SNMP Polling and Traps Configuration on Huawei Router

Pre-config: (assuming Loopback0 is your source interface to send those SNMP traffic)

interface LoopBack0
    description _ Loopback for Huawei Router
ip address 192.168.10.100 255.255.255.255

1. Configure SNMP (version can be set to all to support v1,v2c and v3)

2. Configure SNMP engine ID and community string (with ACL)

snmp-agent
snmp-agent local-engineid 800007DB0000ABC11D2D56
snmp-agent community read cipher %^%#*JAZgT9C0XPI~”fyw36753Mkn&ZZ]3Nh+u(n%|X%^# acl 1234acl number 1234
 description SNMP Server
  rule 10 permit source 192.168.20.199 0
  rule 20 deny

Note: SNMP EngineID is use to uniquely identify an SNMP entity. If you want to setup manually, preferably to follow the standard conventions (Huawei engine ID + (IP or Mac Addrss of the router). FYI, Huawei device engine ID is 800007DB based on IANA private engine ID’s first 4 bytes in hexadecimal format.

Sample Output: (SNMP community configured as clear text will be translated to encrypted characters)

snmp-agent usm-user v3 <username> privacy-mode 3des168/aes128/aes192/aes256/des56

If you try to use old authentication type:
snmp-agent usm-user v3 FNT authentication-mode sha
Please configure the authentication password (8-255)
Enter Password: <type here ABcD123456>
Confirm Password: <type here ABcD123456>
Warning: The algorithm SHA1 is insecure. Using SHA2-256 or higher algorithm is recommended.
