3850 stack member has no mac address.

I have a strange issue where a member in my 3850 stack has no mac address.  This occurred after at duplicate address was discovered on the management interface.  We have reboot the switch but no luck. still the same. see below:

It's not "strange".  It's a normal behaviour because the 2nd stack member hasn't joined the stack yet.  It could be the that the 2nd stack member isn't powered up or it's not cabled properly.

  • I have a Linksys WRT54G wireless router that has a MAC address

    A month ago, I could print from my PC and my Mac to my Epson printer over my Linksys WRT54G wireless network.  Now, for some reason, I cannot connect and print from either computer.  An Epson tech asked me to check the MAC address of the Mac and the printer to see if they were the same.  They were not.  He then opined that might be why I couldn't print.
    I don't know what changed a month or so ago or why it changed.  I have not done anything to change the MAC address on either the MAC or the printer.
    The Epson guy said the problem might be fixed by adding my printer's MAC address to my router's MAC address.  Something about "enabling MAC address filtering".  Then he told me that was an issue to pursue with my router manufacturer.  Naturally.
    Speaking of that problem...someone else had it, too...another technician at another site wrote: "...by default, routers don't come with mac address filtering enabled...and if that's the case....then adding the printer's MAC will not solve any issue that you may be having..." 
    So, three qustions:
    (1)  Can I add my Epson Workforce 545 printer's MAC address to my Linksys router?  Is that possible? 
    (2)  If I can do it, how do I do it?  I saw no "add" or "edit" functions on the Linksys WRT54G Status Page.
    (3)  What causes MAC address mismatching to happen?   What is unstable in that assembly?
    Solved!

    Mac addresses with different devices will differ. No two devices will have the same mac address. this is also called the hardware address. This is designed so that it will serve as a unique identifier of your devices in the network which you can check thru the router. Now it is possible that wireless mac filter might be blocking it from connecting to the network. But it would be best to check as well and make sure that the printer is connected to your network and has the same ip address segment as your router.

  • Hosts no longer obtaining ip address on switch in 3850 stack

    I have a six switch 3850 stack that has been in production for over a month now, and everything is running normal.  Last week, hosts plugged into one of the switches stopped working, the hosts are not getting an IP address (this is access layer so PC's and phones).  In addition, if I look at the MAC address table for a port, I am not seeing a MAC  address.
    All of them are running 03.03.03SE        cat3k_caa-universalk9 .
    I am thinking this is hardware related, only because on occasion I see the following messages in the logs:
    Dec 17 12:21:18.052: %IOSXE-3-PLATFORM: MEMBER: 5 process fed: : -Traceback=1#88b11e4e26f5ac75f4f2f18f023e5220   :550E7000+3B9240 ngwcutils:2AF2C000+BE94 ngwcutils:2AF2C000+DA9C pthread:2E3C2000+5DC8
    Also, I have a phone in a port on this switch for troubleshooting.  When I removed the service-policy from the port to rebuild the port configuration, I received this message:
    %FED_QOS_ERRMSG-3-QUEUE_BUFFER_HW_ERROR: MEMBER: 5 fed:  Failed to allocate buffers for Gi5/0/1: code 18.

    It could also be a software issue (bug).  Open a ticket with TAC and send them the logs so they can help you resolve the issue.

  • I want to reserve a static IP address on my Airport extreme.  What is the difference between reserving by MAC Address and DHCP Client ID?

    I want to understand the differences in the way you can reserve a static address for a device on the network.  I had previously set the device itself to an address and then reserved it with DHCP Client ID, which I thought was just the devices static addresss.  I'm not sure if this was in fact correct or just happend to work.  I know what a MAC address is, but I'm not really sure what the DHCP Client ID is. So it would be great if someone could clarify it, and the difference between reserving address by MAC Address or DHCP Client ID.

