How to Configure QOS for VOIP Traffic on Cisco Router

Configure QoS for VOIP Voice Traffic: By using quality of service (QoS) on Cisco network devices helps provide both bandwidth and priority to certain types of network traffic. The network administrator tells the network devices which traffic requires what bandwidth and priority. It’s important to understand the difference between bandwidth and priority. Priority means network device like Cisco Router or Switch give that traffic priority by sending it before than other traffic and they give the traffic bandwidth by sending more of it than other traffic. QoS configuration is very complex. There are many different ways of implement QoS on Cisco Routers. Follow the step by step QoS configuration on a Cisco router. Step 1: Define the VOIP traffic in ACL You have to define the traffic on Router which traffic you want to give QoS (Priority or dedicated Bandwidth), which you can accomplish either using an access control list […]
