    Privacy Protocol
    Defines the protocol that authenticates SNMPv3 privacy data.
    Access Control List
    Defines a space-separated list of IP addresses to which community usage is restricted. If the list is blank, the agent grants access to any system that uses the associated community name.
    Access Control Lists (ACLs) are only for communities that use SNMPv1.
    Access Control Lists (ACLs) are only for communities that use SNMPv1. See the hse Using section for information about defining SNMPv2c and SNMPv3 access lists.

    Encoding
    (Optional) Defines how to include the source address you defined in the
    Trap Source
    field of the

    pane in traps. This parameter is important if the trap source translates to an IPv6 address. Enter the encoding parameter in the three-digit format XYZ, assuming leading zeros.
    Default:
    000
    • X
      : Specifies whether to extend the four-byte IPv4 source address field (SNMPv1 traps only). 
      Values:
      0:
      The source address field includes only the 4-byte IPv4 source address field
      1:
      Extend the source address field to include 16-byte IPv6.
    • Y,Z:
      Specifies whether to include source information in the trap  varbind (Y) or UDP packet (Z; SNMPv1 traps only).
      Values:
      0
      : Do not modify the trap 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 the trap source.
    Default:
    Global Trap
    The Defined Trap Destinations table displays the trap destination.
