Scheduling jobs 
You can schedule a job to automatically run a command or a set of commands without administrative 
interference. The commands in a job are polled every minute. When the scheduled time for a command 
is reached, the job automatically executes the command. If a confirmation is required while the 
command is running, the system automatically inputs Y or Ye s . If characters are required, the system 
automatically inputs a default character string, or in puts an empty character string...

{ Input a view name in its complete form. Most commonly used view names include  monitor for 
user view,  system for system view, GigabitEthernet x/x/x, and Ten-GigabitEthernet x/x/x for 
Ethernet interface view, and  Vlan-interfacex for VLAN interface view.  
{ The time ID ( time-id) must be unique in a job. If two time and command bindings have the same 
time ID, the one configured last takes effect.  
Scheduling a job in the non-modular approach 
Perform one of the following commands in user...

Disabling Boot ROM access 
By default, anyone can press Ctrl+B during startup to enter the Boot menu and configure the Boot ROM. 
To protect the system, you can disable Boot ROM ac cess so the users can access only the CLI.  
You can also set a Boot ROM password the first time you access the Boot menu to protect the Boot ROM. 
To view Boot ROM accessibility status, use the  display startup command. For more information about the 
display startup  command, see Fundamentals Command Reference ....

Step Command Remarks 
1.  Enter system view. 
system-view  N/A 
2.  Configure temperature 
thresholds for an IRF 
member device.  temperature-limit 
slot 
slot-number  hotspot  
sensor-number  lowerlimit 
warninglimit    Optional. 
By default, the lower threshold is –5°C 
(23°F), and the warning threshold is 55°C 
(131°F). 
The warning threshold must be higher than 
the lower threshold.

Diagnosing transceiver modules 
The device provides the alarm function and digital diagnosis function for transceiver modules. When a 
transceiver module fails or inappropriately operates, you can check for alarms present on the transceiver 
module to identify the fault source or examine the...

Automatic configuration introduction 
Automatic configuration enables a device without any configuration file to automatically obtain and 
execute a configuration file during startup. Automatic configuration simplifies network configuration, 
facilitates centralized management, and reduces maintenance workload.  
To implement automatic configuration, the network administrator saves configuration files on a server 
and a device automatically obtains and executes a specific configuration file....

 146 
How automatic configuration works 
Automatic configuration works in the following manner: 
1. During startup, the device sets the first up interface (if up Layer 2 Ethernet ports exist, the VLAN 
interface of the default VLAN of the Ethernet ports is selected as the first up interface. Otherwise, 
the up Layer 3 Ethernet interface with the smallest  interface number is selected as the first up 
interface) as the DHCP client to request parameters from the DHCP server, such as an IP address 
and name...

 147 
Using DHCP to obtain an IP address and other configuration 
information 
Address acquisition process 
As previously mentioned, a device sets the first up interface as the DHCP client during startup. The DHCP 
client broadcasts a DHCP request, where the Option 55 field specifies the information that the client 
wants to obtain from the DHCP server such as the configuration file name, domain name and IP address 
of the TFTP server, and DNS server IP address. 
After receiving the DHCP response from...

 148 
To configure static address pools, you must obtain corresponding client IDs. To obtain a device’s client ID, 
use the display dhcp server ip-in-use command to display address binding information on the DHCP 
server after the device obtains its IP address through DHCP. 
Obtaining the configuration file from the TFTP server 
A device can obtain the following files from the TFTP server during automatic configuration: 
•   The configuration file specified by the Option 67 or file field in the DHCP...
