Required for NAC firewall ports manager manage/add the Cisco switch

Hello

I am trying to add switches cisco for the NAM, but I am not able to add the switch I get the error "unable to control switch" I tried opening ports 161-162 on the firwall; If I were to allow all traffic between the NAM and the switch, cisco NAM is able to add/manage the switch.

Do not know what are the other ports may be required for cisco NAM for managing the switch?

Thank you.

Hello

As far as I KNOW, only UDP 161 and 162 for SNMP communication ports must be open.

Please make sure that you have configured the correct port on the switch:

(config)# snmp-server host 172.16.1.61 traps version 2c cam_v2 udp-port 162 mac-notification snmp 

If still does not, I would check the logs on the firewall for any traffic blocked between the cam and the switch.

HTH,

Tiago

  • Required for ESXi firewall ports

    I intend to place a single ESXi host in our DMZ.

    I need to check which ports must be open on the internal firewall to manage this host.  That's what I have so far:

    443 two-way - to access the vsphere client

    two-way 902 and 903 - Access console via vsphere client

    22 - for use with SSH management

    Anything else?

    All I really need is to be able to connect via vsphere client and perform management tasks typicall and view of the virtual machine and SSH remote if necessary consoles.

    Thank you!

    Yes, I think that this will go well. Unless you are already aware, take a look at http://www.vreference.com/firewall-diagram/ for a good overview of the various ports.

  • Cam of the NAC could not add the access switch

    Hi all

    My problem is I can't add the access switch to the cam using mozilla firefox or IE.here attech file cannot add the device. Any idea to solve my problem?

    Hello

    Plese note to add a device (switch) to the CAm, you must go to the leadership of OOB-> appliances-> New.

    First, you must configure the SNMP settings on the switch and the cam so that the cam and the switch can communicate.

    I advise you to make sure that carefully read the configuration for OOB guide and management switch:

    ASA failover partners must have the same number?

    Hereby I guess that you are referring to the same number of interfaces.  These interfaces must also be of the same type.  so you can't have an ASA with 4 interfaces of concert and the other with 2 interfaces Gig.  Or you can, but you will not be able to use the failover for 2 of the interfaces on the SAA with 4 Gig interfaces.  Similarly, if both ASAs have 4 interfaces but an ASA has 4 interfaces Gig while the other has 4 Fastethernet interfaces, then this only would be not supported.

  • Is it possible to have the photograph for $9.99 package and sometimes add the unique program of $29.99 every so often?

    Years, I had the complete package and pay $55 / month. However, my job has changed and I barely use as many programs as I did so I was throwing a lot of money for something I don't need. All I really need is Photoshop, Lightroom and occasionally Flash or AE. It is rare that I use Flash and AE these days but it is launched once in a Blue Moon so I wouldn't cut them completely. I was wondering if it is possible to have 2 plans to go. Have the plan of $9.99 ongoing photography and sometimes add the single $ 29.99 program, when I need one of the other two?

    Also, if I switch my package is the switch without welding or do I need to re - install these programs? I lose information or settings in my current programs of the PS or LR?

    Thanks in advance for the help

    What I want to know and have asked above, is whether it is possible to have both the package being photography (annual plan of $ 9.99 / month) AND add a monthly (monthly plan of $ 29.99 / month) whenever I need for a month here and there.

    In other words... is it possible to have 2 packages running at any given time?

    Yes.

    You can subscribe to the Plan of photography (12 month contract) + unique App (monthly) at the same time on the same Adobe ID. It's going to be two separate monthly fees when you run the monthly Plan of single App too.

    You can pay for the monthly as Plan and when you want for a month at a time to the higher rate than a 12 month contract.

  • Network management - only the virtual switch

    I installed latest ESXi 4 Update 1, which is available. I m running Active Directory LAB on several virtual servers Windows 2008 R2 and one of them acts as a router with RRAS role. I m creating 3 different subnets and one of them must be only virtual - no material connection NIC in the interface of ESXi´s it seems that I can't do this, while creating the new switch virtual it forces me to select NIC it becomes a problem, because if I use a virtual switch for Windows 2008 router has the physical NETWORK map It will come to mean that the cable is disconnected. And I need a virtual connection between virtual servers only, that they will be the single subnet between them and communication to physical clients will go through this router´s of Windows 2008 NIC that is not supposed to be physical.

