Method used to change the maximum number of allowed login failures for the USG6000 series

0

—For a VTY or console administrator, the maximum number of allowed authentication failures can be set in the lock authentication-count command. The default value is 3.
# Set the threshold for authentication attempts to 5 on the console port.
system-view
[sysname] user-interface console 0
[sysname-ui-console0] lock authentication-count 5

—For users who log in through Telnet, SSH, web UI, FTP, SFTP, or SNMP, run the firewall blacklist authentication-count login-failed command to set the threshold for authentication attempts.
By default, the value is 3 for Telnet, SSH, web, FTP, and SFTP users or 6 for SNMP users.
# Set the threshold for authentication attempts to 5 for administrators who log in through the web UI.
system-view
[sysname] firewall blacklist authentication-count login-failed 5

If the number of consecutive wrong passwords exceeds the specified threshold, the client IP address is blacklisted to prevent more login attempts.
By default, the blacklist entry will be time out in 10 minutes. That is, the user can try to log in again using the same IP address 10 minutes later.

How can I change the lock time and maximum number of incorrect login attempts for the VP9000 series MCU?
1. Log in to the MCU as the administrator user in SSH2 mode. 2. Run the dis telnet-config command to check the values of user lock time and user login fail times. user lock time(minutes): indicates the lock time when the number of incorrect account or password attempts reaches the maximum. The default value is 5 minutes. The value ranges from 5 minutes to 60 minutes. user login fail times: indicates the maximum number of incorrect login attempts. The default value is 3. The value ranges from 3 to 5. 3. Run the sys telnet-config user-lock-time 5 command to change the lock time. In this example, the command sets the lock time to 5 minutes. 4. Run the sys telnet-config user-login-fail-times 5 command to change the maximum number of incorrect login attempts. In this example, the command sets the maximum number of incorrect login attempts to 5. 5. Run the save command to save the settings. 6. Run the reboot command to restart the MCU.

How can I change the maximum number of panes in automatic continuous presence?
To change the maximum number of panes in automatic continuous presence, configure data to not display continuous presence after joining a conference, or cancel automatic continuous presence: After a universal transcoding MCU participant joins a conference, automatic continuous presence is watched by default. The maximum number of panes can be configured as follows: Log in to the VP9600 series MCU command line interface (CLI), run the system-view conf-policy auto-mp-max-sub-pic-cnt 13 command to change the maximum number of panes in automatic continuous presence, and enter save to save the configuration. If the maximum number of panes is 1, a single pane is watched. To cancel the automatic continuous presence function, run the following command: system-view config-policy enable-auto-fill-manualmp 0 Enter save to save the configuration.
