Appendix C – Using SNMP
Before you can use SNMP, you need to open
up the firewall at port 161 for UDP traffic. In the GUI, navigate to Network Configuration → Firewall. Under the section Open
ports on router, add a new rule like that shown
in the figure below. Click Add, and after the page reloads, click Save & Apply.
Fig. 1 – Opening the Firewall for SNMP
order to enable SNMP, click the Advanced
button in the bottom left corner of the GUI. Then navigate to services → SNMPD. Uncheck Disable SNMPD Service, and fill in the table. Finally click Save & Apply.
SNMP enabled, we can test it using the program snmpwalk in Linux. The listing below
shows an example test script.
snmpwalk -m ALL -M ./ -v 3 -u $USRNAME -l authPriv -a SHA
-A $USRPASS -x AES -X $DATAPASS $IPADDR 188.8.131.52.3.12314
the user login information in snmpwalk.sh using the information you
used in the web GUI setup. The MIB is defined in /usr/lib/lua/smithsnmpd/mibs/wifi.lua and needs to be modified to
be able to support the information defined in WIFI-MIB.txt which is available here:
