ISE Server - query of multiple networks

Hi guys

We intend to deploy a Cisco ISE server to handle NAC for 300 users (Windows, WYSE, phones Avaya and HP printers). DHCP is running on the domain controller and the ISE interface Layer 2 visibility of all of the network segment management.

We received an additional amount for a dedicated/completely separate switch VLAN which provides unlimited Internet access. It would be connected to a third-party router connected to the Internet, allowing connections directly on the internet. Indeed, it is a completely separate network of a single VLAN and Internet access.

Is it not possible to manage the security of the ports for that VLAN from the ISE Server? If so, the server ISE would need an additional NIC configured in the VIRTUAL Internet LAN subnet?

Basically, I wonder if a single ISE server can be used to manage 2 totally independent networks. The Internet would not use AD authentication and access would have to grant manually on a case by case basis.

Thank you very much

Just to clarify, ISE has NO need to be Layer2-adjacent to clients to work. Only if you use specific profiles of the probes is this useful ever. Has no use when you perform the validation of the mac addresses or 802. 1 x.

As for your question, yes ISE can manage the addresses of mac validation by the ex. say requiring access to your 'Internet' VLAN and your internal VLANS at the same time. However, it is not made with the 'port security' switch feature, but rather by entering the mac addresses that need access to your server to ISE and using the "group" you put them in ISE, in ads a condition when the permission access to ISE.

  • How to configure a VM with multiple network cards to see Agent?

    How to configure a VM with multiple network cards to see Agent?

    We can archive this requirement by configuring the subnet used view Agent.

    The subnet determines which view address of Network Agent provides the server instance to connect to view for the client protocol connections. The view on VM officer has more than one NIC

    Follow the procedure below:

    on a display Agent installed VM,

    * Recording of VM session.

    * RUN--> type regedit or type regedit.exe at the command prompt

    * Create a registry entry to configure the subnet.

    For example: is HKLM\Software\VMware, Inc. \VMware VDM\Node Manager\subnet = n.n.n.n/m type - REG_SZ.

    In this example, n.n.n.n is the TCP/IP subnet, and m is the number of bits in the subnet mask.

  • [Oracle] [ODBC SQL Server driver] [libssclient22] General network error

    I use the oracle gateway (11.1) to sqlserver on Linux platform with the Oracle 10 g server.

    I'm getting following error when I run a select query:

    ORA-28500: connection between ORACLE and a non-Oracle system has sent this message:
    [Oracle] [ODBC SQL Server driver] [libssclient22] General network error. Check your network documentation. [Oracle] [ODBC SQL Server driver] [libssclient22] ConnectionOpen(connect()) (connect()). [Oracle] [ODBC SQL Server driver] Invalid connection string attribute

    Another thing is, I've created an ODBC DSN named "sqlserver" as well. This configuration works well when the parameter "program" dg4odbc in Listener.ora. But with dg4msql, it gives an error.

    Here are the configuration files:

    Hello

    The error you are getting is because your HS_FDS_CONNECT_STRING is not correct:
    Don't forget you can ping the SQL SERVER name of the Oracle server command, or use the TCP/IP address
    Check the port, it is not necessary 1433.
    You can use the name of the instance instead of the port:
    HS_FDS_CONNECT_STRING = server_ip_address/instance_name/database_name

    Be careful, in the LISTENER. ORA, you must specify the gateway machine and not the SQL SERVER machine:
    SqlServer =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP) (HOST = Gateway_Machine)(PORT = 1522))<====you must="" specify="" oracle="" gateway="">

  • ISE server receives requests for authentication of the bridge VLAN, not the IP Address of the switch management

    Hello

    A 3850 catalyst switch has VLAN 20 (10.18.4.32/29) defined on it, which has a 10.18.4.38 gateway:

    D01-01-BWY #show ip short int vlan 20
    Interface IP-Address OK? Method State Protocol
    Vlan20 10.18.4.38 YES manual up up

    A server of ISE (SNS3415) is connected to a port configured on VLAN 20, with IP address of 10.18.4.33.

    01-BWY-D01 has to a management interface of 10.18.4.17.

    I created this switch as a device network in ISE and activated the RADIUS config and then configured the switch with the following commands:

    RADIUS attribute 6 sur-pour-login-auth server

    The problem:

    When I test the functionality of RADIUS using the following command, it fails. HOWEVER, the customer (switch) IP listed in the error log in the front door of the VLAN 20 (!):

    test the aaa group RADIUS server 10.18.4.33 auth-port 1812 Capita123 user radius acct-port 1813! new-code

    10.18.4.38 is the gateway IP address of the VLAN that hosts the servers of the ISE, I don't understand why its listed in error as IP device logs!

    can someone clarify the situation what is happening here?

    I need to be able to define multiple switches by their unique IP addresses.

    Hello

    The only time I saw that it was due to use a deprecated command: radius server host.  There was a bug on the IOS XR platform as well.

