Enable SNMP Monitoring
- Device > Setup > Operations
Simple Network Management Protocol (SNMP) is a standard protocol for monitoring the devices on your network. Select
Operationsto configure the firewall to use the SNMP version that your SNMP manager supports (SNMPv2c or SNMPv3). For a list of the MIBs that you must load into the SNMP manager so it can interpret the statistics it collects from the firewall, see Supported MIBs . To configure the server profile that enables the firewall to communicate with the SNMP trap destinations on your network, see Device > Server Profiles > SNMP Trap. The SNMP MIBs define all SNMP traps that the firewall generates. An SNMP trap identifies an event with a unique Object ID (OID) and the individual fields are defined as a variable binding (varbind) list. Click
SNMP Setupand specify the following settings to allow SNMP GET requests from your SNMP manager:
Specify the physical location of the firewall. When a log or trap is generated, this information allows you to identify (in an SNMP manager) the firewall that generated the notification.
Enter the name or email address of the person responsible for maintaining the firewall. This setting is reported in the standard system information MIB.
Use Specific Trap Definitions
This option is selected by default, which means the firewall uses a unique OID for each SNMP trap based on the event type. If you clear this option, every trap will have the same OID.
Select the SNMP version:
V3. Your selection controls the remaining fields that the dialog displays.
For SNMP V2c
SNMP Community String
Enter the community string, which identifies an SNMP
communityof SNMP managers and monitored devices and also serves as a password to authenticate the community members to each other when they exchange SNMP get (statistics request) and trap messages. The string can have up to 127 characters, accepts all characters, and is case-sensitive.
Don’t use the default community string
public. Because SNMP messages contain community strings in clear text, consider the security requirements of your network when defining community membership (administrator access).
For SNMP V3
Name / View
You can assign a group of one or more views to the user of an SNMP manager to control which MIB objects (statistics) the user can get from the firewall. Each view is a paired OID and bitwise mask: the OID specifies a MIB and the mask (in hexadecimal format) specifies which objects are accessible within (include matching) or outside (exclude matching) that MIB.
For example, if the
OIDis 126.96.36.199, the matching
Optionis set to
Maskis 0xf0, then the objects that the user requests must have OIDs that match the first four nodes (f = 1111) of 188.8.131.52. The objects don’t need to match the remaining nodes. In this example, 184.108.40.206.2 matches the mask and 220.127.116.11.2 doesn’t.
For each group of views, click
Add, enter a
Namefor the group, and then configure the following for each view you
Addto the group:
To provide access to all management information, use the top-level
OID18.104.22.168, set the
Maskto 0xf0, and set the matching
SNMP user accounts provide authentication, privacy, and access control when firewalls forward traps and SNMP managers get firewall statistics. For each user, click
Addand configure the following settings:
