  Mobility Master Redundancy - Part 1 Mobility Master will be the Main component that can manage Multiple controllers together. The redundancy of the mobility master should be highly considered when it is coming to enterprise wireless networks. Today we are going to see how we can configure the redundancy between mobility Masters Configuring VRRP Those are the main steps that need to follow the configure the VRRP you have to do the same configuration in the other Mobility Master also Some valuable commands to do the troubleshooting the VRRP mention below Show VRRP summary This command will show you how many VRRP instances are configured in the mobility Master Show VRRP This will show the status of the vrrp instances and summary details of the vrrp like IP, MAC, State, Priority etc Show VRRP stats all This will provide the status details of the VRRP  In the Next Part Lets check What kind of Issues normally happen when we are configuring Mobility Master and How to troubleshoot t...

  ARUBA MULTIZONE Aruba Mutizone is the feature that we can use to isolate Guest user traffic from Corporate Network, But this Feature is not only for Guest Network. To use Multizone Feature in Aruba Controller you need Mobility Master based solution.  Key Points in Multizone Multizone gives you separate Management and data Traffic Zones  Primary Zone is the AP connecting Zone when the AP Initial Boot up and also PZ have the Full Control of the AP ( WLAN,RF, etc) MultiZone AP can belong to only one PZ and it can support up to 4 DZ  Maximum 12 Controller for all Zones Maximum 16 VAP per radio for all Zones  Multizone required RFP license  DZ AP Group should be same as PZ ap group Multizone AP Function Flow  CPSec is Highly recommend to enable previous version of  Aruba Controllers does not support Auto-cert provision Feature but now a days Aruba firmware support this so you do not need to manually provision the AP Data Zone does not Required a...

  CHECK ARUBA CLEARPASS SERIAL NUMBER Today we are Going to learn how to check the serial number of a Aruba Clearpass this is useful because you need this to submit license and also if you raise a support ticket they ask the serial number of your CPPM. below i mention the steps  1. log into your ClearPass appliance using WebUI 2. In the Dashboard click on OS version of Clearpass 3. in the Dialog box you can find the serial number  Thanks!!!! Lets meet with another blog        

We need to Integrate Active Directory with ClearPass when we doing EAP-PEAP authentication otherwise if we using EAP-TLS its not need to add AD server to Clearpass Go to Server Configuration and then select your Clearpass Server from the list and then Select Join AD Domian   Then Filled the AD server Information and in here it needs AD server Administrator User name and Password   Now we Success fully add the AD server to Clearpass now we I ll configure the AD server as a Authentication Source for the Clearpass For that Go to Authentication ---- Source   and click Add   Give the name for the Clearpass and select type as a Active Directory from the drop down list  In the Primary Tab you have to give the information of your clearpass server in here you need a service type account for bind DN this is used for read the directory attributes from the AD server   In the attribute click edit and modify tab and from here you can def...

                        In today’s Network Administrators face Huge challenge to manage Guest Access, Corporate Access, IoT devices and BYOD. Aruba ClearPass Appliance is the Tool that will help you to manage Those things in your network. ClearPass will work as a Network Access Control in the Network (NAC). ClearPass Use Cases * Unified Access From Centralized Location you can manage all of your policies of your Network, no need to configure from your edge switch side * Guest Access Solution ClearPass has variety of method to manage guest users they have tools for the manage guest * BYOD Solution ClearPass maintain highly secure TLS method for BYOD solution, they have Personal BYOD portal that users can register their devices * Non AAA Access For manage IoT devices we can use ClearPass the devices that don’t have any authentication method we can use ClearPass Profiler option to profile that device for correc...

How to Configure Spanning Tree root bridge Hi Today we going to talk about how to configure STP Root bridge, Root bridge election is happening with the switchers in the network, To become a root there should be some qualification among switchers, they are, bridge priority Lowest MAC  default bridge priority is  32769   this is tie among switchers then root elect using lowest MAC to change default root configure switch like below Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)# Switch(config)# Switch(config)# Switch(config)# Switch(config)# Switch(config)# Switch(config)#sp Switch(config)#spanning-tree vl Switch(config)#spanning-tree vlan 1 ? priority Set the bridge priority for the spanning tree root Configure switch as root <cr> Switch(config)#spanning-tree vlan 1 ro Switch(config)#spanning-tree vlan 1 root ? primary Configure this switch as ...

Spanning Tree Protocol (STP)                                    Hi After some brake today I gone to talk about spanning tree protocol or STP, When the network expand we need some redundant connection from switch to switch because of stop network fail.                  When we deal with redundant connection It automatically create loops. As a result of loops our network create broadcast storms .                                             To prevent this we use STP. when we talking about STP we need to look at various features like  Root port Designated port Block port Bridge Priority   etc... STP is huge section in Networking from today we'll learn about this STP. My next lesson is how to identify th...

INTRODUCTION  Previously I post some about Network theory. I thought that wasn't good because every sites post of them. After i done my CCNA exam i moved to aruba exams but there are lack of resources. so i think to share my aruba knowledge with you and also help you to pass the aruba exams too.  In here i share practical things that help for passing your exam . because in aruba they don't have any simulation software like cisco packet racer. so keep in touch with me. book marked my site ( Ctrl + D).  Inform your friends about this and also share this.  Thanks

Star, Mesh, Hybrid Topologies Simply star, mesh and hybrid topologies describe how devices plug into each other. In your office how your switchers are connect to each other. Mesh topologies In this topology we can reduce latency and also we have redundancy inside our network. When you have full mesh you have ultimate number of options to reach to location. But in this topology you have to care about cost. Hybrid topologies In this topology every this connect to every thing in the network. You have high level redundancy. But switchers do broadcasting between the networks when it happen broadcast massage flow through the network. So prevent that introduce STP (Spanning Tree Protocol – we’ll discussed it in future.) temporally stop one redundant link. In this topology network automatically become a complex one Star Topology This topology is cost effective. If some device doesn’t need to talk to someone in the network this topology is the b...

About Computer Network A  computer network , or  data network , is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes (data links.) These data links are established over cable media such as wires or optic cables, or wireless media such as WiFi. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other mor...
