Steps in configuring SNMPv3
- Creating a SNMpv3 view.
- Creating a SNMPv3 Group and associating with the View.
- 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
CLI Breakdown
| Parameter | Description |
| test_view | name we create locally on the switch for the SNMP view |
| internet | MIB family which we select from the OID subtree. |
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
| Parameter | Description |
| test_group | name we create locally on the switch for the SNMP group |
| noauth/auth/priv | authentication type |
| test_view | Associating the SNMPV3 group with the SNMPV3 view created earlier. |
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
CLI Breakdown
| Parameter | Description |
| test_user | name we create locally on the switch for the SNMP user |
| test_group | Associating the SNMPV3 user with the SNMPV3 group created earlier |
| Auth | Authentication password |
| Priv | Encryption key |
Configuration Example
Console# configure
Console(config) snmp-server view test_view internet included
Console(config) snmp-server group test_group v3 priv read test_view
Console(config) snmp-server user test_user test_group auth-md5 password1 priv-3des password2
Switch Running Configuration output
snmp-server view "test_view" internet included
snmp-server group "test_group" v3 priv read "test_view"
snmp-server user "test_user" test_group auth-md5-key 240826d65a17fe9d8826630917f60b0f priv-3des-key 240826d65a17fe9d8826630917f60b0f400dd0592395032de9b2ad0759c017e9
