Sh mac-address command in Cisco RSP4

Hello guys,
Need your ideas on how to know to which port a device connected to using mac-address information on Cisco DLSw RSP4.
I did tried using command "sh mac-address add" but it is not recognized in this IOS.
See below outputs:

Interesting hardware you have there.
Is this perhaps a cat 5xxx with an RSM module?
In that case, the RSM is in fact a router blade.
The command "sh mac-adress " is only found on switches. This info is there already but you need to get it from the supervisor which will be running CatOS.

Nexus 7k is going to be restarted if excute the claer mac address command

Hi all,
We are facing some issues in Nexus 7K.when we excute the clear mac address command,it is going to be restarted.
Could you please suggest me what might be the reason ?
Thanks & Best regards,
Krishna Chintada

I have no experience with Nexus but wondered if you could set the device to reload in 10 like in IOS and then clear the MAC address table. If it didn't restart after clearing the MAC table you could do reload cancel. Although the bigger issue still remains its probably a bug.

Mac Address Tracing - CatOS

I have noticed a lot of bad traffic coming from one particular computer on the network. Normally not a big deal, I found the MAC Address in my DHCP Table, logged into a switch, did a 'sh mac-address-table address <mac address>', found what port it was connected to (it was another switch), I then did a 'sh cdp neighbor detail' got the ip address, telneted to that switch, rinsed and repeated... until I hit a switch that had CatOS.
My question is how do I do this same type of thing on CatOS? I know how to get everything else except which port it is on like the 'sh mac-address-table address <mac address>' command gives me.

just type show cam it will clearly tell where the mac-address is residing.
eg. lets say that 6509--->2950---->(my pc)
in 6509 type show cam
it show some thing like this...
Cat6509> (enable) sh cam 00:02:B3:87:EA:10
* = Static Entry. + = Permanent Entry. # = System Entry. R = Router Entry.
X = Port Security Entry $ = Dot1x Security Entry
VLAN Dest MAC/Route Des [CoS] Destination Ports or VCs / [Protocol Type]
194 00-02-b3-87-ea-10 4/7 [ALL]
on 4/7 2950 is connected, in that again you type the pc mac address.
2950#sh mac-address-table address 00-02-b3-87-ea-10
Mac Address Table
Vlan Mac Address Type Ports
194 0002.b387.ea10 DYNAMIC Fa0/2
Total Mac Addresses for this criterion: 1
which means the pc is connected on fasethernet 0/2 port.
hope this helps,

Configuring Virtual MAC Addresses on ASA

Hello,
I configure the virtual MAC address for a interface on ASA 5520, will enter the following command on the active unit:
failover mac address Inside 0012.3456.789a 0023.4567.89ab
The active MAC address is of the same as the Inside's burned-in MAC address of the active unit.
Similarly, the standby MAC address is of the same as the Inside's burned-in MAC address of the standby unit.
Do I get the effect of failover mac address command?
Thank you for your cooperation in advance.

Hi Bro
That’s fine really. There’s nothing wrong if you’ve configured the active MAC address the same as the Inside's burned-in MAC address of the active unit.
In an Active/Standby failover, the MAC addresses for the primary unit are always associated with the active IP addresses. If the secondary unit boots first and becomes active, it uses the burned-in MAC address for its interfaces. When the primary unit comes online, the secondary unit obtains the MAC addresses from the primary unit. The change can disrupt network traffic.
You can configure virtual MAC addresses for each interface to ensure that the secondary unit uses the correct MAC addresses when it is the active unit, even if it comes online before the primary unit. If you do not specify virtual MAC addresses the failover pair uses the burned-in NIC addresses as the MAC addresses.
P/S: If you think this comment is useful, please do rate them nicely :-)

Obtain MAC Address from 250 iPads

Hi all,
I have taken delivery of 250 iPads which I am configuring with OSX Server on a MAC Mini. So far, so good!
Our wireless network uses MAC Address authentication so I have to add each MAC Address to our Cisco Wireless controller.
Without having to go to Settings > General > About and write down the MAC Address from every device, is there a way to obtain the MAC Address from either the box using the barcode, or maybe an App that loads up on screen and shows the MAC Address of the device in a barcode format that I can then quickly scan into an Excel spreadsheet and import?
I feel that i'm about to waste a lot of time going on to each iPad and obtaining the MAC Address
Thanks in advance
Regards
Jim

If you have the ability to plug them into Apple Configurator, you can connect them with a USB hub and update and supervise them. This will let you export MAC Addresses and Serial numbers from Configurator to a CSV file that you can use to upload to your wireless controller. If you need to, be sure to Unsupervise the iPads when you are done.
The info you're looking for may also be available through GSX, but I'm not familiar with everything you can use it for on your end.

Mac-Address Locking on ML-1000 for the Cisco 15454

Does anyone know if you can do mac-address locking on the ML-1000 card on the Cisco 15454. I would like to enter the command "mac-address-table secure", but it does not look like it is possible to do this.
Thanks,
Eric

The command is not supported on the ML-1000 card.

