SNMPv3 credentials

To add a new set of SNMPv3 protocol credentials:

1. From the main menu of the WhatsConnected console, select Configure > Protocol Settings/Credentials. The Protocol Settings/Credentials dialog appears.
2. Click New.
3. Select SNMPv3, then click OK. The protocol properties dialog appears.
4. Enter a Name for the set of SNMPv3 credentials.
5. Enter the Username that is configured for the SNMP agent. This username is included in every SNMP packet in the authentication header. An SNMP device, upon reception of a packet, uses this username to look for configured authentication and encryption parameters and applies them to the received message.
6. Optionally, enter the Context needed to identify specific SNMP instances on your network.
7. If required, select the Protocol used for Authentication. Additionally, enter the Password used for authentication.
8. If supported, select the Protocol used for Encryption. Additionally, enter the Password used for encryption.
9. Increase or decrease the SNMP Timeout. This setting is dependent on the latency and load on your network devices. Longer timeouts can cause discovery to slow down. However, if the network is experiencing a lot of network traffic, a longer timeout is recommended. A default of 1000 milliseconds is recommended for small to medium size networks.

   Note: If you are discovering across a WAN link, allow for a longer timeout.

10. Increase or decrease the SNMP Retry count. This setting is dependent on the latency and load on your network devices. More retries allow for SNMP failures or heavy network loads. However, more retries slow down the discovery process. One or two retries is recommended for small to medium size networks.

    Note: If you are discovering across a WAN link, increase the number of retries.

11. Click OK to save the protocol changes.
