nrcmd>dhcp attachExtension post-send-packet smleg 11
nrcmd>extension smlegext create dex cnrleg.dll cnrLegPostPacketDecode
nrcmd>dhcp attachExtension post-packet-decode smlegext 12
nrcmd>save
nrcmd>server DHCP reload
Note You must use the cfg-dir full path in the init-args argument.
Note You must use a slash ("/") and not a back-slash ("\") as the path separator.

•Configure the following:
nrcmd>extension smleg create dex libcnrleg.so cnrLegPostSendPacket
nrcmd>extension smleg set init-entry=cnrLegInitEntry
nrcmd>extension smleg set init-args=cfg-dir/cnrleg.cfg
nrcmd>dhcp attachExtension post-send-packet smleg 13
nrcmd>extension smlegext create dex libcnrleg.so cnrLegPostPacketDecode
nrcmd>dhcp attachExtension post-packet-decode smlegext 14
nrcmd>save
nrcmd>server DHCP reload
Note You must use the cfg-dir full path in the init-args argument.
