Huawei Memory Graphs Not polling

[Salman75]

I am trying to poll Memory of my huawei switch in cacti but its not working. i am using SNMP - Generic OID Template. i used same for polling CPU utilization and it worked but in case of memory it didn't. when i do snmp walk it returns correct value.

snmpwalk -v 2c -c public IP 1.3.6.1.4.1.2011.6.3.5.1.1.4
iso.3.6.1.4.1.2011.6.3.5.1.1.4.0.0.0 = Gauge32: 162135372


Kindly suggest any correction that i should made to get required output.
