As mentioned in the article, this sort of configuration works well for public access and allows unknown users access to only the internet. Recently I had a request to limit the bandwidth that users had access to on the guest network. I had never configured something like this before but after thinking about it for awhile it made sense. You don’t want someone to get onto your guest network and be able to have access to the entire bandwidth available to the ASA.
CLI Book 2: Cisco ASA Series Firewall CLI Configuration Guide, 9.5 - Quality of Service [Cisco Adaptive Security Virtual Appliance (ASAv)] Have you ever participated in a long-distance phone call that involved a satellite connection?
The conversation might be interrupted with brief, but perceptible, gaps at odd intervals. Those gaps are the time, called the latency, between the arrival of packets being transmitted over the network. Some network traffic, such as voice and video, cannot tolerate long latency times. Cisco ASA QOS. Cisco ASA QOS It may be desirable to rate-limit traffic to various hosts or subnets on your network.
The Cisco ASA has some very limited QOS capabilities built in (better QOS features are available on Cisco IOS routers). To apply a basic rate limit, use the “policing” feature. It is configured by matching a class of traffic with a “class-map“, setting rules with a “policy-map” to “police” your traffic class at a given rate, and then applying the policy to an interface with the “service-policy” command. *NOTE* only one service-policy may be active on an interface at a time. Video qos. Comparing Traffic Policing and Traffic Shaping for Bandwidth Limiting. Introduction This document clarifies the functional differences between shaping and policing, both of which limit the output rate.
Though both mechanisms use a token bucket as a traffic meter to measure the packet rate, they have important functional differences. Enterprise QoS Solution Reference Network Design Guide - Quality of Service Design Overview [Design Zone for IPv6] What is the Cisco QoS Toolset?
This section describes the main categories of the Cisco QoS toolset and includes the following topics: Classification and Marking toolsPolicing and Markdown toolsScheduling toolsLink-specific toolsAutoQoS toolsCall Admission Control tools Cisco provides a complete toolset of QoS features and solutions for addressing the diverse needs of voice, video and multiple classes of data applications. QoS on the Cisco ASA Configuration Examples. Introduction This document explains how Quality of Service (QoS) works on the Cisco Adaptive Security Appliance (ASA) and also provides several examples on how to implement it for different scenarios.
You can configure QoS on the security appliance in order to provide rate limiting on selected network traffic, for both individual flows and VPN tunnel flows, in order to ensure that all traffic gets its fair share of limited bandwidth. The feature was integrated with Cisco bug ID CSCsk06260. Prerequisites.
