Configuring Telnet and SSH on the USG6000

Configure Telnet and SSH on the USG6000 as follows:

1. Set the administrator IP addresses that can access the device remotely. The administrator cannot use IP addresses that are not specified in the ACL to remotely access the device through Telnet or SSH.

2. Configure connection number limit on the VTY administrator interface. Limit the number of concurrent remote login sessions on the device to avoid occupying two many system resources, facilitate centralized operation and maintenance, and ensure normal operation when a fault occurs.

3. Configure login through Telnet or SSH.
