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