    A MAC address is a unique identification consisting of letters and numbers in a form that looks like this:
    xx:xx:xx:xx:xx:xx
    Every network device has a MAC address, which can be found on a label on the bottom or back of the device. Apple calls this the Ethernet ID.
    A DHCP Client ID is an optional name that you can assign to a device. For example, on your Mac....
    Open System Preferences (gear icon on the dock)
    Open Network
    Click on Ethernet
    Click Advanced at the lower right
    You may be able to edit the DHCP Client  ID here....for example.....you could enter MJ500's MacBook in the space provided. That would be the Client ID of your Mac.

  • Changing MAC address on wrt300n

    So what did I learn today ... never let your little brother on your PC when logged in at a forum ! Result = kicked out, profile deleted, IP banned !
    So I gather that my ISP has only static IP's and they suggest to change my MAC address to get a new IP so I can return to the forum and sign up again with a new profile. So the question is ... how the heck do I change the MAC address on the router ? Anyone have a source that I can read up on this ? This is all very new to me.
    Thanks in advance.

    MAC addresses are like DNA. There are no two matching ANYWHERE in the world (each device in the world has a unique hexidecimal MAC address and no two are alike). Therefore you cannot change your MAC address.
    What I can tell you is what your ISP really means. When you connect your router (which has a MAC address) to their modem, their modem memorizes your devices MAC address and assigns it an IP address. You need to make the modem forget this MAC to get a new IP. 
    To do this, turn off your modem and old router and leave it off for a bit (10 min). Borrow someone elses router (or if you have an old router, use it). Connect it. Turn on modem and new router. Leave on for about 15 min so that your ISP forgets the old MAC address of your original router and creates a new IP address under the new MAC address of the newly connected router.
    After 15 min, power them both down again, disconnect the temp router and connect your original router. Power them back up and wait 15 min again. You *should* get a new static IP from your ISP as it thinks it's a new MAC again. The ISP doesn't remember MAC addresses, only their modem does and once it forgets, it should give you a new IP when you connect the router again.
    Hope this helps!!

  • ISP blocks my APBS due to various MAC addresses used by the router

    Hi all,
    My Internet provider limits access to Internet over Ethernet cable
    for fixed MAC address(s). That means, I have to inform ISP of the
    only MAC address I'll use to transfer data. In the case ISP detects
    traffic with other MAC addresses on my cable, he blocks any traffic
    at all (until cable unplugged and kind of 30secs are waited).
    My configuration is APBS GigaN with "shared public IP" and with
    MacBookPro connected over embedded WiFi AirPort N card.
    I reported EthernetID of my APBS to ISP, but stuck into the problem
    that all the time router is blocked. It successfully receives
    IP settings from DHCP of provider, and then passes nothing in/out.
    The provider said he can see the packets with different MAC addresses,
    as I understood these MACs are exactly AirportID and EthernetID of
    APBS. Why is it happening so, when "shared public IP" with DHCP
    and NAT are selected? Why MAC address of wireless card of APBS is
    visible to outside? What can I do with it, supposing that provider
    can't fix the case on his side?

    Strim

    kevj is right, Your linksys router has 3 MAC address and they all are assocciated with each other.

  • Airport MAC address not set at factory?

    I just received my new MacBook Pro and was getting ready to set my router so that DHCP requests from the new Macbook Pro would receive the same IP address on my home LAN.
    The IP address for the Airport in my new machine is: 00:11:22:33:44:55 as determined by the following terminal command.
    macbookpro:~ pderby$ ifconfig en1 | grep ether
    ether 00:11:22:33:44:55
    I tried to "spoof" the address with this command:
    sudo ifconfig en1 lladdr 00:19:e3:d8:f5:07
    which does not throw an error, but does not work.
    Anyone else get a MacBook Pro where the MAC address for the airport was not set?
    Any ideas on what to do?
    I suppose I can just tell my router the MAC address is 00:11:22:33:44:55

