6509E with Sup720 - Show mac address

I have seen very strange behavior. The following two commands show different outputs...
core2#sho mac address-table dynamic | in cc04
     7  0009.0fbb.cc04   dynamic  Yes        150   Po10
core2#sho mac address-table address 0009.0fbb.cc04
Legend: * - primary entry
        age - seconds since last seen
        n/a - not available
  vlan   mac address     type    learn     age              ports
------+----------------+--------+-----+----------+--------------------------
No entries present.
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!

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.

  • 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?

    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.

  • Show mac-address-table not working on ASA5512

    Hi,

  • 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?

    0100.0ccc.cccc is used for CDP/VTP/DTP/PAgP/UDLD
    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.

  • Printer showing MAC address in sidebar

    I have just setup a Canon MX850 printer on my home network and the MAC address of it is showing in the sidebar. The only way to remove it is to change the sidebar preferences which I don't want to do as I want to see other servers on the network. How do I change the printer settings to show the MX850 instead of the printers MAC address?

    I have never seen this with any of my Canon printers. I have an iP5200R that is connected wirelessly to my network and an iP6000D that is connected to the USB port of an Airport Extreme. When I configured the iP5200R to join my wireless network, it was displayed in the Canon utility with its MAC address. Also, when I added its printer queue using More Printers > Canon IJ Network, the printer was also shown in the list with its MAC address. However, as I write this reply this printer does not display in any part of the Finder.
    Is the printer displayed under the Shared section in the sidebar?
    Also, how is the printer connected to your network? Is it being shared by another computer or is it connected via Ethernet or wireless?

  • Cat 2960 shows mac address port as "Drop"

    Hi all
    I am configuring a Cat 2960 port for connecting a VOIP phone, authenticated by MAB.  On connecting the phone, I get the port authenticated and assigned to the correct VLAN, with LLDP-MED advertising the correct voice vlan.  However, I then see no traffic from the phone on the switch.  I can see the MAC address of the phone is learned in the right VLANs, but the mac address is showing as "Drop", which normally means the address is statically configured to be blocked.  There is no static mac address table blocking configured on the switch.   Can anyone suggest why this is happening?

  • Use TCP, UDP, or other to communicate with UUT using MAC address instead of IP address

    I want to verify that the Ethernet port on my UUT works. 
    My plan was to ping the UUT and verify that I got a response.  However, the UUTs will come to test with an IP that I cannot use on the network.  [Please don't ask me to explain why -- the IT group has their rules, and rules are rules after all . . . ] 
    I can query the UUT (via the serial port) for it's MAC address.  But I cannot find any LabView VIs, or DOS executables which use the MAC address as a parameter to invoke a response from the device.
    Does anybody have an idea of how I can verify the UUT Ethernet port without having to divorce myself from the company network and set up my own private network?  [Oh and by the way, before somebody suggests it, the IT group won't let me put a 2nd network card in my PC -- rules are rules after all . . . .]

    I wouldn't worry too much about the address shown in the Remote Management tab.  The ARDAgent process, which is what is listening on his computer for connections from Remote Desktop, binds to all active network interfaces and ultimately that's all that matters. Of out curiosity though, to what IP address does the "unknown-b8-8d-##-##-##-##.home" dns name resolve?  Is it the WAN address?  I can't imagine it resolves to a private address like a 192.168.
    In any event, let's focus back on the network structure. Does the BT router have both a hard wired LAN ethernet port as well as a WiFi radio for LAN connections?  My guess is yes. I am also assuming that he does *not* have another router attached to the BT LAN ethernet port like an Airport basestation that is serving the WiFi connections.  Typically, the LAN ethernet port is given, via DHCP, a real Internet accessible address but the addresses served via DHCP for wireless clients are private network addresses only.  It's seems unlikely to me that the router is automatically forwarding incoming connections to a private network address on the WiFi network.  But if he plugs his Mac in to the ethenert LAN port on the BT router then you should be able to connect directly to the address given to it via DHCP because it *should* be a real Internet accessible address.

