HPE 5900AF-48XG-4QSFP+ login issue

[Perczak]

Hello,

I am not able to login into the switch. Each time when I'm trying to do it(via ssh or console cable), I've got message: "remote side unexpectedly closed network connection". Sometiemes turning off device help, sometimes not.

The devices are two switches HPE 5900AF-48XG-4QSFP+ boundled in stack. The device works correctly.

The problem is get access to them. Since I met issue, I decide to upgrade firmware but it not helped me (currently: 5900_5920-CMW710-R2432P06.ipe).

Can anyone have any idea?

Regards

,Hi,

Can you set the authentication mode and default user role in the config?

Refer 'Logging in through SSH' on Pg.28.

Hello,

1. I ovserved that issue occured after configured and enabled ntp-service and clock.

2. After above configuration, I finished session and tried login again - issue occured.

3. I reseted switches without saving changes - i was able to login again.

Hi,

I don't think so NTP-service and clock not allow to login.

Now the issue resolved after reset the switch without saving changes.

Have you compared the before and after reboot config, what are the changes have you seen?

Thanks!

[Perczak]

The issue occuring after enabling ntp-service directly.

So, diference betwneen both configs concerns "ntp-service enable".
