Run from snmp manager

Make sure that net-snmp is configured with the correct community (snmp v1 and v2) or username / password(s) (authentication and encryption password). This community or user should have write privileges. Therefore it's advisable to use snmp v3 and to restrict access on agent to the manager. snmpconf can help create a snmp config file.

[admin@hgw] /snmp community> print value-list
                       name: public          private
                  addresses: 192.168.20.2/32 192.168.20.2/32
                   security: none            authorized
                read-access: yes             yes
               write-access: no              yes
    authentication-protocol: MD5             MD5
        encryption-protocol: DES             DES
    authentication-password:                 ******
        encryption-password:                 ******

Change hostname of router (agent) in script:

use constant AGENT => 'gateway';

Change 'gateway' info the hostname or ip address of your router.
