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,
Thanks for your follow-up feedback.
I guess you associate telnet credential to device, however disable it on switch device side, that might be the reason to see the error message "No valid Telnet credential" (please login NMS300, go to Resources->Devices, click device to see "Device Detail View", select "credential" at the bottom, to view which credential are associated). Back to your question, Telnet is not required to backup/restore configuration file most time.
Which protocols to implement backup and restore? it depends on the type of devices, most Managed Switch use SNMP, most smart switch use HTTP or HTTPS, some Prosafe Firewall use HTTPS.
In out testing lab, we tried M6100 (Managed Switch, only associate SNMPv3) and S3300-52X (Smart Switch, associate SNMPv2 and HTTPS), schedule backup/restore on both devices working well.
If you have concern the unencrypted connection when do backup/restore, you can select SNMPv3 or HTTPS (please note that not all devices support backup/restore via HTTPS).
The latest NMS300 build fixed a schedule backup bug, please upgrade and try with my suggestion. If still can't resolve your issue, let me know the model of your Netgear switch.
