- 1SNMPSimple Network Management Protocol
- 2I N F O Managing network devices manually is impractical.SNMP automates these tasks
- 3Managed devices are all the network devices around your organization that supports SNMP. ******************* Name 4 of those devicesrouters
switches
wireless access points
firewalls - 4_______ is a piece of software that runs on the managed device that supports SNMP and allows it to communicate with the SNMP service.SNMP agent
- 5I N F O SNMP Componentsthe SNMP agent is built into the network devices software
- 6_______ is the central system responsible for communicating with SNMP agents and managing the network.network management system
- 7I N F O: the network management system reaches out to the agents and requests whatever information administrators configured it retrieve.the network management system reaches out to the agents and requests whatever information administrators configured it retrieve.
- 8* information about network activity, device performance or other metrics. *When the network management system wants to retrieve info from managed device, it sends SNMP command called GetRequest * the managed device then sends the info back in SNMP response. *The network management system can also reconfigure devices
- 9EXAMPLE: administrator want to push out commands to all wireless access points, to broadcast a new SSID. ****************** The network management system sends commands using SNMP SetRequest, telling agent to set configuration on device. The agent sends back an SNMP response telling network management system whether configuration setting was successfully applied or not.
- 10Managed devices may initiate communication with network management system when they have unusual news to report. Agent sends SNMP trap to network management system *************** Example: Network link goes down on router router sends SNMP trap to network management system the management system responds by sending alert to administrators
- 11What version of SNMP is currently being used by administrators?SNMPv3
earlier versions have critical security flaws
