In this part (Part 3) I utilize SNMP v2 as a way of getting some visibility of what’s happening to device resources in the network. I will be using the application called Observium which is free to use for lab or learning purposes. The video shows how to set up the Palo Alto and Cisco devices so that they send SNMP information to the Observium application.

Palo Alto SNMP v2 Configuration

This post shows the configuration of the Palo Alto device configuration so that it can send information to the Observium SNMP application.

Create a SNMP trap server profile.

Device > Setup > Server Profiles > SNMP Trap

 

1-CreateTrap

Configure the device to allow the SNMP service.

Device > Setup > Operations > SNMP Setup

 

2-Operations

Configure the device to allow the Log Settings service to apply to the SNMP service.

Device > Log Settings > System

 

3-LogSetting

Configure a Management Profile to allow SNMP.

Network > Interface Management

 

4-ManagementProfile

Configure a Management Profile to allow SNMP.

Network > Ethernet > advanced > Management Profile > [SNMP]

 

5-ApplyManagementProfile

Cisco device configuration

This shows the configuration of Cisco devices so that they send SNMP v2 information to the Observium monitoring device. Sown are some some SNMP settings.

 

snmp-server community <password> <ro/rw>

snmp-server enable traps ?

snmp-server host <ip> version 2c <pswrd>

snmp-server location <yourLocation>

snmp-server chassis-id <yourID>

Observium Configuration

Observium is free to use in a personal learning lab. I tried the CentOSv7 but ran into issues. Ubuntu worked fine and without any issues.

1-Observium

Observium is easy and intuative to configure, below shows a screen of the dashboard with devices. Devices will show with a red background if communication problems exist.

I hope this has been of some help in configuring a SNMP to you.
