SNMP

SNMP (Simple Network Management Protocol) gives access to XG Firewall information, for example, status of the firewall, service availability, CPU, memory, and disk usage. XG Firewall supports SNMPv3, SNMPv1 and SNMPv2c protocols.

  • To configure XG Firewall as an SNMP agent, select Enable SNMP agent and specify the settings.
  • To add an SNMPv1 and SNMPv2c community, select Add.
  • To add an SNMPv3 user, select Add. You can’t change the user name.

You can import or export an SNMP agent, community, or user configuration as a tar file from Backup and firmware > Import export.

SNMP agent

You can configure XG Firewall as an SNMP agent. It sends traps (alerts) of system-generated events to SNMP managers within its community and to specified SNMPv3 users. It also responds to the different SNMP queries triggered by the managers.

SNMPv1 and SNMPv2c community

You can configure SNMPv1 and SNMPv2c communities. XG Firewall communicates with the SNMP managers within its communities.

SNMPv3 user

You can add an SNMPv3 user and the authorized hosts. You can specify encryption and authentication settings to ensure confidentiality, message integrity, and validity of the user.

MIB and OIDs

The Management Information Base (MIB) contains the list of OIDs that XG Firewall supports. You need to add the MIB to your SNMP managers and authorized hosts. Download Sophos MIB.

OIDs (Object Identifiers) help you identify the events in traps. XG Firewall supports the following standard OIDs:

  • SNMPv2-MIB
  • IF-MIB [Counter32 and Counter64 supported]
  • SNMPv2-SMI
  • IP-MIB
  • IP-FORWARD-MIB
  • TCP-MIB
  • UDP-MIB
