68 Single-line input In single-line input mode, all banner information is input in the same line. The start and end characters of the input text must be the same and are not part of the banner information. The input text, together with the command keywords, cannot exceed 510 characters. In this mode, do not press Enter after typing the banner information. For example, to configure a banner like “Have a nice day.”, use the following command: system-view [System] header shell %Have a nice day.% Multiple-line input In multiple-line input mode, you can press Enter to separate the banner information in multiple lines. In this case, up to 2000 characters can be typed. Multi-line input can be performed with the following methods: • Method I—Press the Enter key directly after the command keywords, type the banner information, and finish your setting with the % character. The % character is not part of the banner information. For example, to configure a banner like “Have a nice day. Please input the Password!”, use the following commands: system-view [System] header shell Please input banner content, and quit with the character '%'...System prompt Have a nice day. Please input the Password!% • Method II—Type a character after the command keywords at the first line, and then press Enter. Type the banner information, and finish your setting with the character you typed at the first line. The start character and the end character are not part of the banner information. For example, to configure a banner like “Have a nice day. Please input the Password!”, use the following commands: system-view [System] header shell A Please input banner content, and quit with the character 'A'...System prompt Have a nice day. Please input the Password!A • Method III—Type multiple characters after the command keywords at the first line (with the first and last characters being different), and then press Enter. Type the rest banner information, and finish your setting with the first character you typed at the first line. The first input character at the first line and the end character are not part of the banner information. For example, to configure a banner like “Have a nice day. Please input the Password!”, use the following commands: system-view [System] header shell AHave a nice day. Please input banner content, and quit with the character 'A'...System prompt Please input the Password!A Configuring the maximum number of concurrent users Follow these steps to configure the maximum number of users that can enter the system view simultaneously: 69 To do… Use the command… Remarks Enter system view system-view — Configure the maximum number of concurrent users configure-user count number Optional By default, up to two users are allowed to perform operations in system view at the same time.

Configuring the exception handling method You can configure the system to handle software exceptions with either of the following methods: • reboot—The system reboots to remove exceptions. • maintain—The system stays in the current state. You need to manually recover the system, such as rebooting the system. Sometimes, it is difficult to make a system problem to reoccur, or some prompts that are printed during the failure are lost after a reboot. In this case, you can use this method to keep the abnormal state and troubleshoot the problem. Follow these steps to configure the exception handling method: To do… Use the command… Remarks Enter system view system-view — Configure the exception handling method system-failure { maintain | reboot } Optional By default, the system adopts the reboot method to handle exceptions.
