To configure a host receiver for SNMPv3 traps or informs in a global configuration mode, perform this
task:
Command
switch(config)# snmp-server host
ip-address {traps | informs} version 3
{auth | noauth | priv } username [udp_port
number]
The following example shows how toconfigure a host receiver for an SNMPv3 inform:
switch(config)# snmp-server host 192.0.2.1 informs version 3 auth NMS
The SNMP manager must know the user credentials (authKey/PrivKey) based on the SNMP engineID
Note
of the Cisco Nexus 5000 Series device to authenticate and decrypt the SNMPv3 messages.

Configuring the Notification Target User

You must configure a notification target user on the device to send SNMPv3 inform notifications to a
notification host receiver.
The Cisco Nexus 5000 Series switch uses the credentials of the notification target user to encrypt the
SNMPv3 inform notification messages to the configured notification host receiver.
For authenticating and decrypting the received INFORM PDU, The notification host receiver should
Note
have the same user credentials as configured in the Cisco Nexus 5000 Series switch to authenticate and
decrypt the informs.
Use the following command in global configuration mode to configure the notification target user:
Command
switch(config)# snmp-server user name
{md5 | sha} passphrase [auto] [priv
[aes-128] passphrase] [engineID id]
The following example shows how to configure a notification target user:
switch(config)# snmp-server user NMS auth sha abcd1234 priv abcdefgh enginID
00:00:00:63:00:01:00:a1:ac:15:10:03