    Of course the MAC address and the IP address are two different things. I'm not sure why, Kappy, you thought I had this confusion. And I beg to differ, but MAC addresses are by interface, not by machine. So the ethernet port has a different MAC address than the Airport. They HAVE to have different MAC addresses or using two IP connections at the same time will not work when both ports are active at the same time and have the same MAC address. Using both ports at the same time with two independent IP addresses is completely supported by BSD Unix as well as OS X.
    On my new machine the Ethernet Port EN0, has the MAC address 00:23:32:c8:27:4a
    On my new machine the Airport Port, EN1, has the MAC address 00:11:22:33:44:55
    I've had a lot of Macs, and this is the first time I've had an airport with this "default" MAC address.
    My question is 1) does anyone else have a MAC address of 00:11:22:33:44:55 on their new MacBook Pro for the Airport hardware? If so, is this correct? Usually the MAC address has a manufacturer's Id embedded followed by a unique ID. 2) If someone is in the same situation have you talked to Apple about this? What did they have to say?
    I can spoof the MAC address temporarily via the terminal, but it will reset to the hardware address on reboot.

  • Where do i find the MAC address on my Airport Extreme?

    Where do i find the MAC address on my Airport Extreme?

    Your AirPort Extreme has two MAC addresses, one for Wi-Fi, which is called the AirPort ID and another for the wired connection, called the Ethernet ID
    Open Macintosh HD > Applications > Utilities > AirPort Utility
    Click Manual Setup
    (Here, I am assuming that you are using AirPort Utility 5.6 for Mac OS X Lion )
    The AirPort and Ethernet IDs are on the summary page

  • Script Automation of VM in SCVMM 2012 R2 Rollup 1 - Cannot retrieve Mac Address

    Hi All.
    I am creating a script for automation of VM
    I have run into a problem, I get my vm created as it should( at least I think so) I can boot the machine and in there I see a MAC Address from the console view, I know the machine has a mac address.
    I have tried to get my mac address like this, the result is blank
    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.

    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.

  • BE 5K CUCM and CUC Mac-Address registering license

    Hi All,
    I am really confused for registering CUC license to which mac-address. (CUCM or CUC)
    I have CUCM be 5k on Server 7828 both CUCM and CUC is installed on same server. For CUCM i got the mac address from show status, but how about registering the license to CUC it should be registered on same CUCM Mac address or CUC has different mac-address.
    I uploaded the licenses in CUCM and need to upload the license in CUC.
    Thank you all in advance.

  • "failed to get MAC address for machine"

    here is the jist of things.
    installed leopard and have it pimped out to my personal specs. I like where everything is and how things are working. No issues. just so you know, i only use WIFI for internet, i share with the guys upstairs. In order to get wifi on my machine, i use a USB dongle. works great no issues with it ever, well until i physically broke it. No big deal. So i replaced it with another one, different drivers/chipset worked.. And since i installed leopard i only backed it up once with TM, i dont care for daily/hrly backups, weekly is fine for me. Now after 2 weeks and a new usb network card. TM gives me an error. i click on the little red i and it says "the backup volume could not be found" so googled and searched the forums not much help, so i tried and formated my ext drive repaired and click on TM again, same error. In the error log in console, right after i turn on TM i get this error, "failed to get MAC address for machine" then 180 secs later, TM fails. again, and again.
    Can anyone tell me where i can find what MAC address its looking for??? ethernet has never been plugged in to my machine ever. its only been online via USB wifi. Im really lost here, i dont know what i can do.. im sure if i try another drive ill get the same error. please help if you can.. much appriciated.
    Jamie

    yeah i get a 'failed to get mac address' message too. what's weird is that it seems that leopard 'broke' my ethernet (there was no mac address, couldn't connect to the internet through ethernet after a clean install), and then 10.5.2 'fixed' it. for some reason, i have an 'ethernet 2' heading in system preferences that works correctly and has a mac address and everything, while the regular 'ethernet' tab doesn't work at all. however, i still get this time machine error. i don't understand why time machine is so incredibly fickle. sorry, i'm really of no help to anyone, other than adding another voice to the frustration.

  • Router seems to several MAC addresses

    My WRT54G wireless router's MAC address (as written on the label underneath) ends with F5. LELA shows the LAN MAC address as ending in F5. It shows the WAN MAC addrerss as ending in F6.
