Huawei AR2200 Series - Optional)Setting Limit on Incoming and Outgoing Calls of VTY User Interfaces

Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
user-interface maximum-vty number
The maximum VTY user interfaces that can log in to the router is set. By default, the maximum
number of VTY users is 5.
NOTE
When the maximum number of VTY user interfaces is set to zero, any user (including the NMS user) cannot
log in to the router by using a VTY user interface.
If the maximum number of VTY user interfaces to be configured is smaller than the maximum
number of current interfaces, current online users will not be affected and no addition
configuration is needed.
If the maximum number of VTY user interfaces to be configured is larger than the maximum
number of current interfaces, the authentication mode and password need to be configured for
newly added user interfaces.
For newly added user interfaces, the system defaults to password authentication.
For example, a maximum of five users are allowed online. To allow 15 VTY users online at the
same time, you need to run the authentication-mode command and the set authentication
password command to configure authentication modes and passwords for user interfaces from
VTY 5 to VTY 14. The command is run as follows:
<Huawei> system-view
[Huawei] user-interface maximum-vty 15
[Huawei] user-interface vty 5 14
[Huawei-ui-vty5-14] authentication-mode password
[Huawei-ui-vty5-14] set authentication password cipher huawei

command in the system view to create an ACL and enter the ACL view. Then, run the rule
command to add rules to the ACL.
