NMS300 config backup with telnet disabled?
Hello everybody, we would like to use NMS300 to save the config of our 40 Netgear Switches automatically every night, but it seems that this requires telnet to be enabled on all switches. Is this...
Hi cp42,
Your testing result is right, telnet is required when do M4100 backup/restore (M4100 is a special case). However your idea (using encrypted protocol to do backup) is a very good. What you can do is to post suggestions and ideas at the Idea Exchange board. Adding kudos to the ideas will help as development team will be reviewing the post that has the most kudos for considering it to add to the product's future release.
Thank you again.
Hi cp42
Welcome to Netgear Community!
NMS300 support device credential via SNMPv1, SNMPv2c, SNMPv3, Telnet, SSH, HTTP and HTTPS, for Netgear Switches, we recommend to use SNMP and HTTP, then telnet has no need to enable because of security concern. That means, if you alreay select Telnet for device credential, it has to be enable when run a schedule backup task.
On NMS300, you can add one time or schedule task to backup devices configuration, get User Manual (page120) for more detail.
The new NMS300 build v1.5.0.18, which support to manage M4300 series switch:

Bruce, thanks for your feedback, but it doesn't solve the problem for me.
I know that NMS300 offers the configuration of device credentials for several protocols including ssh and that I can associate an ssh credential with my switches, but when I run a config backup profile for these switches I get the error message "No valid Telnet credential". I guess this means that I have to configure a Telnet credential for these switches because the config backup does work only via Telnet, right?
If it's possible to configure a config backup profile to use an encrypted connection (http and snmp are also unencrypted an therefore offer no advantage regarding security when compared to telnet) please let me know how this is possible...
Thank you!
