In this article I will describe the Cisco digital network architecture DNA. Cisco digital network architecture provide the centralized management for all the networking devices. We manage the networking devices by taking their console by SSH or putty. If there are a lots of devices in the network then we need to manage each device separately.
A Switch is a device which works at Data link layer in networking. A Switch receive and transmit the data packets between different end devices. Switch inspect the header section of the received packet to check the destination IP address and MAC address then forward accordingly. A switch can connect the computers via Ethernet port, Fast Ethernet port and optic fibre port. Switch works on its operating software which store the MAC address of devices connected with the various interfaces of switch.
The layer 2 and layer 3 switch are always placed behind the gateway device. Router is generally used as gateway device for all data packets of a network. Layer 2 and Layer 3 switch works like a bridge between the multiple devices in a computer network. Switch are used to the basic data packet forwarding function to high end configuration switching. The latest switch are capable to create and works with VLAN in the network. The broadcast domain can break by creating the VLAN in switches.
All networking devices can be managed with the help of Cisco digital network architecture which is generally known as DNA. The Cisco DNA is fully capable for manage the networking devices by using a GUI dashboard. In case of any change in network topology the DNA system auto detect the new topology and configure the networking devices accordingly.
Cisco digital network architecture DNA manage various applications and services of networking devices. The function of cisco digital network architecture DNA is fully automated. It means any changing in network or miss happening in network will recover automatically. It provides the smooth maintenance of networking devices. Many validation and authentication protocol used by Cisco DNA system for security purpose. The new Cisco DNA centre is an open platform to control the networking devices centrally form a unique device.
Advantages of Cisco Digital Network Architecture DNA
A web browser based dashboard provides control for all networking devices. The dash board is centralized for all the networking devices. Cisco DNA works on basis of policies designed by network administrator. The network policies deploy the networks in very little time. The policies are easy to make and deploy all over the network devices. The Cisco DNA increase the network uptime by implement of policies to all network devices in a very little time.
Services provided by Cisco digital network architecture DNA
The main and most important service provided by Cisco digital network architecture DNA is the centralized management of all networking devices. It is done by a simple dashboard management system. This dashboard of Cisco digital network architecture DNA can manage a thousand numbers of networking devices in a very little time in minutes. The access of devices can be allow to some predefined groups. The member of each group have rights according to the policy to make changes in networking devices.
The intelligence system of Cisco digital network architecture DNA allow automated configuration of networking devices. You do not need to configure the networking devices manually. The automation systems are free from the human errors so we can say this is an error free system.
It became very easy to monitor the condition of networking devices of a network. The networking devices continuously monitored and identified by Cisco digital network architecture DNA. The problem occurred within any networking device can be immediately resolved by the pre-defined policies created by network administrator. The DNA dashboard provides very simple and beautiful preview of network health and monitor the network status.
Cisco Wireless LAN Controller WLC
In addition with the Cisco digital network architecture , Cisco have a different service known as Cisco WLC. Cisco WLC provides the management of LAN devices from wireless central controller. Generally the Wireless LAN Controller manage the Wireless networking devices of the Local Area Network. In addition of management of LAN devices the WLC increase the bandwidth of network.
The working frequency of WLC is similar to Wi-Fi 2.4 Ghz and 5 Ghz. The IEEE standard 802.11 is used for communication between the WLC and LAN devices. The access of WLC with LAN controller is fully secure with some built in security features.
In this article I describe the basics of Cisco DNA and WLC. I hope you found this article helpful. For any query or suggestion you may contact us or drop a comment below. Your suggestions are always welcome by us.
