How to configure SNMPv3 on Dell EMC Networking N series switches.

Steps in configuring SNMPv3
 

1. Creating a SNMpv3 view.
2. Creating a SNMPv3 Group and associating with the View.
3. Creating a SNMPv3 user and associating with the Group

1.  Creating a SNMPv3 View
 

• A SNMPv3 view defines what we can see on the switch.
• A View defines what MIB family we have access to from the MIB Subtree.
• For Example, if we select the View as "system" from the MIB subtree, the user would be able to poll all the information which are below "system" OID.
• Similarly, if we need visibility to all the parameters, we can configure the view as "iso" from the MIB subtree.

Commands
 

Console#configure

console(config)#snmp-server view test_view internet included

2.  Creating a SNMPV3 Group
 

• The next step after creating a SNMPv3 view is to create a SNMPv3 group and associate it with the view that has been created.

console(config)#snmp-server group test_group v3 ‘noauth/auth/priv’ ‘read/write’ test_view

CLI Breakdown

 

auth       - Specifies authentication of a packet without encrypting it.

noauth  - Specifies no authentication of a packet.

priv        - Specifies authentication of a packet with encryption.

3.  Creating a SNMPV3 User

The next step after creating a SNMPv3 group is to create a SNMPv3 user and associate it with the group that has been created.

Commands

console(config)#snmp-server user test_user test_group auth-md5 password1 priv-3des password2