    Could you please reconfigure your order of RADIUS by using the new command: radius server? And test again?

  • ISE-guest user account multiple connections

    Hello

    How do ISE I only allow a connection to the guest both user account.    the real problem I have is when I give a username invited to someone, it can circulate this userid with others and multiple unauthorized guests use this unique user id to connect to the portal comments

    In any case restrict?

    Limiting the guests at a Session active network

    You can restrict the guests to have a single device connected to the network at a time. When clients try to connect with another device, the device is automatically disconnected from the network.

    It is a global setting that affects all the portals comments.

    Step 1 choose Administration > management Web portal > settings > comments > political portal.

    Step 2 check the only guest session authorized by user option.

    Step 3 click Save.

  • vCenter - multiple network cards

    Hello

    I have a vCenter Server 4 U4 with multiple NICs for managing esxi connectivity etc. All ESXi hosts are connected via a dedicated card. For security reasons I must add one host to vCenter managed on one vlan separated / network card. Is this a supported configuration or a configuration that someone uses?

    When I add the host to vCenter it disconnects after about 60 to 90 seconds. All firewall ports are open and nothing is denied, DNS works very well, as well as the ICMP between vCenter server and the host. Any ideas?

    Thank you

  • implementation of the Hosts file on the server for the entire network?

    I see a lot of information on how to edit the local Hosts file on individual computers. But, is it possible to edit a Hosts file and have effect throughout the network?

    We have a network of a little over half a dozen of Mac mini, who take their DNS information from another Mac Mini running the application server OSX (under El Capitan). This server is the primary DNS machine for the network. I want to implement a Hosts file for the entire network.

    Parental control seems to be broken in OSX El Capitan, so this seems like the best next to us, short option to buy some third-party service, which I prefer not to do.

    I think that dnsmasq installation on your Mac server and configuration of all your computers to use as your "DNS Server" will achieve what you want.

  • RVL200 and Windows 2000 Server - can not access network resources via VPN

    I am new to the VPN, and I feel I'm missing something very basic in my configuration. I just installed a RVL200 as the gateway for my corporate network router.  The network includes a Windows 2000 Server that acts as server DHCP and several PC and a printer.  I was able to "establish a SSL VPN tunnel" home connection to the router, but after recording in everything I see is the screen of virtual Passage - one with lock icons - otherwise I am inside the router.  The statement shows that I am connected.  Once the tunnel is established, what am I supposed to do to get computers to the computers on my network?  I can ping all computers on the network using their LAN address.  I'm supposed to see a choice of network resources to get to this point?  I put the router as a trusted site in the server and even tried to disable all firewalls, but I see that the VPN screen with icons.  I don't know how to proceed from here because I don't know what I'm supposed to see.  Thanks for any help that you can give to a newbie!

    The SSL connection is only for the VPN router. To access the computer, you can use Windows Remote Desktop connection. So that you can access to remote computers on the network, or you could look for 3 third-party software for remote access

    Hope this helps

  • Merge devices with multiple network interfaces

    Hello

    Is it possible to add several interfaces to a device network, but merged into a single device?

    For example, we have a lot of HP and Dell servers that have usually a network interface and an interface of management (ILO or iDRAC).

    It would be useful to be able to add two interfaces while having them mapped on the same server in NMS. The network interface would show us the availability on the network and the management interface may alert us hardware problems via SNMP.

    Anyone knows if this is possible, or do we need to have more than one entry for each server?

    Thanks in advance

    Ewan

    Hi Ewan,

    If the INVESTIGATION period is not recognized by the operating system, we most likely would not be able to draw the individual IP addresses of the ILO or the iDRAC. You can present this as a feature request in the ideas of the community section.

    Thank you

  • connections of RAW socket to the server inside the corporate network

    Hello!

    I have not found any documentation anywhere elsewhere I hope someone can help out me.

    o know for ftp/http there are a proxy that is used in the scope of work to access the servers inside the corporate network.

    But what is the best practice for an application installed on the perimeter of work to establish a raw socket connection to access network resources other than http/ftp behind my corporate firewall? so I want something like

    sock int = socket (AF_INET, SOCK_STREAM, 0);

    Connect (...) //using a host/ip within my company and port 1234

    Write (...)

    Close (sock)

    is this possible?

    and second: will it work if I use QTCPSocket?

    Hello.

    Yes, there is a recommended approach to do this for the current version of BES.  A HTTP proxy is used to connect to both corporate and external networks internal when in the scope of work.  To connect to a particular host and port, you HTTP CONNECT request to the proxy, and then once the connection is established, you have a connection with the remote server socket.  I wrote a sample application that covers the QTcpSocket / QSslSocket, BSD sockets, OpenSSL taken and connections of curvature (the species is supposed to be transparent, but there has been problems reported with some built OS).

    I'll clean up this sample application and submit for review before it is posted on GitHub.  If your need is urgent, I could share a few code snippets to help you to implement the solution for your specific use case.
