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.

order to enable SNMP, click the Advanced
Settings
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.
With SNMP enabled, we can test it using the program snmpwalk in Linux. The listing below shows an example test script.
#!/bin/sh
IPADDR="10.223.187.2"
USRNAME="doodleAaron"
USRPASS="doodledoodle"
DATAPASS="d00dled00dle"
snmpwalk -m ALL -M ./ -v 3 -u $USRNAME -l authPriv -a SHA -A $USRPASS -x AES -X $DATAPASS $IPADDR 1.3.6.1.3.12314
Modify 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:
