Chapter 24 Configuring SNMP
Configuring SNMP
The snmp-server host command specifies which hosts receive the notifications. The snmp-server
enab le trap command globally enables the mechanism for the specified notification (for traps and
informs). To enable a host to receive an inform, you must configure an snmp-server host informs
command for the host and globally enable informs by using the sn mp-se rver ena ble tr aps comman d.
To remove the specified host from receiving traps, use the no sn mp - server ho s t host global
configurat ion co mma nd. The no snmp-server host command with no keywords disables traps, but not
inform s, to the host . To disabl e informs , use the no sn m p- server h o st in form s g lo bal configur ation
command. T o disable a spec ific trap type , use the no snmp-server enable traps notification-types global
configurati on comm a nd.
