Installation

The 'snmp-2.4.x.npk' (less than 150KB) package for installation of SNMP is required. The package can be downloaded from MikroTik’s web page www.mikrotik.com. To install the package, please upload it to the router with ftp and reboot. You may check to see if the SNMP package is installed with the command:

[MikroTik] > system package print

Hardware Resource Usage

When the SNMP is enabled, it uses approximately 2MB of RAM. When using SNMP, memory usage estimates should be made, system resources should be monitored, and RAM should be increased accordingly.

SNMP Setup

SNMP management can be accessed under the /snmp menu. Use the set command to configure it and enable the service:

[MikroTik] snmp> set contact=Sysadmin-555-1212 location=MikroTik enabled=yes
[MikroTik] snmp> print
     contact: Sysadmin-555-1212
    location: MikroTik
     enabled: yes
[MikroTik] snmp>

Description of arguments:

contact-info, location - Informative only settings for the NMS.
enabled - (yes / no). SNMP service is disabled by default.

Tools for SNMP Data Collection and Analysis

MRTG (Multi Router Traffic Grapher) is the most commonly used SNMP monitor.
