Define Traps and Communities

SNMP settings define the communities that the agent uses and the destinations to which it sends traps.

Follow these steps:

1. Click the Resources tab, open the Configure pane, expand Policies, and click SystemEDGE.

   The Available Policies page appears.

2. Select the policy in the Available Policies table.

   The Summary page for the policy appears.

3. Click the Traps and Communities tab.

   The Communities page appears.

4. Select one of the following, click Action, and select Apply:
   • Include only Server-specific SNMP settings
   • Include Server-specific SNMP settings and all Default settings
   • Select Include Server-specific SNMP settings and selected Default settings

   The SNMP settings are updated and the community page in the Communities table displays the following:

   Name

   Specifies the name of the community string.

   Port

   Specifies the port of SNMP.

   SNMP Version

   Specifies the SNMP version that the community uses.

   Access Rights

   Specifies whether the community should have read-write or read-only permissions.

   Note: Add at least one read-only and one read-write community.

   Community/User

   Specifies the community name.

   Authentication Protocol

   Specifies the protocol to authenticate SNMPv3 data.

   Privacy Protocol

   Specifies the protocol to authenticate SNMPv3 data.

   Access Control List

   Specifies a space separated list of IP addresses to restrict community usage to those addresses only. If you leave the list blank, the agent grants access to any system that uses the associated community name. Access lists are only for communities that use SNMPv1.

   Note: For information about defining SNMPv2c and SNMPv3 access lists, see the SystemEDGE User Guide.

5. (Optional) Add, update, or delete other communities as necessary.
6. Click Save Policy.

   The policy is saved.

7. Click Trap Destinations.

   The Trap Destinations page appears.

8. Define a trap destination using the following controls and click Add:

   Trap Type

   Specifies the type of trap to send, depending on the SNMP version.

   Destination

   Specifies the IPv4 or IPv6 address to which to send traps.

   Port

   Specifies the UDP port to which to send traps.

   Community

   Specifies the community name sent with the traps.

   Encoding

   (Optional) Specifies how to include the source address you defined in the Trap Source field of the Control Settings pane in traps. This parameter is important if the trap source translates to an IPv6 address. Enter the encoding parameter in a three-digit format XYZ, assuming leading zeros.

   Default: 000

   X

   Controls extending the four byte IPv4 source address field (SNMPv1 traps only). Enter 0 to not extend the source address field to include the 16 byte IPv6 address, and enter 1 to extend the source address field.

   Y,Z

   Controls the inclusion of source information into the trap's varbind (Y) or UDP packet (Z; SNMPv1 traps only). Enter one of the following for these digits:

   0: Do not modify the trap's varbind or the outer UDP packet.

   1: Include the trap_source parameter as is in the varbind or packet (IPv4/IPv6 address or host name).

   2: Include the trap_source parameter preferably as an IPv4 address (then IPv6 address, then host name).

   3: Include the trap_source parameter preferably as an IPv6 address (then IPv4 address, then host name).

   4: Include the trap_source parameter preferably as a host name (then IPv4, then IPv6).

   5: Follow the preference for 2 and include the host name.

   6: Follow the preference for 3 and include the host name.

   7: Follow the preference for 1 and include the host name (if trap_source is an IPv6 address).

   Trap Source

   (Optional) Specifies the IPv4 or IPv6 address or the host name to use as trap source.

   Default: Global Trap

   The trap destination appears in the Defined Trap Destinations table.

9. (Optional) Add, update, or delete other trap destinations as necessary.
10. Click Save Policy.

    The policy is saved.
