Manual:SNMP Write

Overview

v3 MikroTik RouterOS supports SNMP write for some functions. SNMP write allows to change router configuration with SNMP requests. Consider to secure access to router or to router's SNMP, when SNMP and write-access are enabled.

Writable options

To change settings by SNMP requests, use the command below to allow SNMP write for the selected community, Write-access option for SNMP is available from v3.14,

/snmp community set <number> write-access=yes

System Identity

It's possible to change router system identity by SNMP set command,

snmpset -c public -v 1 192.168.0.0 1.3.6.1.2.1.1.5.0  s New_Identity

• snmpset, SNMP application used for SNMP SET requests to set information on a network entity;
• public, router's community name;
• 192.168.0.0, IP address of the router;
• 1.3.6.1.2.1.1.5.0, SNMP value for router's identity;

SNMPset command above is equal to the RouterOS command,

/system identity set identity=New_Identity

Reboot

It's possible to reboot the router with SNMP set commamd, you need to set value for reboot SNMP settings, which is not equal to 0,

snmpset -c public -v 1 192.168.0.0 1.3.6.1.4.1.14988.1.1.7.1.0 s 1

• 1.3.6.1.4.1.14988.1.1.7.1.0, SNMP value for the router reboot;
• s 1, snmpset command to set value, value should not be equal to 0;

Reboot snmpset command is equal to the RouterOS command,

/system reboot

Run Script

SNMP write allows to run scripts on the router from system script menu, when you need to set value for SNMP setting of the script,

 
snmpset -c public -v 1 192.168.0.0 1.3.6.1.4.1.14988.1.1.8.1.1.3.X s 1

• X, script number, numeration starts from 1;
• s 1, snmpset command to set value, value should not be equal to 0;

The same command on RouterOS,

/system script> print
