Snmp-server host

As explained in Acing the CCNA Exam: Volume 2 Advanced Networking and Security

snmp-server host is a Cisco IOS global configuration command that specifies an SNMP notification destination, protocol version, and community string.

snmp-server host is a Cisco IOS global configuration command that identifies an NMS destination for SNMP Trap and Inform messages. Its community string authenticates notifications sent to that NMS; it does not define the community strings used to authorize Get or Set requests. section 6.3.1

Configure an SNMPv2c notification destination

R1(config)# snmp-server enable traps R1(config)# snmp-server host 192.168.1.10 version 2c password789 The first command enables Trap messages; the second sends SNMPv2c Traps to 192.168.1.10 with password789. The notification string may differ from the RO and RW strings configured with snmp-server community. section 6.3.1

How Acing the CCNA Exam: Volume 2 Advanced Networking and Security covers it

How deep it goes
Explains syntax, notification behavior, community-string separation, and the prerequisite trap-enablement command.
Examples
Uses 192.168.1.10 as the NMS, version 2c, and password789 as the outgoing community string.
What it assumes
Requires understanding SNMP community strings and enabling Trap messages separately with snmp-server enable traps.
What you can do after
Operate/configure Cisco IOS to send SNMPv2c Traps to a specified NMS with a chosen notification community string.
How it connects
Connects SNMPv2c notifications with Traps, Informs, community strings, NMS devices, and snmp-server enable traps.
