select the version number of the SNMP device. The options are: • V1 • V2c • V3
Community	Enter the community name as per the version selected. It is the unique string similar to the username used for handshaking. Motadata will send this string in request and device with same string responds back.
Security Level	Select the type of security based on the credentials used. • No Authentication No Privacy: Fill only ‘Security User Name’. • Authentication No Privacy: Fill ‘Security User Name’ and ‘Authentication Password’. • Authentication Privacy: Fill ‘Security User Name’, ‘Authentication Password’, and ‘Private Password’.
Authentication Protocol	Select the protocol used in the SNMP device for authentication.
Privacy Protocol	Select the protocol used in the SNMP device for privacy.
Security User Name	Provide the username to access the SNMP device.
Authentication Password	Provide encryption password to access SNMP device (if applicable).
Private Password	Provide private password to access SNMP device (if applicable).
Departments	Select the department whose users can view and use this credential profile.

3. Once done, click Create. Next, create the network discovery profile.

Create Network Discovery Profile

4. Navigate to Admin > Discovery Settings > Network Discovery Profiles page and click +New.

Enter the below details:

Fields	Description
Name	Enter the name of the network discovery profile.
IP/Host	Enter the IP or hostname of the device that you want to discover. For example, 10.10.10.1 is used.
RPE	Select the RPE from which you want to discover and poll monitors. By default, ‘Master RPE’ is selected.
Device Types	Select the device types for which you want to create the discovery profile.
Credential Profiles	Select the credentials that will be used for discovery. You can also create a new one using the +New button.
Tags	Select the tags used to categorize and group profiles.
Discovery Parameters	Default port is visible at bottom. You can change the port by editing the section. ‘Monitor unused port’ will discover the unused ports also. To discover only used ports, edit the section and select yes.

5. Once the details are filled in, click Create, and run the discovery. The following screen will appear.

6. Click the “View Result” button or the link “Click Here” in the Discovery Notification. The following popup appears.

7. Provision the discovered device. To provision,

   a. Click the “View Result” button on the list page (Step 5).

   b. Select the “Host” IP Address.

   c. Click the “Provision Objects” button.

Once the network device is provisioned, create a WAN credential profile.
