With this menu, the SNMP V3 configuration can be modified.

Enable SNMP V3

This check box enables SNMPv3. SNMPv3 primarily adds security and remote configuration enhancements to SNMP.

When this option is enabled, the following additional fields become available:

- Username

- Authentication Password

- Authentication protocol

- Enable Privacy checkbox

Note: The Username and Authentication Password must be set for SNMPv3 to work, while the Private Password field is optional.
Note: The password must be at least 8 characters long.

Authentication protocol

Select the relevant Authentication protocol - MD5 or SHA. SHA is recommended because MD5 is unsecure and deprecated.

Enable Privacy

This checkbox can be used to set the Privacy Password and Privacy Protocol for SNMPv3.

Privacy protocol

Select the relevant Privacy protocol - AES or DES. AES is recommended because DES is deprecated.

Contact

This option allows the SNMP Contact string to be changed. For example, this could be e-mail address of the administrator of the LoadMaster.

SNMP Location

This option allows the SNMP location string to be changed.

Note: This field accepts the following characters:
a-z A-Z 0-9 _ . - ; , = : { } @ ( ) ? # % ^ + ~ !
Note: Do not enter a hashtag symbol (#) as the first character in the Location.

SNMP traps

When Enable SNMP Traps is selected and an IP address is specified in an SNMP trap sink text box, a trap is generated when an important event happens to a LoadMaster, Virtual Service, or Real Server. These are sent to the SNMP trap sinks. If a change is made, the LoadMaster waits for all changes to finish and then waits five seconds before reading it. At that point, all changes will have stabilized and SNMP traps can then be sent. If there are any state changes within the five second wait, the state changes are handled and then the wait is restarted.

Enable/Disable SNMP Traps

This toggle option enables and disables the sending of SNMP traps.

Note: SNMP traps are disabled by default.

Send SNMP traps from the shared address

Note: This check box is only visible when the LoadMaster is in HA mode.

By default, SNMP traps are sent using the IP address of the active HA unit as the source IP address. Enabling this option will send SNMP traps from the active HA unit using the shared IP address.

SNMP Trap Sink1

This option allows the user to specify a list of hosts to which a SNMPv1 trap will be sent when a trap is generated.

SNMP Trap Sink2

This option allows the user to specify a list of hosts to which a SNMPv2 trap will be sent when a trap is generated.
