CCNA 7.1.a: SNMPv2

Overview:

SNMPv2 improves upon the limitations in SNMPv1

 

Study Notes:

  • SNMPv2 improves upon SNMPv1 (SNMPv1 was criticized for poor security)
  • SNMPv2 includes these improvements
    • Performance - GetBulkRequest in addition to the iterative GetNextRequest
    • Security - party-based security system (obsoleted later due to complexity)
    • Confidentiality
    • Manager-to-manager communications
  • SNMPv2 still uses the less secure community-string
  • The SNMP managers able to access the agent should be defined by an ACL
  • Configuration

To enable polling:

Router(config)#snmp-server community public RO
Router(config)#snmp-server community private RW

 

To enable traps:

Router(config)#snmp-server enable traps <config>
Router(config)#snmp-server host <IP_address> version 2c public

 

To verify:

Router#show snmp group
Router#show snmp user
Router#show running-config | inc snmp
