The issue is caused when SNMP has not been configured to allow access to the required MIBs.

Resolution

Below is a sample configuration that can be used on the Cisco Switch:

How to configure the SNMPV3 on Cisco Devices

Create a view:
```
snmp-server view <view-name> <mib-family-name>

<mib-family-name>
```
Includes iso, mib-2, system, interfaces, cisco, ciscoEnvMonTemperatureStatusEntry

Example:
```
snmp-server view cisco iso included
```

Group for the view:

snmp-server group V3GroupName v3 [auth/noauth] read V3ReadName write V3WriteName

Example: snmp-server group cisco v3 auth read cisco write cisco

Example: snmp-server group cisco v3 noauth read cisco write cisco

Create the user:

snmp-server user V3UserName V3GroupName v3 auth [sha/md5] [password]

Examples:

 snmp-server user cisco cisco v3 auth md5 cisco priv aes 128 cisco

 snmp-server user cisco1 cisco v3 auth sha cisco priv aes 128 cisco

UDT supports aes 128, aes 192, and 256 encryption.

Give access to the VLAN for the Group.
Without access list (if the switch is configured without access list):
```
snmp-server group cisco v3 auth context vlan- match prefix
```
With access list (if the switch is configured with access list):
```
snmp-server group cisco v3 auth context vlan- match prefix access <ACL number>
```
Do not enter the VLAN context in SNMPv3 Context while adding the node in UDT. See the following screen shots for your reference.
