snmp-server

• 0 <WORD> – Sets a clear text SNMP community string
• 2 <WORD> – Sets an encrypted SNMP community string
  • <WORD> – Sets the SNMP community string

• ro – Assigns read-only access to the specified SNMP community (allows a remote device to retrieve information)
• rw – Assigns read and write access to the specified SNMP community (allows a remote device to modify settings)

In a managed network, the controller uses SNMP trap receivers to notify faults. SNMP traps are unsolicited notifications triggered by thresholds (or actions) on devices and are therefore an important fault management tool.

A SNMP trap receiver is the destination of SNMP messages (external to the controller). A trap is like a Syslog message, just over another protocol (SNMP). A trap is generated when a device consolidates event information and transmits the information to an external repository. The trap contains several standard items, such as the SNMP version, community, etc.

SNMP trap notifications exist for most controller operations, but not all are necessary for day-to-day operation.

• v1 – Uses SNMP version 1. This option is disabled by default.
• v2c – Uses SNMP version 2c. This option is disabled by default.
• v3 – Uses SNMP version 3. This option is enabled by default.

• <1-65535> – Optional. Specify a value from 1 - 65535. The default port is 162.

• all – Enables SNMP manager version v1, v2 and v3
• v1 – Enables SNMP manager version v1 only. SNMPv1 uses a simple password (“community string”). Data is unencrypted (clear text). Consequently it provides limited security, and should be used only inside LANs behind firewalls, not in WANs.
• v2 – Enables SNMP manager version v2 only. SNMPv2 provides device management using a hierarchical set of variables. SNMPv2 uses Get, GetNext, and Set operations for data management. SNMPv2 is enabled by default.
• v3 – Enables SNMP manager version v3 only. SNMPv3 adds security and remote configuration capabilities to previous versions. The SNMPv3 architecture introduces the User-based Security Model (USM) for message security and the View-based Access Control Model (VACM) for access control. The architecture supports the concurrent use of different security, access control and message processing techniques. SNMPv3 is enabled by default.

• <64-1024> – Optional. Specify a value from 64 - 1024. The default is 128.

• <2-720> – Optional. Specify a value from 2 - 720 seconds. The default is 240 seconds.

• 0 – If this option is selected, an empty string is returned for the SNMP request for security configuration information. Security configuration information consists of:
• Passwords
• Keys
• Shared secrets

The default setting is 0.

• 1 – Suppresses the display of the policy, IP ACL, passwords, keys and shared secrets. If this option is selected, in addition to suppression from ‘Level 0', an empty string is returned for a SNMP request on following items:
• Management policies
• IP ACL
• Tables containing user names and community strings

• snmpmanager – Sets user as a SNMP manager
• snmpoperator – Sets user as a SNMP operator
• snmptrap – Sets user as a SNMP trap user

• auth – Uses an authentication protocol
  • md5 – Uses HMAC-MD5 algorithm for authentication

• 0 <PASSWORD> – Configures clear text password
• 2 <PASSWORD> – Configures encrypted password
  • <PASSWORD> – Specifies a password for authentication and privacy protocols

• snmpmanager – Sets user as a SNMP manager
• snmpoperator – Sets user as a SNMP operator
• snmptrap – Sets user as a SNMP trap user

• encrypted – Uses encrypted privacy protocol

• auth – Sets authentication parameters
  • md5 – Uses HMAC-MD5 algorithm for authentication

• des – Uses CBC-DES for privacy

  After specifying the privacy protocol, specify the authentication mode.

• auth – Sets user authentication parameters
  • md5 – Uses HMAC-MD5 algorithm for authentication

Configures password using one of the following options:

• 0 <PASSWORD> – Configures a clear text password
• 2 <PASSWORD> – Configures an encrypted password
  • <PASSWORD> – Specifies a password for authentication and privacy protocols
