As an IT administrator, understanding the basics of bandwidth limiting with a Cisco 3400 ME is an important part of maintaining a secure and efficient network. In this article, we’ll look at the basics of how to limit the bandwidth on a Cisco 3400 ME, as well as some tips and tricks for troubleshooting common issues.
The Cisco 3400 ME is a high-performance integrated services router that provides a wide range of services, including voice, video, data, and security. This router also has a feature called bandwidth limiting, which allows you to limit the amount of data that can pass through the router at any given time. This can be used to control the amount of traffic that passes through the network, as well as to enforce specific usage policies.
To begin, you need to configure the interface on the Cisco 3400 ME. In order to limit the bandwidth on a particular interface, you need to configure the interface with the “bandwidth” command. This command will allow you to specify the maximum amount of bandwidth that can be used. For example, if you wanted to limit the bandwidth on an interface to 10 Mbps, you would use the following command:
“interface GigabitEthernet0/1
bandwidth 10”
Once you have configured the interface with the bandwidth command, you can then begin to apply bandwidth limiting to specific traffic. This can be done by using the “traffic-policy” command. This command allows you to specify the policies for a particular type of traffic. For example, if you wanted to limit the bandwidth for web traffic to 10 Mbps, you would use the following command:
“traffic-policy web-traffic
match protocol http
bandwidth 10”
Once the traffic policy has been configured, you can then apply it to the interface by using the “apply-policy” command. This command allows you to specify the traffic policy that should be applied to the interface. For example, if you wanted to apply the web-traffic policy to the GigabitEthernet0/1 interface, you would use the following command:
“apply-policy web-traffic
interface GigabitEthernet0/1”
Once the traffic policy has been applied to the interface, you can then begin to monitor the traffic and verify that the bandwidth limiting is working correctly. This can be done by using the “show policy” command. This command will display the traffic policy that is currently applied to the interface, as well as the amount of traffic that is being limited.
In addition to monitoring the traffic, you can also use the “show interface” command to view the current bandwidth usage of the interface. This command will display the current rate of traffic that is passing through the interface, as well as the bandwidth limit that has been configured.
Finally, if you encounter any issues with the bandwidth limiting, you can use the “debug policy” command. This command will display detailed information about the traffic policy, as well as any errors that may be occurring. This can be useful for troubleshooting any issues with the bandwidth limiting.
Overall, understanding the basics of bandwidth limiting with a Cisco 3400 ME is an important part of maintaining a secure and efficient network. By following the steps outlined in this article, you should be able to successfully limit the bandwidth on your network.
