How to suspend telnet session on Huawei switch or router

Hi ytlo,
You can use the cut access-user command to force users offline.
For details, please refer to

What the control-shift-6 x do is that, when a user telnet, say from a switch to a router, he can issue control-shift-6 x in the router session to go back to the switch session. If he wants to resume the router session, he just press enter on the empty command prompt. This means he can switch back and forth between the switch and the router, without the need to establish the telnet session every single time.

As I know, Huawei devices do not have such shortcut keys. You can create two sessions at the same time on your terminal.
