IEEE User location cannot be predicted as they may be at and out of a desk and up and about should they need to do so. Tying them to a local VLAN may only be helpful if they are bound to desks in those locations, although the most ideal outcome, it is not the most practical.

There are laws in the United States defining what a passenger of an airplane is permitted to bring onboard. With technology, we are faced with the same challenges.

Before allowing and entity to perform certain actions, you must ensure you know who that entity actually is Authentication and if the entity is authorized to perform that action Authorization. Additionally, you need to ensure that accurate records are maintained showing that the action has occurred, so you keep a security log of the events Accounting. The concepts of AAA may be applied to many different aspects of a technology lifecycle.

However, this blog is focused on Secure Network Access, and therefore this blog post will focus on the aspects of AAA related to networking. There are two main AAA types for networking:. Device administration can be very interactive in nature, with the need to authenticate once, but authorize many times during a single administrative session in the command-line of a device.

In other words, different messages may be used for authentication than are used for authorization and accounting. This allowed a Layer-2 authentication protocol to be extended across layer-3 boundaries to a centralized authentication server. Today it is still used in the same way, carrying the authentication traffic from the network device to the authentication server.

With IEEE When the authentication request is sent to a AAA server, the AAA client expects to have the authorization result sent back in reply.

I love the product and I have personally configured it in critical environments to perform both Network Access and Device Administration AAA functions.

Device Administration and Network Access policies are very different in nature. With Device Admin, you are creating a policy that dictates privilege-level, and command-sets i. The network access policy really cares about attributes of the endpoint such as its profile does it look like an iPad, or a windows laptop and posture assessments. Therefore, the policies will always be administered separately, with different policy conditions and very different results.

As a direct extension to the different policies, the reporting will be completely different as well. Network Access reporting is all about who joined the network, how did they authenticate, how long were they on, did they on-board, what types of endpoints are on the network, etc.

Device Admin reports will be about who entered which command and when.

Why would we design this way? Because we certainly don't want a network user, say John Chambers CEO of Cisco Systems trying to logon to his wireless network and the RADIUS server not answering before it times out - due to being so busy crunching data related to "is Aaron allowed to type show?The information in this document was created from the devices in a specific lab environment.

Grouping existing server hosts allows you to select a subset of the configured server hosts and use them for a particular service. Configuring deadtime within a server group allows you to direct AAA traffic to separate groups of servers that have different operational characteristics.

This feature module describes how to configure AAA server groups and the deadtimer. Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release.

A server group is used with a global server-host list. The server group lists the IP addresses of the selected server hosts.

Server groups can also include multiple host entries for the same server, as long as each entry has a unique identifier. If two different host entries on the same RADIUS server are configured for the same service—for example, accounting—the second host entry that is configured acts as a failover backup to the first one. If the first host entry fails to provide accounting services, the network access server tries the second host entry configured on the same device for accounting services.

After you configure a server host with a server name, you can use the deadtime command to configure each server per server group. Configuring deadtime is not limited to a global configuration. A separate timer is attached to each server host in every server group.

Therefore, when a server is found to be unresponsive after numerous retransmissions and timeouts, the server is assumed to be dead. The timers attached to each server host in all server groups are triggered. In essence, the timers are checked and subsequent requests to a server once it is assumed to be dead are directed to alternate timers, if configured.

When the network access server receives a reply from the server, it checks and stops all configured timers if running for that server in all server groups. If the timer has expired, the server to which the timer is attached is assumed to be alive. This becomes the only server that can be tried for later AAA requests using the server groups to which the timer belongs.

Because one server has different timers and might have different deadtime values configured in the server groups, the same server might, in the future, have different states dead and alive at the same time.

To change the state of a server, you must start and stop all configured timers in all server groups. The size of the server group will be slightly increased because of the addition of new timers and the deadtime attribute. The overall impact of the structure depends on the number and size of the server groups and how the servers are shared among server groups in a specific configuration. To define a server host with a server group name, enter the following commands in global configuration mode.

The listed server must exist in global configuration mode. Each server in the group must be defined previously using the radius-server host command. Enter your password if prompted.


Defines the AAA server group with a group name. Local server group deadtime overrides the global configuration. If the deadtime vlaue is omitted from the local server group configuration, it is inherited from the master list. The following example shows how to create server group radgroup1 with three different RADIUS server members, each using the default authentication port and accounting port :.

The following example shows how to create server group radgroup2 with three RADIUS server members, each with the same IP address but with unique authentication and accounting ports:.

