No. Data
1 Maximum VTY user interfaces
2 (Optional) ACL code to restrict incoming and outgoing calls on VTY user interfaces
3 Idle timeout period, number of characters in each line displayed on a terminal screen

4.3.2 Configuring the Maximum Number of VTY User Interfaces
This section describes how to limit the number of users logging in to the router by configuring
the maximum number of VTY user interfaces.
Context
The maximum number of VTY user interfaces equals the total number of users allowed to log
in to the router using Telnet or SSH.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
user-interface maximum-vty number
The maximum number of VTY user interfaces is set. By default, the maximum number of VTY
user interfaces is 5.
NOTE
When the maximum number of VTY user interfaces is set to zero, no user (including the network
administrator) can use a VTY user interface to log in to the router.
If the set maximum number of VTY user interfaces is smaller than the maximum number of
online users, current online users will not be affected and no additional configuration is required.
If the set maximum number of VTY user interfaces is greater than the maximum number of
current interfaces, the authentication mode must be set for newly added user interfaces.
