Hello, I would like to read Qos statistics using a MIB Browser SNMP on a 3750. I woulf like to get the info that you get with command "sh mls qos interface gigabitEthernet 1/0/1 statistics" let say number of output packet with DSCP=48.

I think I have to query "cportQosDscpEgressPkts" on CISCO-PORT-QoS-MIB isn't ?

How is built the OID for a particular interface for a particula DSP value .... I'm on the right directrion ?

The OID for "cportQosDscpEgressPkts" seams to be .1.3.6.1.4.1.9.9.189.1.3.8.1.4 but with


snmpwalk -c "comstring" -v 2c "SwitchIP" .1.3.6.1.4.1.9.9.189.1.3.8.1.4

                                                             

I get this error messages


SNMPv2-SMI::enterprises.9.9.189.1.3.8.1.4 = No Such Object available on this agent at this OID



and on the Switch debug output:

Jun  1 06:34:47.112: SNMP: Packet received via UDP from XX.XX.XX.XX on VlanXXX
Jun  1 06:34:47.112: SNMP: Get request, reqid 1063020633, errstat 0, erridx 0 cportQosStatistics.8.1.2 = NULL TYPE/VALUE
Jun  1 06:34:47.112: SNMP: Response, reqid 1063020633, errstat 0, erridx 0 cportQosStatistics.8.1.2 = NO_SUCH_OBJECT_EXCEPTION
Jun  1 06:34:47.112: SNMP: Packet sent via UDP to XX.XX.XX.XX


the switch is a C3750 with IPSERVICESK9-M, Version 12.2(46)SE installed.


Any idea why I'm not able to get this OID ?
