Cannot determine MAC address of connected Access Point using Access Connections version 5

I recently installed the newst version of Access Connections (version 5) and discovered I am unable to determine the MAC address of the connected access point. The 'Graphical' screen shows the SSID, IP address of client etc - but does not show the MAC address of the access point. The 'Details' screen shows the MAC address of the access points - but the radial button on the left does not indicate the cfurrently associated access point.

Is it the switch where the node is directly connected ?
Is the NIC at node side, working fine ?
Another fact to consider is, a mac will wipe itself out after the MAC-age timeout.

SG200-08 Loosing MAC addresses of connected devices

I have a SG200-08 Switch that has in the last month been acting up with certain types of traffic. On June 7, 2013 I installed the 1.0.6.2 firmware upgrading from 1.0.5.1. Updating the firmware has not helped.
Last week Tuesday a server that was connected to that switch disappeared from the network, looking at the trouble I had to reboot the server and traffic began to flow. After rebooting the server I found only 1 of 2 MAC addresses from the 1 NIC showing up on the port.
Today I have a Xerox Workcenter connected to the switch on another port and while working on changing settings on the device I stopping being able to reach the device, could not even ping it. I went into the switch port showed active, but no MAC address found in the dynamic table for that port. After rebooting the switch I could reach the Xerox again.
I rebooted the switch on Friday near the end of the day and it was doing better till this morning, all MAC addresses for connected devices were showing up OK. Is the device defective? It had been working OK previously, it is connected to another switch on port 1, and that shows a proper table of dynamic MAC addresses. In both cases of loosing a device it was being used not dormant or in any kind of low power mode.

Dear Michael,
Thank you for reaching Small Business Support Community.
Based on the symptoms; SG200 working fine before, it seems to work ok after reboot, and latest firmware already installed. It seems to me like a hardware failure but still, in order to confirm, it would be a good idea to restore to factory conditions and configure it manually again. Just in case that does not help I suggest you to contact the Small Business Support Center for further assistance;

Please let me know if there is anything I can assist you with in the meantime.

Capturing MAC Addresses from an Access Point AP1131 with SNMP

Hi!
I'm trying to use SNMP to track information as to whats connected to
our access points. The purpose is basic security and auditing in case
of a problem ( virus, technical problem, etc ). We're already able to
capture what wired devices are connected, but not the MAC addresses of
the wireless clients.
We're employing Cisco Aironet APs 1131, and looking around the MIBs, I found
one object that has what I want, but it's not accessible.
cDot11ClientAddress OBJECT-TYPE
SYNTAX MacAddress
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The MAC address of the client."
::= { cDot11ClientConfigInfoEntry 1 }
Does any one know another way to get this information via SNMP?
Thanks U by advance!

WRT610N: Cannot enter MAC address in MAC address filter list

My WRT610N cannot accept a very specific MAC address in any position of the MAC address filter list. It is a valid address and it was working fine in the filter list of my WRT54G but the 610N will just not take that specific address! What is this all about?
Solved!

There is nothing like a "non-critial setup". It's enough to drive by with a car and within a few minutes your network is hacked. Or it's the bored teenager next door...
I recommend to replace the WEP only device instead of taking the risk of a hacked network.
And just forget about the wireless mac address filter. Anyone, who wants to crack your WEP network will collect enough accepted MAC addresses during the cracking process. It's just not worth the trouble to set up the filter and keep the list current...
Thanks for the diligent follow-up gv but I can't replace the WEP-only device for now. (I need to go through a conversion process for that device to accept WAP and that will take a fair amount of time) I understand your point about getting accepted MAC addresses but, at least, it requires a bit more effort... Maybe I will return the WRT610 and stick with my old WRT54 until the 610 gets fixed...

Allowing only a list of mac addresses to connect to the internet?

Hi,
I'm setting up a solution, where access to wireless internet is granted only to a list of mac addresses. It seems MAB security is what I am after. However, before mac address is allowed internet access, I want a user to go through an external and controller-independable registration page.
Consider this flow:
Clientconnects to WLAN, since it's mac address is not allowed, the user is redirected to an external website (http://registration.com, aspx website). Here I ask the user to register an account. Using ip address from the request, I send a CLI command to the WLC controller and learn client's mac address from arp table. Here I need to run another CLI command to add the mac address to the mac database, and inform the user they can access the web.
Few struggles that I'm having now:
1) How to setup web MAB authentication, that, upon failure, redirects the user to an external website?
2) How can I add (white-list?) a mac address to enable it access to the internet?

It seems I should be able to do this, can anyone elaborate?
1) Layer-2 set to Mac filtering only
2) Upon success - user is granted access
3) Upon failure, falls back to Extrenal Web Auth, which redirects the user to my custom web page
4) Upon registering, I make a postback to the action_url
5) User is authenticated? Is there a way to reset authentication sequence at step 4? I don't really want to register the user. During step 4, I'm sending user's mac address back to WLC via SSH. Since mac address will be present on the WLC after step 4, I would like it to just grant access to the mac address, rather than register the user.

Cannot enter MAC Address into Filter Settings for WAP4410N.

When I do ipconfig /all to pull up its MAC address, I see it starts with 8C:60:XX:XX:XX:XX. When I try to add it to the 4th entry of my Client List on the AP4410N, it rejects it with a dialog box:
"MAC 4 must be 12 Hex chars (0~9 and A~F) with optional delimiters (: or -), and the second bit is not a odd number."
I checked over and over that the Wireless Card MAC address is correct and this is the first time I noticed a MAC address card starting with anything but 00. Any ideas what I can do?
THanks.

Hi Nicolas,
I see, since I have the first 2-bit of the wireless adapter with 8C..I will just change to 80? is that what you mean?
Yes I'm sure iI can add that address to the list, but does it mean that my wireless adapter with 8C is the same with 80 and able to connect to wireless?
Thanks
Erik

MAC address and router access control

My iPhone 3GS can only access the network (through my Netgear KWGR614 wireless router) when the router's MAC address access control is off. When I turn it on the phone is blocked. The MAC address I use is taken from the iPhone settings. It begins with 64. All other MAC addresses I have ever seen begins with 00. Is this MAC address correct? If it is right, could it be that the router can't handle this address?

The first 3 bytes of the mac address identifies the manufacturer. For example, mine starts with 04:1e:64 which is Apple
04-1E-64 (hex) Apple, Inc
041E64 (base 16) Apple, Inc
1 Infinite Loop
Cupertino CA 95014
UNITED STATES
. if it starts with 64 then it belongs to
64-4F-74 (hex) LENUS Co., Ltd.
644F74 (base 16) LENUS Co., Ltd.
18-5 Gwacheon-Dong
Gwacheon Gyeonggi-Do 427-060
KOREA, REPUBLIC OF
check this list : http://standards.ieee.org/regauth/oui/index.shtml
enter your first 3 numbers (first 3 pairs) from your wifi (settings/general/about) (don't use colons in the search)
Not sure about the router as I never tried mac filtering. Each router will behave differently.
Hope this helps.

Old Mac address neede to access Time Machine to restore

Replaced HD, now don't remember old mac address to access Time machine. Where is the old address located?

replacing a hard drive does not change the MAC address. if all you did was repalce a drive you can do [full system restore from TM|http://docs.info.apple.com/article.html?path=Mac/10.5/en/15216.html]. this will also allow you to continue using existing TM backups. alternatively, you can use Migration Assistant as already mentioned.

Get-SCVirtualNetworkAdapter-VM$VMName|SelectMACAddress
$ShowMacAddress.MACAddress
But if I go into the SCVMM Management console, and right click on my newly created machine and click refresh, my Mac Address suddenly shows up.
I have tried this link, but it does not work for me

If you are trying to get this information immediately after the VM creation, VMM may not have the information. To my understanding, once the VM is created and the VMM get the updates while refreshing the VM, these updates will get updated.
As a workaround, you could initiate a refresh immediately after the VM creation and then query the MAC.
Refresh-VM VMName
After a successful refresh, you should be able to query the mac address.

Primary N7k cannot query MAC address table

I try:
show mac address-table
show mac address-table <anything else>
The command just hangs on:
#sh mac address-table
Legend:
        * - primary entry, G - Gateway MAC, (R) - Routed MAC
        age - seconds since last seen,+ - primary entry using vPC Peer-Link
   VLAN     MAC Address      Type      age     Secure NTFY    Ports
------------+-----------------------+-------------+---------+-----------+--------+------------------
The secondary N7k does not have this issue.

Do you have a redundant/backup supervisor engine in the N7K?
If so, try to failover to it - I have had instances where the MAC address for a specific host has become "stuck" in one supervisor engine, and the only solution was to failover to the second engine and restart the first.
If you don't have a redundant engine, you may have to restart your supervisor engine with the "reload module x" command, or by simply restarting the switch. Note that if you've only got one supervisor module and you reload it, you will lose traffic while it reboots.