Cisco Aironet 1240 AG Access Point - configure Mac Address using Telnet

Hi there,
IÂve got a problem hopefully someone can help me with. I have the above mentioned AP and it is configured, working well and providing wireless access to several laptops on our domain.
The thing is I canÂt get access to the web-based interface to add new laptops Mac addresses to the AP as I currently have them secured with local list Mac address authentication but my user name and password when entered in the web browser login dialog box wonÂt allow me in although strangely it does allow me to login using the same credentials when I telnet into the AP.
Does anyone know why I canÂt get logged in using the web interface even though the user name and password does appear to be correct as I can telnet in? Also if you have any suggestions how I could sort this without having to perform the password recovery procedure, as I donÂt want all the config on the AP wiped and want to avoid having the set the whole thing up again.
As I workaround if anyone knows what the commands are to allow me to add the Mac addresses of the new laptops so they are added to the local list Mac address authentication list so the new laptops are secured that would be great.
Thanks in anticipation,
Tony

Your AP is probably configured to use the enable secret as the password. Try entering nothing for the username, and enter your enable secret for the password ('Cisco' by default).
If that doesn't work, post your running-config and we'll be able to see why it's doing that. It's a standard configuration, and no worries because wiping the AP won't be necessary since you can successfully Telnet in.

Cisco wlc2504 mac address filtering

I am using a wlc2504 software version 7.4.100.0. I use MAC filtering for wireless device to connect to our wi-fi. Currently I have about 249 saved MAC address that can access the wi-fi. About once a week, the controller looses or forgets 3-5 MAC addresses, thereby devices looses connectivity to wi-fi. Is there a limit to number of MAC address configured to be saved? What is causing this? What can I do to prevent this from happening? Thanks.

MAC Address Filter (MAC Authentication) on WLCs
When you create a MAC address filter on WLCs, users are granted or denied access to the WLAN network based on the MAC address of the client they use.
There are two types of MAC authentication that are supported on WLCs:
Local MAC authentication
MAC authentication using a RADIUS server
With local MAC authentication, user MAC addresses are stored in a database on the WLC. When a user tries to access the WLAN that is configured for MAC filtering, the client MAC address is validated against the local database on the WLC, and the client is granted access to the WLAN if the authentication is successful.
By default, the WLC local database supports up to 512 user entries.
The local user database is limited to a maximum of 2048 entries. The local database stores entries for these items:
Local management users, which includes lobby ambassadors
Local network users, which includes guest users
MAC filter entries
Exclusion list entries
Access point authorization list entries
Together, all of these types of users cannot exceed the configured database size.
In order to increase the local database, use this command from the CLI:
<Cisco Controller>config database size ?
<count> Enter the maximum number of entries (512-2048)

How to get the MAC address of the additional 10G NIC with ILO command line

how to get the MAC address of the additional 10G NIC with ILO command line?
thanks.
This question was solved.
View Solution.

Hi Bruce,
Out from what I can find on this network card is it not possible to get the mac address without a OS. I would recommend you to get/burn a Linux/Ubuntu live CD/DVD and run a Ifconfig in there.
Hope it helps you.

Mac-Address Different format for Authorization on Cisco ISE

Dear All,
I have problem with my Cisco ISE,
This is the design :
ISE ---- Core Switch ---- 3Com Switch --- PC User
My Case:
Authorization is based on Mac-address and Active Directory,
But user with PC that connect to 3Com swtich is Deny by ISE because the Format Mac-address is different with Cisco,
Mac-address Cisco format : XX:XX:XX:XX:XX:XX
Mac-address 3Com format : XXXX-XXXX-XXXX
3Com Switch type is TRICOM 4210 26-PORT.
Anyone have experience with this? and how change the mac-address format in 3Com so user can authorized by Cisco ISE.
note:
authorization based on Active Directory is not problem with 3Com Switch.
Based on my experience, Different product is different format mac-address, so this case not only for 3Com Switch.
Thanks,
Arika Wahyono

I do not think Cisco will add these vendors to the supported switch matrix because then it would be a support issue that cisco would have to deal with, much like most of the AD issues I experienced when I worked in TAC. Your best bet would be to run the evaluation license instance in a lab and have a 3com switch point against that.
Other than that I do not recommend upgrading to 1.2 without validating that the new "multi-vendor" MAB support will work on your switch.
PS- Keep in mind that my comments is just my opinion so you may need to open a TAC case for an official answer.

Cisco WLC Client MAC address backup to new Controller & ISE

Hi All,
We have an existing 4400 controller with MAC filtering for clients configured. Right Now, we are migrating to 5500 WLC and ISE setup.
We want to use MAC filtering due to company policies on the new Controller as well as ISE.
Is there a way (from GUI/CLI) that we can export the client MAC Addresses into an Excel file from existing WLC to new WLC & ISE?
Thanks,
CJ

On the CLI issue a show macfilter summary and then import that into excel or a text editor.

MAC Address FF:FF:FF:FF:FF:FF on a Cisco 7920

Hi!
Maybe someone of you can help me about my problem. I have my 7920 that can not authenticate to the CallManager and no signal for wireless is detected. When checking the Mac address I could see that it reflects ff:ff:ff:ff:ff:ff
Can this be fixed? How?
Thank you,
Oscar.

Try upgrading the firmware through the Configuration Utility.
