Execution Commands
Using snmpget/snmpset commands are used to control and monitor the Gateway device.
Sample Snmpget Command
snmpget command is used for particular OID .
snmpget -OQ -Ir -v 2c -c public < WAN_IP(erouter0 IP Address> <OID>
For Example,
root@RaspberryPi-Gateway:~# snmpget -OQ -Ir -v 2c -c public 192.168.0.108 1.3.6.1.4.1.17270.50.2.2.2.1.1.3.10001
SNMPv2-SMI::enterprises.17270.50.2.2.2.1.1.3.10001 = "New_SSID" |
---|
Sample SnmpSet Command
snmpset command is used for particular OID .
snmpset -OQ -Ir -v 2c -c private <WAN_IP(erouter0 IP Address)> <OID> s <VALUE>
For Example,
It will update the existing SSID to new SSID and will broadcast the new one. You can confirm the same by running snmpget command again or by checking in /nvram/hostapd0.conf file
root@RaspberryPi-Gateway:~# snmpset -OQ -Ir -v 2c -c private 192.168.0.108 1.3.6.1.4.1.17270.50.2.2.2.1.1.3.10001 s RDKB_RPI_2G
SNMPv2-SMI::enterprises.17270.50.2.2.2.1.1.3.10001 = "RDKB_RPI_2G"

SnmpWalk Command
snmpwalk command is used for to fetch all the oids under a tree
Command :
snmpwalk -t 60 -c public -v 2c <WAN IP : erouter0 IP Address> 1.3.6.1.4.1.17270
Here, this will list all the oids under 17270
