Hi

When setting up a monitoring system it usually uses SNMP to gather information. When there is an error the SNMP agent is suppose to send a trap to the SMNP manager/monitoring system, but i have one question here.

If i setup a monitoring system to monitor a router, a switch and lets say, 10 servers. Is the snmp agent already installed on the router, switch and the 10 servers (i guess it has to be started on the servers) so it can send traps? ..I mean, do i need to install an snmp agent on the routers and switch or just the servers?

for windows servers, cisco router/switches you have to install and activate the trap destination first.

HTH.

you wouldn't *install* an agent on a bit of networking kit, but you obviously need to configure it.. how else is it meant to know where to send traps to? note that snmp polling and snmp traps are largely seperate. we poll our devices with snmp but don't use any traps at all, prefering syslog instead.

yup of course - i mean "install" (from add remove program windows component|networking service) & configure the snmp agent, community, traps on windows,
configure and activate the snmp community and traps on ciscos.
syslog is OK - but if you activate logging for the ACL on cisco - you'll get a very busy machine.
