Network Engineering Asked by DevOps on December 12, 2021
We need to manage switches HPE OfficeConnect 1920S remotely but only HTTP/HTTPS Administration is available.
HPE 1920S has an special operating system, neither Procurve nor Comware. We are looking for technical documentation which describes how to enable SSH/TFTP services but we have not found anything yet.
Do you know how we could enable SSH/TFTP services in HPE 1920S switches?
Please note that suggested solution (inserting "ip telnet server enable" into startup-config file and then enabling ssh) works only till firmware version PD.02.06.stk (including).
When upgrading to newer firmware it seems that telnet and ssh servers have been removed and the suggested solution does not work anymore.

Well, actually you CAN enable telnet and ssh. It's completely unsupported, but anyway:
!Current Configuration: ! !System Description "HPE OfficeConnect Switch 1920S 24G 2SFP PoE+ (370W) JL385A, PD.02.06, Linux 3.6.5-a07f8920, U-Boot 2012.10-00118-g3773021 (Oct 11 2016 - 15:39:54)" !System Software Version "PD.02.06" !System Up Time "0 days 0 hrs 6 mins 3 secs" !Additional Packages HPE QOS,HPE IPv6 Management,HPE Routing !Current SNTP Synchronized Time: SNTP Last Attempt Status Is Not Successful ! network protocol none network parms 10.1.1.50 255.255.255.0 10.1.1.1 vlan database exit ip telnet server enable configure sntp client mode unicast sntp server "10.1.1.1"

Here is original thread: https://community.hpe.com/t5/Web-and-Unmanaged/How-to-Enable-Telnet-and-SSH-on-HPE-1920s-OfficeConnect/td-p/6988775 , today I enabled telnet on my 1920S using this trick.

See the following link: https://glazenbakje.wordpress.com/2012/08/21/hp-v1910-secret-commando-list-how-to-enable-it/
Both the V1910 and the (old) 1920 have a technician's CLI, which is completely unsupported, but works good enough. Keep in mind that this is not about the 1920S. I just ordered a demo model of the 1920S and will get it on monday. Will test if the CLI is accessible then.

18xx and 19xx are "smart-managed" or web-managed only, no telnet, no SSH. Some 1920s have a minimal serial/USB console though. The switch has TFTP and SFTP clients but no server.
I've looked into 1810 switches a while ago (how to automate config backups using curl
). These SOHO switches apparently use firmware made by the chipset manufacturer that has been branded by HP. 1810v1 and 1810v2 differ significantly by site structure and backup file format, so that they're actually two different devices.
Depending on what you're trying to do, you might be able to accomplish some automated management using curl
, but if you want a real console interface you'll need to replace the switch.