The following example shows how to configure the network access server to recognize two different RADIUS server groups.In this series, we will be looking at how to use the Cisco ISE for several purposes.

We will start off small in this first article by configuring the ISE to support user authentication for device administration, e. The old format equivalent is radius-server host The next thing we need to do is configure users on the ISE. The third thing we need to do is configure authentication policies or use the default authentication policies that come with Cisco ISE.

As we will see, Telnet authentication to a router is done using PAP so we can use the default authentication policy. Finally, we need to configure an authorization policy or use the default policy included in Cisco ISE.

As shown above, there are four default authorization policies that come with the Cisco ISE. The first three deal with wireless and IP phones.

The default authorization policy is good enough for us since it permits access. The user was successfully authenticated.

We can view more details by clicking on icon under the Details column. The first part is an overview which shows us that the authentication succeeded and the username and authorization policy that was applied. The next section shows the authentication in detail.

We also see the network device and some network device details like the IP address, the port ID and port type. The third section shows us what authentication and authorization policies were matched. As you can see, it matched the Default for both. There is also a section that shows you the steps that the authentication session went through.

The Steps section can be very useful for troubleshooting. We used the default authentication and authorization policies in the scenario in this article but in the next part of this series, we will create our own policies.

Click Here! Skillset What's this? Now we move on to the configuration on the ISE. Define usernames on the Cisco ISE or an external identity source.AAA allows you to configure local users on the Viptela device. AAA configuration is done in two steps:. The Viptela software provides one standard username, admin. Only a user who is logged is as the admin user is permitted to create additional users. The name cannot contain any uppercase letters.

Some usernames are reserved, so you cannot configure them. For a list of them, see the aaa configuration command. Each username must have a password, and each user is allowed to change their own password. The CLI immediately encrypts the string and never displays a readable version of the password.

When a user is logging in to the Viptela device, they have five chances to enter the correct password. After the fifth incorrect attempt, the user is locked out of the device, and they must wait 15 minutes before attempting to log in again. If an admin user changes the permission of a user by changing their group, and if that user is currently logged in to the device, the user is logged out and must log back in again.

The factory-default password for the admin username is admin. It is strongly recommended that you modify this password the first time you configure a Viptela device. For example:. The Viptela software provides three fixed group names: basicnetadminand operator. The username admin is automatically placed in the netadmin usergroup. The name cannot contain any uppercase letters Some group names are reserved, so you cannot configure them. If a remote server validates authentication and specifies a user group say, X using VSA Viptela-Group-Name, the user is placed into that user group only.

However, if that user is also configured locally and belongs to a user group say, Ythe user is placed into both the groups X and Y. In the task option, list the privilege roles that the group members have.

The role can be one or more of the following: interfacepolicyroutingsecurityand system. In the following example, the basic user group has full access to the system and interface portions of the configuration and operational commands, and the operator user group can use all operational commands but can make no modifications to the configuration:.

You can specify the key as a clear text string up to 32 characters long or as an AES bit encrypted key. The password must match the one used on the server. The priority can be a value from 0 through 7.

A server with a lower priority number is given priority over one with a higher number. By default, the Viptela device uses port for authentication connections to the RADIUS server and port for accounting connections.We are able to view this video without any issue. Would you be able to try on a different browser or computer? Please i need to work on the Cisco ISE and i haven't done anything with this before. Yes, it is just for lab testing and practice. I saw it on this site, if i am not mistaken, The Cisco ISE was installed on a VMware sphere with windows server and some testings were done.

All the hardware you need are an ESXi server and a compatible Cisco switch. You can follow ISE video series on our website for all installation and configuration procedure. All lab diagrams are also available. You will certainly need to have some familarity with Vmware ESXi and concept of For further question, please kindly post them on our forum link below.

As you have instructed, i have learnt the active directory and the I also wish to integrate a free radius server. Do i need to install this also on the ESXi? Secondly in other to test for BYOD, i also wish to install the Cisco virtual wireless controller on the ESXi and have them a connected through the virtual switch in the ESXi to communicated with each other.

Up to now, all your explanations have been very vital. I have a switch and on this witch i have all my configurations entered, except for the Do u see me having issues in using both switches or i should default to just one switch.

We are not familiar with SG hence not sure if it contains all the Rule 2 name Wired-Mab with identities store is Internal Endpoint. The problem is when put Wired-Dot1X to first, everything ok with user use So they authentication faild.

And when i put rule Wired-Mab to first, device use mab method authentication success but user use I find the way out is put rule 1 inside rule 2 or opposite.
