Management of Network Bandwidth
The CISCO2901/K9 Cisco 2901 Integrated Services Router (ISR) supports several features that can be used to manage network bandwidth. Some of the key features include:
- Quality of Service (QoS): QoS allows you to prioritize different types of traffic, such as voice or video, to ensure that they receive the necessary bandwidth and minimal latency.
- Traffic Shaping: Traffic shaping is a technique that can be used to control the rate at which traffic is sent or received on a network. This can be used to ensure that network resources are used efficiently and to prevent network congestion.
- Link Aggregation Control Protocol (LACP): LACP allows you to bundle multiple physical interfaces together to form a single logical interface. This can be used to provide redundancy and increased bandwidth.
- Class-Based Weighted Fair Queuing (CBWFQ): CBWFQ allows you to configure different queues for different types of traffic, and assign different levels of bandwidth to each queue.
- Weighted Random Early Detection (WRED): WRED allows you to configure different drop probabilities for different types of traffic, which can be used to prevent network congestion.
These features can be configured and enabled/disabled through the Cisco IOS CLI or web interface, depending on the needs of the organization and network. It’s also important to consult the documentation and support of the router for the specific features and their configuration options.
