We need to do the following code changes to integrate Dhcp Manager in the Bananapi R4 platform

1 2.1.Enable both the dhcp manager and configurable wan interface distro features in our configuration file for this feature to work seamlessly,

...

DISTRO_FEATURES_append = " dhcp_manager " DISTRO_FEATURES_append = " rdkb_configurable_wan_interface"

2.2 2.Register dhcp manager in CR

<component> <name>eRT.com.cisco.spvtg.ccsp.dhcpmgr</name> <version>1</version> </component> </components>

3 2.3 Enable the Cflags for both the distros in the ccsp_common.inc file

...

  CFLAGS_append  += " ${@bb.utils.contains('DISTRO_FEATURES', 'dhcp_manager', '-DFEATURE_RDKB_DHCP_MANAGER', '', d)}"
  CFLAGS_append  += " ${@bb.utils.contains('DISTRO_FEATURES', 'rdkb_configurable_wan_interface', '-DFEATURE_RDKB_CONFIGURABLE_WAN_INTERFACE', '', d)}"

2.4 . Updating the psm data base

  CFLAGS_append  += " ${@bb.utils.contains('DISTRO_FEATURES', 'dhcp_manager', '-DFEATURE_RDKB_DHCP_MANAGER', '', d)}"
  CFLAGS_append  += " ${@bb.utils.contains('DISTRO_FEATURES', 'rdkb_configurable_wan_interface', '-DFEATURE_RDKB_CONFIGURABLE_WAN_INTERFACE', '', d)}"

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@Filogic-GW:~# snmpget -OQ -Ir -v 2c -c public 192.168.2.159 1.3.6.1.4.1.17270.50.2.2.2.1.1.3.10001
