Show Mac Address Table in ASR9k running XR

I'm trying to find a Mac Address in the ASR9k table.  We have a server with multiple mac addresses and we need to know what MAC is being learned by what interface.
Thank you,

Use the command
show l2vpn forwarding bridge-domain <group_number>:<domain_name> mac-address location 0/x/CPU0
or
show l2vpn forwarding bridge-domain mac-address location 0/x/CPU0

  • Show mac-address-table not working on ASA5512

    Hi,
    I'm unable to excute "show mac-address-table" on an ASA5512, running 9.1(1). The output is: 
    asa-test# show mac-address-table
                     ^
    ERROR: % Invalid input detected at '^' marker.
    Has the command changed for this model / version? It works fine on ASA5505's running 8.4(5).
    Thanks for your time,
    John

    hi john,
    the show mac-address-table command should be valid.
    check if you've got MAC learning enabled on the ASA interface using show mac-learn command.
    edit: could you post show firewall? the above command works on transparent firewall only.

  • CNA 5.5 and show mac address-table

    When trying to Monitor/Search for MAC address in C2960 network I got an error reply that a CLI command is not supported. Analyzing network traffic shows that CNA 5.5 is issueing 'show mac-address-table' command but the latest Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 12.2(55)SE does not support 'show mac-address-table' anymore but does support 'show mac address-table' command. How can I change the command for showing mac address tables in CNA 5.5?

  • Show mac-address-table

    Given the command show mac-address-table from the privilege exec mode in a cat 2950, the output shows some (i think 4) mac-address tha are system. Do u have any idea what are these mac?

    Hi Dimitris,
    Thanks for writing in. I tried the command on my switch and got the following: Do you see a similar output and is this what you are referring to?
    2950#sh mac-address-table

    0100.0ccc.cccd is used for PVST+
    0100.0cdd.dddd seems to be related to multicast, however need to confirm on this.
    0009.7c70.f9c0 is the mac address for my management vlan interface.
    2950#sh int vlan 1
    Vlan1 is administratively down, line protocol is down Hardware is CPU Interface, address is 0009.7c70.f9c0 (bia 0009.7c70.f9c0)
    Hope this helps.

  • CSCui55504 - show Mac address table from RP gives an error msg and40;but from SP works )

    Hello Cisco,
    Is there any updates or ETA regarding this bug, as our production 6500 core switch is experiencing this issue and viewing mac-table is a critical activity we perform everyday to troubleshoot client connections.

    I'm having this same issue. I also have this line in my log, which is curious:
    12/14/14 7:13:07.822 PM netbiosd[16766]: Attempt to use XPC with a MachService that has HideUntilCheckIn set. This will result in unpredictable behavior: com.apple.smbd
    Is this related to the problem? What does it mean?

  • 6509E with Sup720 - Show mac address

    I have seen very strange behavior. The following two commands show different outputs...

         7  0009.0fbb.cc04   dynamic  Yes        150   Po10

    Po10 is etherchannel to core1. The MAC address is on the core2 and should never be learned on core1. Core1 doesn't learn this MAC address at all.
    The commands are run at the same time. I repeated many times and it is the same... Any idea why?
    Thanks!
    Difan

    Hi Jon,
    Correct, I am not using VSS. However it is not standard set up. The vlan 7 is extended to many other switches. The root is actually not core1 or core2. It also passes some provider to different location as well. However like you said, all the correct ports are blocked. Please trust me on this.. If there is a loop, we will have much more serious problem... At least our CPU will hike and link will congested, right?
    I know your concern that the same packet could be somehow loopped back through core1, which makes core2 to learn the MAC on the port-channel interface to core1. However when this happens, core1 doesn't learn the MAC anywhere and on core2 some command show the MAC but not the other command...
    Also something interesting, even that MAC in the command will eventually disappear. Please note the aging time. The aging time configured on the vlan is 480 seconds. At last the MAC address is pointing to another interface like G1/1. That interface doesn't even have vlan 7 allowed on the trunk link.

  • Mac address table corruption?

    We are running Cisco 4500 chassis at the access layer, and have been for a few years without issue. Recently we started to experience issues where a mac address will just randomly "jump" to another port. User will call us and say their computer is not working. We will locate the mac, and its showing on the wrong port. We shut that port, do a no shut, and the mac jumps back to the correct port. In the example below, the mac address jumps to port 3/2, but is physically connected to 2/12.

