Monitoring a network device

Let's look at the configuration of a Cisco Switch and PIX firewall device. You will learn how to secure the SNMP communication to the Cisco devices by using access lists and specifically defining the Cacti server as a trusted communication partner. The configuration will only deal with SNMPv2.

Configuring SNMP access on Cisco Switch

In order to configure and secure SNMP communication between the network device and your Cacti server, you will need to know its IP address or network range. For the following examples, let's assume that your Cacti server has the IP address 10.40.0.161 and the network range of your network management systems is 10.40.0.0/255.255.255.0. Look at the following access list and SNMP commands:
