• Errors of run Switchport Port-Security

  So I'm a bit new to switchport security.  I work on most of the ports in one location.  Its ports where I either switchport voice and switchport access VLAN or just switchport voice VLAN.  For some reason, these types of ports going into err - disable.  Here are a few examples.  Indications as to why it would stop even when I have the right MAC address would be very useful. Interface Fa0/3 has a phone attached to it and a connected computer the phone is off.

  The newspaper says this whenever I turn on port security.  Any other port where there is only 1 VLAN or 1 device, it works fine no problem.

  I know I'm missing something because I am new to using switchport security.  I am wanting to lock the ports to prevent devices not allowed to plug in on my network.  I have disabled all DHCP, but I want to take a little further and prevent them to enter the network even and probe the network.

  EDIT - You forgot to mention that it is a 2960 version 15.0 (2) SE5

  Thank you

  David, Kevin,

  Let me join you.

  The way I see the Fa0/2 work with its original configuration is:

  • The maximum number of secure MAC addresses is 1.
  • Access to the VIRTUAL LAN is 1, the voice VLAN is 2.
  • The static safe MAC address 34a8.4ea6.0f95 is added to the access VLAN, not to the voice VLAN
  • When the phone starts to make known by the voice VLAN, MAC address cannot be dynamically added to the list because the maximum allowed number of MAC secure is 1 and the list is already full. The fact that its MAC address is configured statically is irrelevant, because it is not associated with the voice VLAN.

  Try to delete the line

  switchport port-security-address mac 34a8.4ea6.0f95

  and replace with

  voice of vlan switchport port-security-address mac 34a8.4ea6.0f95

  and see if it solves the problem.

• How to access the USB secure key on windows vista, I get the message that application 10004 could not find any JumpDrive Secure device connected to your system

  Original title: how access key USB secure Windows vista

  I have a lexar player sure to jump that I used with an old computer that has Windows XP.  I now have a new computer with Windows Vista and I can't access the secure part of the USB key.  When I try to access the part secure the USB key I have the following message "Application [-10004] could not find any JumpDrive Secure device connected to your system. Please make sure that your JumpDrive Secure device is inserted into a USB port".

  Of course, the USB key is inserted into the USB port.  If anyone can help find me a way to access the part secure the USB key I would appreciate it.  Thank you.

  Hi Jon0909,

  The error that you received can be for several reasons. I suggest you try the following steps:

  Method 1: Run the fixit available in the link below and check if that makes a difference

  Tips for solving problems of USB devices

  Method 2: This normal matter as a result of a conflict between the USB and other USB (Universal Serial Bus) connected to the computer.

  (a) disconnect all the external devices connected to the computer to expect the mouse and keyboard, check if your USB key works.

  (b) If this solves the problem, and then add back both devices until you discover the piece of hardware causing the issue.

  If the problem persists, you can contact the manufacturer of the device for any known issues

• Drive C: locked TPM (security device)

  I tried to restore an image of my drive C: using Macrium Reflect.  Macrium said that the C: drive is locked and he can't find the drive, it finds that the backup USB drive so I can choose the image I want to use for the restore but cannot select where I want the image to put because the C: drive is not found. I have used nto bit locker and the drive is not encrypted.  In all other respects, I can access the C: drive and operate the computer normally (read, write, change etc any file). I also have a pop-up to start up, which said: "there was a problem connecting to the module of TPM (safety device) on this computer.  It is possible that anti virus software or a firewall is blocking the connection.  A disk missing or disabled could cause this problem.  Please refer to the online documentation for more information."  I've disabled the firewall and disabled security of the BIOS chip and have disabled the TPM, but none of these things to solve the problem.

  http://www.Macrium.com/support.asp

  I suggest you might try their support, because it is their product that you have problems with.

  It can be a normal problem with their software.

  Read what is the TPM secure:

  http://support.Dell.com/support/topics/global.aspx/support/DSN/document?c=us&l=en&s=Gen&docid=E75E35123E8AC4D0E030030ABD623A10

  Trusted Platform Module, or TPM module, is a security device that holds the keys generated by computer for encryption. This is a hardware solution which prevents hacking attempts to capture passwords, encryption and other data sensitive keys. The security features provided by the TPM secure are supported internally by

  • Hash
  • Generation of random numbers
  • Asymmetric key generation
  • Asymmetric encryption/decryption

  Each TPM has a unique signature initialized during the process that improves the effectiveness of trust/security of silicon manufacturing. Every TPM must have an owner before it can be used. The user of the TPM secure must be physically present to support. Once this procedure is run and the TPM has a unique owner, the TPM module is enabled.

  See you soon.

• PowerConnect 35XX port security

  Hello. I am trying to locate a CLI command that will allow me quickly clear course MAC addresses for a port secure with port security.