    Switch is running cat4500e-entservicesk9-mz.151-2.SG2.bin , but also happened on cat4500e-entservicesk9-mz.151-2.SG4.bin and cat4500e-entservicesk9-mz.150-2.SG4.bin. Other switches have also had this issue occur.

    Looks to be me like a bug.
    could you please provide me some more details on this:
    1- How often this issue is occurring?
    2- Is this occurring to specific ports or specific laptops which are connecting to this ports or is it irrespective of devices?
    3- Is there any possibilities that you try rebooting one of the switch if the issue is very often? (I know this is not a feasible solution , I know it is some issue iwth the firmware but in case to avoid high impact you can reboot the switch and update me?
    4- Provide me with the logs from the switch?
    5- I will do the bug scrub and let you know.

  • Can't clear mac address table from interface

    hello all.
    I'm facing a problem, and i've also tried to workaround but not sucessfully.
    I've got a polycom phone on the swich. When I connect a laptop on that port, the mac address is learned by the switch and keep the mac address even if I disconnect the ethernet cable from that port and if I try to connect the same laptop on other port on the same switch I've got errdisable error in the last connected port. Although I was figuring out what's wrong and seems that the mac address is kept for some reason in the first port.
    sw02#show mac address-table interface f0/19
              Mac Address Table
    Vlan    Mac Address       Type        Ports

     80    0004.f21e.afa7    STATIC      Fa0/19 
    this is a 2960, Version 12.2(44r)SE4
    with a Polycom SoundPoint IP 330 connected on vlan 80
    I was searching to clear the mac address table on that interface but the IOS version didn't give me the static option
    sw02#clear mac address-table ?
      dynamic       dynamic entry type
      move          move keyword
      notification  Clear MAC notification Global Counters
    As there's no dynamic entries on that interface the mac addresses remain on the f0/19 interface.
    I've tried with other switches and with other laptops and is the same errdisable status.
    sw02#show run int f0/19
    interface FastEthernet0/19
     description VoIP

     switchport port-security
     no snmp trap link-status
     ip dhcp snooping limit rate 100
    end
    any thought?

    the mac addresses are not manually configured.
    yes, that's my point. when I disconnect the ethernet cable the mac addresses are not flushed from the mac table.
    Although I don't understand why the mac addresses are kept in the interface, if I force the interface aging time to 1 min, the problem don't occur anymore.
    I was reviewing the switch config and I've got ports with aging time 0 (that learn and flush the mac addresses dynamically) and I've got ports with aging time 1 (that learn and flush the mac addresses at the end of 60 seconds)
    The problem is solved although I need to investigate this issue in other switch models and with other voip phones.
    Tks Jon and Julio

    Rick

    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.

  • Why "mac-address-table static 0000.0c07.ac01 interface FastEthernet1/0 vlan 3" in the router ?

    Hi All
    I did not type the following command. Why does it appear when I show run ? Which command can cause the issue? Thank you
    mac-address-table static 0000.0c07.ac01 interface FastEthernet1/0 vlan 3

    Hello,
    It looks as if you have HSRP configured.  Mac address 0000.0c07.ac01 is the HSRP virtual mac address.  01 at the end of the mac represents the HSRP group number.
    Hope this helps,

  • Mac Address Table

    Hello, 
    In one of our core switches, the output of the mac-address-table shows some mac addresses which come up as MPLS Multicast address when I looked them up under MAC Manufacturer(See below). Also, in the mac-address-table under the port column,  those mac addresses display several ports associated with them and the word Router(see attachement). My question is, why are these MAC addresses come up as MPLS Multicast and why under the ports is it has the word Router? 
    Thanks in advance...

    Hi,
    Yes multiple MAC addresses are supported on each port. The switch learns the MAC by noting the source address of the packet received on each port and on that basis it builds what we call MAC address table. There is an aging mechanism in place which removes the inactive MAC addresses and allows new ones to be learned as devices are connected and disconnected.
    The default aging time is 300 seconds, however if need arises you can change the same by giving the command - 'mac address-table aging time number vlan vlan-id'.
    Have a look at the following link-->
