Hi Sir/Miss

i am using net-snmp on CentOS. when i try to using snmpwalk to get OID "1.3.6.1.4.1.9.9.166.1.5.1.1.2" from cisco 2821. it display No Such Object available on this agent at this OID.

i have cisco MIB "CISCO-CLASS-BASED-QOS-MIB" . it load at net-snmp. i run snmptranslate, it can successful. please look at below:

[root@compag-logsvr mibs]# snmptranslate -m +CISCO-CLASS-BASED-QOS-MIB -IR -On cbQosConfigIndex

.1.3.6.1.4.1.9.9.166.1.5.1.1.2

[root@compag-logsvr mibs]# snmptranslate -m +CISCO-CLASS-BASED-QOS-MIB -IR -On cbQosCMPostPolicyByte
.1.3.6.1.4.1.9.9.166.1.15.1.1.9

when i try to run snmpwalk , it retrun "No Such Object available on this agent at this OID" i check the mib locator in cisco website. it can support "CISCO-CLASS-BASED-QOS-MIB" . why i can't get OID?

[root@compag-logsvr mibs]# snmpwalk -v 2c hostip -c snmpkey -m +all 1.3.6.1.4.1.9.9.166.1.15.1.1.9
CISCO-CLASS-BASED-QOS-MIB::cbQosCMPostPolicyByte = No Such Instance currently exists at this OID