    How can I archive with ESXi?

    You can create a vSwitch without attached Teddy.

    Do not select any NIC, or delete them after the creation of the vSwitch.

  • The WAN Port is communicating with the Ethernet switch?

    I have a Comcast gateway that the router is disabled in so it acts only as a modem. This is related to an Airport Extreme, which serves as my router via the WAN on the AE port. I created a different WAP with a Capsule temporal from the airport, located downstairs with an Ethernet cable from one of the Ethernet ports on the AE to the WAN on the TC port. I think it's what we call a 'roaming network.

    My question is, can I connect my switch Gigabit 8 ports in one of the Ethernet ports on the TC to complete connections wired to all devices connected on it, or should I first connect EI to the switch 8 ports and then connect the switch to the port WAN TC to complete my network "roaming"? In other words, plug it into the port WAN AE or TC still allows you to use other Ethernet ports as a switch?

    Thank you!

    can I plug my Gigabit 8 ports switch in one of the ports Ethernet on the TC to complete wired connections to all devices connected on it

    Yes, assuming that the TC has been configured to run in Bridge Mode, which would be normal.

    or should I first connect EI to the switch 8 ports and then connect the switch to the TC WAN port to complete my network "roaming"?

    It would be considered preferable to wiring, if it is convenient to do so.  For example, in the configuration of the wiring in the previous example just above... If there is a problem with the time Capsule, then all devices connected to the switch to the time Capsule would have a problem as well.

    If the switch is connected to the AirPort Extreme, and the TC is then connected to the switch... If the TC has a problem, the other devices connected to the switch of will not be affected.

  • Required for controller ethernet and FN - keys to the A100 Satellite drivers XP

    Hello.
    After Reinstalling windows xp, I found almost all of the drivers, I need on this site.
    But I have a camera more...

    Ethernet controller.

    first problem is that there are installed to device:
    Network adapter 1394
    Intel Pro/wireless 3945ABG Network Connection
    so I do not understand what Ethernet controller we talk... is not just a single Ethernet controller "1394 Net adapter" or I do not understand and is not at all controller?

    Secondly - I can't find driver for this device.

    Any ideas?
    Help me to find the driver, please...

    And another problem.
    After you reinstall all work well, but Fn + XX combinations do not work.
    I can't know what I need to install or activate too to make them work...
    Help me know please.

    Hello

    the way to the network adapter 1394 firewire port which, as I know doesn´t need a driver. I don't know, maybe it's also bluetooth, so if it is BT then, you must install a Toshiba bluetooth stack. And it's definitely nothing to do with your ethernet controller. :)

    Regarding your problem of FN: what do you mean this doesn´t work at all? You said that you have the drivers installed so I guess it should work. Maybe reinstall it may be an option (I know it sounds how stupid, but give him a chance, maybe you missed something...).

    Please give some feedback, so that we can chat about it.

  • How to add the physical switch/router to NSX

    Hello

    I check several labs and I have a big question unanswered!

    How can I add physical switch resources to NSX?

    on each of the scenarios, it assumes that you have a few physical interfaces on each host, and you can assign them to a VDS.

    It's good, but it was also available on old vCenter without NSX.

    For example, how can I add switch 24 ports 10 gigabit Ethernet on my Brocade switch to the VMware resource pool?

    Thank you

    You are welcome, of course.

    The network virtualization is not on the ability to win, but it's rather on the use of the available capacity of more flexibly to maintain security between virtual machines without worrying about the port based firewall or port-approaches physical configurations and physics on the VLAN externally in your virtual infrastructure.

    Just as the server virtualization adds capability to your server infrastructure, it allows a more flexible use of the physical capacity that is available.  You must you the capacity available to the involved hypervisors.
