Introduction
Dhcp Manager Support has been brought in completely for both ipv4 and ipv6 in Bannapi R4.This page is share information about integration of dhcp manager in BPI R4.
RdkDHCPManager is a component in RDK-B OS responsible for configuration and command control of DHCP client and server for both IPv4 and IPv6.
Code Changes :
We need to do the following code changes to integrate Dhcp Manager in the Bananapi R4 platform
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 " |
|---|
2.Register dhcp manager in CR
<component> |
|---|
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)}" |
|---|
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)}"us

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@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 SNMPv2-SMI::enterprises.17270.50.2.2.2.1.1.3.10001 = "Filogic_2g" root@Filogic-GW:~# |
