Traps to an SNMP Manager
Simple Network Management Protocol (SNMP) traps can alert you to system events (failures or changes in hardware or software of Palo Alto Networks firewalls) or to threats (traffic that matches a firewall security rule) that require immediate attention.
- Enable the SNMP manager to interpret the traps it receives.
- Configure an SNMP Trap server profile.The profile defines how the firewall accesses the SNMP managers (trap servers). You can define up to four SNMP managers for each profile.Optionally, configure separate SNMP Trap server profiles for different log types, severity levels, and WildFire verdicts.
- Log in to the firewall web interface.
- Select.DeviceServer ProfilesSNMP Trap
- ClickAddand enter aNamefor the profile.
- If the firewall has more than one virtual system (vsys), select theLocation(vsys orShared) where this profile is available.
- Select the SNMPVersionand configure the authentication values as follows. For version details, see SNMP Support.
As a best practice, don’t use the default community stringpublic; it’s well known and therefore not secure.
- V2c—For each server, clickAddand enter the serverName, IP address (SNMP Manager), andCommunity String. The community string identifies a community of SNMP managers and monitored devices, and serves as a password to authenticate the community members to each other.
- V3—For each server, clickAddand enter the serverName, IP address (SNMP Manager), SNMPUseraccount (this must match a username defined in the SNMP manager),EngineIDused to uniquely identify the firewall (you can leave the field blank to use the firewall serial number), authentication password (Auth Password) used to authenticate to the server, and privacy password (Priv Password) used to encrypt SNMP messages to the server.
- ClickOKto save the server profile.
- Configure log forwarding.
- 4 For each log (trap) type and severity level, select theSNMP Trapserver profile.
- Monitor the traps in an SNMP manager.Refer to the documentation of your SNMP manager.When monitoring traps related to firewall interfaces, you must match the interface indexes in the SNMP manager with interface names in the firewall web interface. For details, see Firewall Interface Identifiers in SNMP Managers and NetFlow Collectors.
