MIBs Used for QoS
CISCO-CLASS-BASED-QOS-MIB
Configuring QoS
You configure QoS through the command line interface (CLI). For instructions, see the Cisco 7304
Internet Series Router Software Configuration Guide, “Configuring Quality of Service.”
Accessing QoS Configuration Information and Statistics
The CISCO-CLASS-BASED-QOS-MIB provides access to QoS configuration information and
statistics. Although you cannot use SNMP to configure QoS on the router, you can use SNMP to access
QoS configuration information that has been configured through the CLI.
QoS Indexes
The indexes for accessing QoS configuration information and QoS statistics are:
• cbQosPolicyIndex—System-assigned index that identifies a policy map attached to an interface.
(When attached to an interface, a policy map is known as a service policy.)
• cbQosObjectsIndex—System-assigned index that identifies each unique run-time instance of a QoS
feature (for example, policy map, class map, match statement, and feature action).
• cbQosConfigIndex—System-assigned index that identifies each unique configuration of a QoS
feature (for example, a class map or police action). Note that QoS objects with the same
configuration share the same cbQosConfigIndex.
• cbQosREDValue—The IP precedence or IP differentiated services code point (DSCP) of a Weighted
Random Early Detection (WRED) action. It is used as the index for configuration information and
statistics for each RED class.
Figure A-2 shows how these indexes provide access to QoS configuration information and statistics.
