# Monitoring QoS on E Series Routers

This chapter provides information for monitoring specific QoS configurations.

| Note: The E120 and E320 Broadband Services Routers output for monitor and show commands is identical to output from other E Series routers, except that the E120 and E320 router output also includes information about the adapter identifier in the interface specifier (slot/adapter/port).

QoS topics are discussed in the following sections:

- Monitoring Service Levels with Traffic Classes
- Monitoring Service Levels with Traffic-Class Groups
- Monitoring Queue Thresholds
- Monitoring Queue Profiles
- Monitoring Drop Profiles for RED and WRED
- Monitoring the QoS Scheduler Hierarchy
- Monitoring the Configuration of Scheduler Profiles
- Monitoring Shared Shapers
- Monitoring Shared Shaper Algorithm Variables
- Monitoring Forwarding and Drop Events on the Egress Queue
- Monitoring Forwarding and Drop Rates on the Egress Queue
- Monitoring Queue Statistics for the Fabric
- Monitoring the Configuration of Statistics Profiles
- Monitoring the QoS Profiles Attached to an Interface
- Monitoring the Configuration of QoS Port-Type Profiles
- Monitoring the Configuration of QoS Profiles
- Monitoring the QoS Configuration of ATM Interfaces
- Monitoring the QoS Configuration of IP Interfaces
- Monitoring the QoS Configuration of Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet Interfaces
- Monitoring the QoS Configuration of IEEE 802.3ad Link Aggregation Group Bundles
- Monitoring the Configuration of QoS Interface Sets
- Monitoring the Configuration of QoS Interface Supersets
- Monitoring the AAA Downstream Rate for QoS
- Monitoring QoS Parameter Instances
- Monitoring QoS Parameter Definitions