  • Sh arp does not show mac address of IP --- ASA

    Hi Everyone,
    I can ping the IP from the ASA but when i do sh arp it does not show me mac address od that IP.
    Need to know the reason behind this.
    Regards
    MAhesh

    So your ASA should have a route on the inside interface to internal networks. The address of that next hop in the routing table is the one you should have in your arp table allowing you to reach non-directly-connected (subnet-wise) hosts within the scope of that route statement.
    Think through the logic - ASA pings a host. It needs to determine proper egress interface. It checks and asks "Is it reachable via a directly connected interface (most preferred route)?" Answer no. "Do I have a route statement telling me how to get to it?" Answer yes (otherwise use default). OK - so ASA sends packet out egress interface defined in that route statement to the next hop as defined in route statement and waits for reply.

  • Reports for Apple devices with SCCM client - Mac Addresses and IP information.

    Greetings.
    I've been having an interesting problem.
    I am currently running SCCM 2012R2 with PKI and have clients installed on windows, linux (ubuntu mostly) and apple computers successfully.
    I have created custom report proving me with hardware information for windows and linux machines (Serial numbers, manufacturer, Mac Addresses and IP addresses) successfully.
    So far I wasn't able to create any report or even find what table information about Apple computers MAC and IP addresses is stored.
    If i go to Apple computer in SCCM using resource explorer under hardware I can see network devices, so that information is definitely gathered by SCCM in some way.
    Can anyone help me out with this and maybe I am doing this in a wrong way?

    Nice. Only trouble there seems to be multiple entry for same mac address there for same resource id.
    So when I try to get them as substring i get multiple copies of same mac address.
    But looks like this will work as solution to this problem.
    So far I was doing it this way (And i am sure there is clearer way to do it.)
    SUBSTRING((SELECT ',' + CAST(t2.MACAddress0 AS VARCHAR(40))
                FROM (SELECT DISTINCT ResourceID, MACAddress0 FROM  v_GS_NETWORK_ADAPTER) t2

  • Configuring new iPad with a network with locked down MAC address

    I've just got the new iPad and feel there is a 'flaw' with the new configuration. 
    With iOS 5 it reduced the need to 'tether' to a PC, however unlike a Mac, on the packaging box it does not list the MAC address for the iPad.
    Now if your network is locked down with MAC address entry, there is no way of getting that information as it is not shown when using the configurator or as I mentioned, on the box.  The only way to join to your wireless is to remove the access restriction on the network, which runs a security risk.  Or, go 'old skool' and use iTunes to configure, which defeats the point of not being linked to a PC.
    Apple, please either add the MAC address to the packaging label, next to the serial. Or, have the information viewable during the wireless configuration. It's not too much to ask is it ?
    Or does anyone else know of a work around or way of getting this information ?

    When using the 'untethered' configuration, you could choose not to join a network. This would let you setup the iPad with everything except a network connection. Then, I may be wrong here, once up and running go to SETTINGS -> GENERAL -> ABOUT and look down the list. Near the bottom there's an entry for WiFi Address. Looks like a MAC address to me. Put that address in your router and you should be good to go.
    OK, you can't set up the network during the initial 'just out of the box' stage but it's  only one extra step. I think the untethered setup is fine as far as it goes, but maybe there should at least be some documentation to explain how to get the MAC address if it's needed?

  • NAM shows MAC address instead of IP address in host

    Hi,
    Product: Cisco Prime NAM Appliance 2304
    Version: 5.1(3)
    Problem: We only can see MAC address on Hosts table in NAM, not IP address.
    Does anyone know what happen and how to fix it?
    Thanks!!!

    I wouldn't worry too much about the address shown in the Remote Management tab.  The ARDAgent process, which is what is listening on his computer for connections from Remote Desktop, binds to all active network interfaces and ultimately that's all that matters. Of out curiosity though, to what IP address does the "unknown-b8-8d-##-##-##-##.home" dns name resolve?  Is it the WAN address?  I can't imagine it resolves to a private address like a 192.168.
    In any event, let's focus back on the network structure. Does the BT router have both a hard wired LAN ethernet port as well as a WiFi radio for LAN connections?  My guess is yes. I am also assuming that he does *not* have another router attached to the BT LAN ethernet port like an Airport basestation that is serving the WiFi connections.  Typically, the LAN ethernet port is given, via DHCP, a real Internet accessible address but the addresses served via DHCP for wireless clients are private network addresses only.  It's seems unlikely to me that the router is automatically forwarding incoming connections to a private network address on the WiFi network.  But if he plugs his Mac in to the ethenert LAN port on the BT router then you should be able to connect directly to the address given to it via DHCP because it *should* be a real Internet accessible address.

    I had the same problem. SUN support recommends latest kernel patches. That solved my problem.

  • 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?