  My configuration of the interface is fairly simple.

  dot1x multiple-host
  dry port max 2
  dry port stop throw

  If I connect to a different host, the original at the port this as it should and travel to port security. Now, everything is fine, if I plan on the reconnection of the original host. Issue the global command "set interface active ethernet eth #" and the port is back online. The problem comes when I want to change the host. I have to completely remove the dot1x and the security configuration of the port [minus the max], 'set active interface' and then add security dot1x port for the interface configuration.

  Is there a way to quickly clean the secure the port addresses so that the new addresses can be learned?

  Thanks in advance.

• switchport port-security problem

  Hi all

  I wanted to test using the switchport port-security with mac address fixed for voip and sticky for the vlan access.
  to do this, I created the following configuration:

  switchport port-security maximum 2
  switchport port-security
  aging of the switchport port security 5
  switchport port-security-address mac sticky
  voice of vlan switchport port-security-address mac e8ba.7006.59a4

  the problem is the mac address that switch learns to access vlan, never goes away even if the device is no longer connected.

  switchport port-security maximum 2
  switchport port-security
  aging of the switchport port security 5
  switchport port-security-address mac sticky
  switchport port-security-address mac c434.6b24.5db9 sticky vlan access
  voice of vlan switchport port-security-address mac e8ba.7006.59a4

  Can you help me?

  This should make them disappear without having to use any statement when the switchport learns a new mac again if his manual, you have to bounce the port as well

  Disable them sticky interface port-security

• Laboratory of port security exercise - do not behave as expected.

  Hello

  I'm working on a CCENT training lab to demonstrate the configuration of port security.

  I have a Catalyst 3550 switch software Cisco's IOS, software of C3550 (C3550-IPSERVICESK9-M), SE Version 12.2 (52), VERSION of the SOFTWARE (fc3). I have two computers connected on ports fa0/1 and fa0/2 with IP addresses of 10.0.0.20/24 and 10.0.0.12/24 respectively. Without active port security, each computer can ping successfully the other.

  As soon as I change the configuration to add port security on fa0/1 I am not able to ping between the two computers, nor can I ping 10.0.0.20 from the console of the switch, but I don't know why! If I delete it again the pings succeed again.

  I expect that the switch must learn the computer connected to fa0/1 MAC and stop if there is subsequently any traffic from another Mac.

  Interestingly, the 'show mac address-table' command shows that the MAC connected to fa0/1 when port security is not enabled. I don't know if this is relevant.

  Can someone help me diagnose what is happening?

  Thank you.

  Do you have any other platform to configure your lab? because it should work ideally and the configuration is fine. However, to complete your lab, you already have workaround...

  I suspect that this question is something related to the hardware you use or due to a BUG.

• Port security and DHCP

  Hi all.

  I have configured the port security in some ports, and I don't think it handles images as it should. the following settings are

  -max: adds the correct number of MAC

  -permanent safe mode

  -throw

  I connect the legitimate devices to determine the maximum number of MACs, the port must learn and then I connect a device with Mac unsafe. I can get an IP address from the DHCP server, but no traffic is being so forward. I think that no legitimate unit should not be able to get an IP address as port security ignores all frames with an unknown source Mac

  Hi Stelios,

  Your configuration seems to be fine. Mine was connected only with the safety of ports and addresses max I put at 1. I see only 1 MAC address sends bootp all other devices connect via the switch on this port send no bootp.

  You could also make the capture of packets using the capabilities mirror port switch and application of wireshark. Devices are perhaps using old known IP addresses...

  Kind regards

• Port for a port security

  Hello everyone.

  IM building a setup where I have a C2960 switch connected to a Cisco AP-1142.

  The switching point and access will be 2 VLANS, one for professional use and the other for guests (internet only).

  So between the switch and the AP I intend to have a trunk dot1q.

  IM afraid that someone who is connected to the guest network (which has a password that anyone can get at the reception) can execute an attack by cam overflow that will overload the switch.

  What feature suggests you that this would prevent?

  Port security will allow you to limit the number of MAC addresses learned on the switchport but it is difficult to implement for a port Access Point because its going to have a lot of MAC address according to the amount of Wifi users.

  How much you expect to connect about?

  You can activate the security of the port and fixed the limit to something like 25 or 50 and combine this with a time of aging then the removed switch learned MAC addresses once they became inactive for X number of seconds.

• My iPad has been removed from secure devices!

  I received an email telling me that my iPad has been removed from my list of secure devices.  Apparently, if I read correctly, because it "has been DELETED."  But my iPad has NOT ERASED!

  I connected to my Apple ID page and restored my iPad to my secure devices.  I use 2 part checking my ID and for awhile, so I see no reason to change my password for Apple, as the email suggested (he recently changed before that), but I AM MISSING SOMETHING?

  Why would this happen?

  Have you checked the full address of the sender to see if it was really Apple or a phishing attempt?
