6. SNMP

The simple network management protocol (SNMP) is a widely used protocol for checking what’s going on in your network. When you run the SBC, you probably also want to see statistics about the usage and get alarms when something goes wrong.

6.1 Setup of the SBC

The setup of SNMP on the SBC side is very simple. Essentially, you have to perform two steps:

Select the port on which the SNMP server should listen. By default, this would be port 161, but on a host that runs other SNMP services as well you might want to choose another port. This step must be done in the Port Binding web page.

Tell the SBC from which addresses to accept SNMP requests. In the Security Settings web page, you find the setting “Trusted IP Ad- dresses” in the SNMP section. Enter the IP addresses (separated by a space) or the IP address range here. The SBC will accept requests only from these addresses.

The IP addresses must be in the form dots-and-number nota- tion. The SBC does not perform a DNS resolution of the addresses. If you want to specify a range of addresses use the form Adr/Bits, where bits is a number indicating how many bits of the IP address should be consid- ered. For example, the string “192.168.2.0/24” would match addresses 192.168.2.0 until 192.168.2.255.

6.2 Setup of the Tools

The setup of the tools varies from tool to tool. Because the SBC does not offer a standard set of values (such as CPU temperature, disk
