Adding or removing a trap receiver
Under Trap Receivers, these configuration options are available:
Add a New Trap Receiver
Displays the controls to add a new trap receiver.
Receiver
Specifies the destination IPv4 address or hostname for the SNMP trap.
Destination Port
Specifies the destination port.
Receiver Type
Indicates SNMP v1, v2c, or v3 (user-based security model).
Remote User
(Appears only when you select v3.) Specifies a remote username.
Authentication
(Appears only when you select v3.) Indicates either Supply a Password or Supply a Key to use while authenticating users.
Authentication Protocol
(Appears only when you select v3.) Specifies an authentication method from the drop-down list:
• MD5 specifies the Message-Digest 5 algorithm, a widely used cryptographic hash function with a 128-bit hash value. This is the default value.
• SHA specifies the Secure Hash Algorithm, a set of related cryptographic hash functions. SHA is considered to be the successor to MD5.
Password/Password Confirm
(Appears only when you select v3 and Supply a Password.) Specifies a password. The password must have a minimum of eight characters. Confirm the password in the Password Confirm text box.
Security Level
(Appears only when you select v3.) Determines whether a single atomic message exchange is authenticated. Select one of these levels from the drop-down list:
• No Auth doesn’t authenticate packets and doesn’t use privacy. This is the default setting.
• Auth authenticates packets but doesn’t use privacy.
• AuthPriv authenticates packets using AES 128 and DES to encrypt messages for privacy.
A security level applies to a group, not to an individual user.
Privacy Protocol
(Appears only when you select v3 and AuthPriv.) Indicates either the AES or DES protocol from the drop-down list. AES uses the AES128 algorithm.
Privacy
(Appears only when you select v3 and AuthPriv.) Indicates Same as Authentication Key, Supply a Password, or Supply a Key to use while authenticating users. The default setting is Same as Authentication Key.
Privacy Password
(Appears only when you select v3 and Supply a Password.) Specifies a password. The password must have a minimum of eight characters. Confirm the password in the Privacy Password Confirm text box.
MD5/SHA Key
(Appears only when you select v3 and Authentication as Supply a Key.) Specifies a unique authentication key. The key is either a 32-hexadecimal digit MD5 or a 40-hexadecimal digit SHA digest created using md5sum or sha1sum.
Privacy MD5/SHA Key
(Appears only when you select v3 and Privacy as Supply a Key.) Specifies the privacy authentication key. The key is either a 32-hexadecimal digit MD5 or a 40-hexadecimal digit SHA digest created using md5sum or sha1sum.
Community
(For v1 or v2 trap receivers.) Specifies the SNMP community name. For example, public or private v3 trap receivers need a remote user with an authentication protocol, a password, and a security level.
Enable Receiver
Enables the new trap receiver. Clear the check box to disable the receiver.
Add
Adds a new trap receiver to the list.
