The Cisco 880 Series Integrated Services Router (ISR) offers a variety of features to manage network bandwidth. One of the main ways to manage bandwidth on the C887VA-K9 is through Quality of Service (QoS) mechanisms. QoS allows you to prioritize different types of network traffic, such as voice or video, to ensure that critical applications have the bandwidth they need to function properly.
One QoS mechanism is class-based shaping. This feature allows you to set a maximum rate of traffic that can be sent or received on a particular interface. For example, you can set a maximum rate of 1 Mbps for voice traffic and 2 Mbps for video traffic. This ensures that these critical applications will not be impacted by other types of traffic on the network.
Another QoS mechanism is policing. Policing allows you to control the amount of bandwidth used by specific types of traffic. For example, you can limit the amount of bandwidth used by peer-to-peer applications to prevent them from consuming too much bandwidth.
The router's traffic management features, such as access control lists (ACLs) and traffic shaping, can also be used to limit the amount of bandwidth available to specific network segments or applications.
Additionally, the Cisco IOS software's bandwidth command can be used to limit the bandwidth of an interface, and the Cisco Configuration Professional (CCP) can be used to set up bandwidth management policies.
Routing Protocols and ConfigurationRouting protocols are used to determine the best path for data to travel through a network. They are responsible for exchanging information between routers to update the routing table and make routing decisions. Different routing protocols have different characteristics and are suited for different types of networks.
The Cisco 887VA-K9 880 Series Integrated Services Router supports several routing protocols, including:
- Routing Information Protocol (RIP): a distance-vector protocol that uses hop count as a metric to determine the best path. It is simple to configure and is suitable for small to medium-sized networks.
- Open Shortest Path First (OSPF): a link state protocol that uses the shortest path to a destination as the metric. It is more complex to configure but is suitable for larger networks.
- Border Gateway Protocol (BGP): a path-vector protocol that is used to exchange routing information between routers in different autonomous systems (AS). It is typically used in large enterprise networks or in internet service provider (ISP) environments.
- Enhanced Interior Gateway Routing Protocol (EIGRP): a Cisco-proprietary protocol that is based on both distance-vector and link state routing. It is suited for large and complex enterprise networks.
To configure the routing protocol, you will need to access the router's command-line interface (CLI) and enter the appropriate commands. It is important to note that each protocol has its own set of commands and configuration options, so it is important to consult Cisco documentation and work with a Cisco-certified professional to properly configure the router for your specific use case.
High-Availability FeaturesThe Cisco 887VA-K9 880 Series Integrated Services Router supports several high-availability features to ensure that network operations can continue in the event of a failure or outage. These features include:
- Hot Standby Router Protocol (HSRP): This protocol allows for the configuration of a virtual router with a virtual IP address that can be shared between two or more routers. If the active router fails, the standby router takes over and continues to forward packets to the virtual IP address.
- Virtual Router Redundancy Protocol (VRRP): This protocol is similar to HSRP and allows for the configuration of a virtual router with a virtual IP address that can be shared between two or more routers. If the active router fails, the standby router takes over and continues to forward packets to the virtual IP address.
- Gateway Load Balancing Protocol (GLBP): This protocol allows for the load balancing of traffic between multiple routers, increasing network reliability and availability.
- Link Aggregation Control Protocol (LACP): This protocol allows for the bundling of multiple physical links into a single logical link, increasing network availability and bandwidth.
- FlexVPN: It is a simplified VPN solution that enables the deployment of secure, remote access VPNs.
- Dual ISP: It allows to use two different ISP connections to create a failover mechanism.

What is not covered by our warranty?
The reason why our warranty does not cover any problem caused by the following conditions:
(a) misuse of hardware; accidental damage; carelessness product(s) damage; shock; temperature beyond the specification of any product; faulty installation; operation; modification of goods;
(b) any misuse outside the instructions in the user manual for any specific product;
(c) damaged caused by other hardware or equipment. The warranty will void if the item is returned with physical damage, damage to the retail box, removed from the box, counterfeit labels/labelled by them, or any modifications of internal and external covers. Data loss or damages to any other equipment we do not cover by our offered warranty.
What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
