Hi,

We bought a new S5720-EI, and imported the configuration from the old switch S2700, but the new switch was not able to be accessed through telnet, while the previous one was fine. We checked the IP connection, and telnet service, all is fine.

Do you have any further suggestions?

Thanks.

Hi,
The default configuration may vary with devices and versions.
Please check whether the telnet server is enabled.
[HUAWEI]telnet server enable
And check whether the following commands are configured on the user interface:
[HUAWEI] user-interface vty 0 4
[HUAWEI-ui-vty0] protocol inbound all/telnet
[HUAWEI-ui-vty0] authentication-mode aaa

Thanks,
I found the case introduce that the default the protocol allowed in V200R007 and later is SSH, while the in V200R006, the protocol is telnet, I think that is the reason.
Anyway, the telnet service is fine after the command added.
