Example for Configuring Monitoring Interfaces

Procedure

1. Set the SNMP version of the switch to SNMPv3.

   <HUAWEI> system-view
   [HUAWEI] sysname Switch
   [Switch] snmp-agent sys-info version v3

2. Configure user access rights.

   # Configure the MIB view.

   [Switch] snmp-agent mib-view included isoview iso

   # Configure the user group.

   [Switch] snmp-agent group v3 admin privacy write-view isoview acl 2001 

   # Configure the user.

   [Switch] snmp-agent usm-user v3 nms group admin

   # Configure data authentication and set the authentication password to admin@123.

   [Switch] snmp-agent usm-user v3 nms authentication-mode sha2-256
   Please configure the authentication password (8-64)                             
   Enter Password:                  //Enter the authentication password. It is admin@123 in this example.                                  
   Confirm Password:                //Confirm the password. It is admin@123 in this example.

   # Configure data encryption and set the authentication password to admin@123.

   [Switch] snmp-agent usm-user v3 nms privacy-mode aes256
   Please configure the privacy password (8-64)                                    
   Enter Password:                 //Enter the encryption password. It is admin@123 in this example.                                                 
   Confirm Password:               //Confirm the password. It is admin@123 in this example.

3. Configure a trap host and enable the switch to actively send traps to the NMS.

   [Switch] snmp-agent trap enable
   Warning: All switches of SNMP trap/notification will be open. Continue? [Y/N]:y
   [Switch] snmp-agent target-host trap address udp-domain 10.1.1.1 params securityname nms-admin v3 privacy

4. Configure the NMS.

   Set a user name and select a security level on the NMS running SNMPv3. Then set the authentication mode, authentication password, encryption mode, and encryption key according to the security level you select.

   

   The authentication parameters configured on the NMS must be the same as those on the switch. Otherwise, the NMS cannot manage the switch.

5. Configure input lines.

   # Enable the monitoring function for input lines 1 and 2.

   [Switch] monitor input 1 enable
   [Switch] monitor input 2 enable

   # Set the names of the input lines 1 and 2 to input1 and input2, and set the level of the input lines in normal state to low level.

   [Switch] monitor input 1 name input1 normal-state low-level
   [Switch] monitor input 2 name input2 normal-state low-level

6. Verify the configuration.

   After the configurations are complete, run the following command to check whether the SNMP configuration has taken effect.

   # View the configuration of the target host used to receive traps.

   [Switch] display snmp-agent target-host
   Target-host NO. 1                                                               
   -----------------------------------------------------------                     
     IP-address    : 10.1.1.1                                                      
     Domain        : -
     Source interface : -                                                          
     VPN instance  : -                                                             
     Security name : nms-admin                                                     
     Port          : 162                                                           
     Type          : trap                                                          
     Version       : v3                                                            
     Level         : Privacy                                                       
     NMS type      : NMS                                                           
     With ext-vb   : No                                                            
   -----------------------------------------------------------                     

   After the configurations are complete, check whether the monitoring device function has taken effect on monitoring interfaces.

   • When the cabinet door is opened (that is, the input line 1 changes from low level to high level), the switch sends a trap indicating that the input line 1 is abnormal to the NMS.

   • If the backup power supply is abnormal (that is, the input line 2 changes from low level to high level), the switch sends a trap indicating that the input line 2 is abnormal to the NMS.
