A network engineer is using NetEdit to manage AOS-CX switches. The engineer notices that a lot of third-party VoIP phones are showing up in the NetEdit topology. The engineer deletes these, but they are automatically rediscovered by NetEdit and added back in.
What should the administrator do to solve this problem?
To prevent the third-party VoIP phones from being rediscovered and added back into the NetEdit topology, the administrator should change the VoIP phone SNMP community string to something unknown by NetEdit. NetEdit uses SNMP for device discovery and management. By changing the SNMP community string, the phones will no longer respond to SNMP queries from NetEdit, thus preventing them from being rediscovered and added back into the topology.
I think it' A. Netedit uses LLDP to discover the devices, but it adds them in the topology only if the credentials set for the subnet work with those devices. Credential you can set are: - SNMP; - SSH; - SNMP. So, the best matching answer is A.
A is Correct
Page 79 Study Guide: Third- party support NetEdit supports any third- party devices that use SNMP. [Aruba Networks]
B is more correct here .. Netedit used LLDP by default as discovery.. so it will keep discovering every 5 minutes.
I'm afraid that this is correct, even if it's a stupid solution ...
initial discovery is using SNMP/REST API/SSH, for sure but once entering seed and found, it would use LLDP to discover all connected devices, so use B, as it is not practical to login each phone to change SNMP, as they are 'a lot'
A is Correct, agree with clupato2.
Sorry, i repeated SNMP twice. I meant to write Restful API (that work only with Aruba OS-CX devices).
I think its A. It say's Third-party devices. From the study guide, page 40: "NetEdit will now algo discover and display third-party devices that are using the stantard MIB's. Using SNMP with NetEDit, administrators can also enter SSH credentials for third-party devices.
I think it should be A, refer to the Video "https://www.youtube.com/watch?v=DMpF4RoSE2I". For Answer B, disable global LLDP will affect the other devices connected to the Switches. I understand it is not good idea.
B: If you prefer not to see the third-party VoIP phones in the NetEdit topology, you may have the option to disable CDP or LLDP on the switch ports to prevent the discovery and inclusion of those devices. However, disabling these protocols could limit the visibility and information available for network troubleshooting and monitoring.
Correction - answer is A: To manage VoIP phones in Aruba NetEdit, you would typically configure the SNMP settings on the VoIP phone itself, such as specifying the SNMP community string and enabling SNMP-based management. Aruba NetEdit can then communicate with the VoIP phone using SNMP to retrieve its configuration and perform configuration management tasks.
A is correct.
