Prerequisites for Onboarding Devices
Before adding devices, you must ensure that the devices themselves are configured to collect and transmit telemetry data properly and communicate successfully with Cisco Crosswork Optimization Engine. The following sections provide sample configurations for a variety of communications options. Use them as a guide to configuring the devices you plan to manage using Cisco Crosswork Optimization Engine.
Pre-Onboarding SNMP v2 Device Configuration
 Note |
Only SNMPv2 and SNMPv3 (NoAuth/NoPriv) traps are supported. |
The following commands provide a sample pre-onboarding device configuration that sets the correct SNMPv2 and NETCONF configuration, and SSH and Telnet rate limits. The NETCONF setting is only needed if the device is MDT-capable.
logging console debugging

telnet vrf default ipv4 server max-servers 100

Pre-Onboarding SNMPv3 Device Configuration
If you want to enable SNMPv3 data collection, repeat the SNMPv2 configuration commands in the previous section, and add the following commands:
snmp-server group grpauthpriv v3 priv notify v1default
snmp-server user <user-ID> grpauthpriv v3 auth md5 <password> priv aes 128 <password>
).
