    Simple Network Management Protocol allows network administrator to monitor the state of network devices. Devices use SNMP trap which are sent to the monitoring server which in turn can graph and analyze events and thresholds for CPU, memory, state of interfaces , routing protocols etc. and alerts Network Administrators. Second type of SNMP messages is SNMP GET and SNMP SET message. With GET message you can configure the network monitoring servers (SNMP Servers) to pool the devices and retrieve current information like current cpu utilization or interface load. SET message allows to configure particular features of the device from monitoring and management server. You can for example set the interface description by defining this in one place – on SNMP server.


    Router(config)#snmp-server host 10.10.10.1 public snmp cpu
    Router(config)#snmp-server host 10.10.10.2 public snmp memory
    Router(config)#snmp-server host 10.10.10.3 public snmp ospf eigrp bgp
    Router(config)#snmp-server enable traps
    Router(config)#snmp-server community public RO
    Router(config)#snmp-server community private RW

    In above listing the 10.10.10.1, .2 and .3 are IP addresses of SNMP servers, public is the community string that has to be common across devices and SNMP servers, memory is an example what to monitor specifically. To enable GET and SET messaging from servers you need to configure RO (for GET) and RW (for SET) commands along with communities.
