Hi,
i opened a TAC.
here is the answer:
i use this url on the CPI to run SNMP WALK to device,
https://<IP-address-of-PI-server>/webacs/SnmpQueryAction.do
TAC - email
" Navigate your browser to the following location
https://<IP-address-of-PI-server>/webacs/SnmpQueryAction.do
You can select an existing device in PI or manually enter the details for an unknown/new device.
Enter system or .1.3.6.1.2.1.1 for OID & click WALK.
Note: you may need to login as the root user in the GUI."
and then we found out that the supported device has a different OID from the one we manged in the CPI:
we manged in the CPI:
N9K-C9372TX-E OID 1.3.6.1.4.1.9.12.3.1.3.1713
the supported device is:
Cisco Nexus 9372TX Switch OID:1.3.6.1.4.1.9.12.3.1.3.1627
be noted that the E is missing, i dont know why Cisco is taking time to add a device when the family are already supported??
hope that helped
