Designed for video and other high bandwidth applications. Supports a variety of interface types, those commonly used by Service Providers.
What are QoS groups?
QoS Groups are locally significant groups that can categorize different classes of traffic together under one group, you can configure 1024 qos groups (0-1023). Since it is only locally significant to the router, it can only be set in the Ingress direction and matched in the Egress direction.
How do you set QoS classification?
Configuration for QoS:
- Step 1 Open web browser and enter 192.168.
- Step 2 Enter the username and password of your modem.
- Step 3 Go to Quality of Service, please check Enable QoS.
- Step 4 Go to Queue Config, then click add button to add a queue.

What Cisco devices use Iosxr?
IOS XR is a train of Cisco Systems’ widely deployed Internetworking Operating System (IOS), used on their high-end Network Convergence System (NCS), carrier-grade routers such as the CRS series, 12000 series, and ASR9000 series.
What is QoS group value?
between 0 and 99
The QoS group value is a number between 0 and 99 that is set using the set qos-group command. The group value can be used to classify packets into QoS groups based on a prefix, autonomous system, and community string. A packet is marked with a QoS group value only while it is being processed within the device.
Where should QoS marking be performed?
Where should QoS marking be performed? Answer A. switches and routers in the network should be configured to properly prioritize markings of traffic in queues.
How do you classify QoS?
System supports three types of QoS: application QoS, IP QoS and role QoS. IP QoS: Controls the bandwidth of designated IP addresses. Role QoS: Also called role-based QoS. It controls the bandwidth of designated roles.
What is the difference between ASR and ISR?
The biggest difference between Cisco ASR and ISR routers is that ASR routers are for enterprises and service providers, whereas ISR are for customers with small- or medium-sized networks. In terms of similarities, both Cisco ASR and ISR routers offer secure WAN connectivity.
