How to find which port on the switch that it connected with Mac address?

Hi,
I am trying to find which port of the switches it connected to thru mac-address?
I am able to get the mac-address from the ip address when i do
"show ip dhcp binding snooping" at the core switch.
But when I move on to the Edge switch to check which PC with this Mac address connected to the port,i returned with no result.(onli trunk port result)
I use sh ip arp | inc 000d.60cb.445d
but didn't give me which port it connected to.
How to solve this problem?
thanks!

Hi KL,
If you are already on the edge switch you can run a command "sh mac-address-table address " and it will give you the port number.
Incase you get a port which is a trunk port that means the end device does not exist on this switch and exist on some downstream switch. So you can just find out the ip address of the downstream switch with "sh cdp neigh detail" command and connect to that downstream switch and then again issue the command "sh mac-address-table address " and check the port number and follow the above steps till the time you get the switch on whcih end host is connected.
HTH, if yes please rate the post.

  • How to find which Port has the highest traffic (both in/out) in switch

    Hello,
    I have a 3550 switch with 48 port having 12.1 code.
    Need to know which port is causing the highest traffic , i mean to track which user is downloading/uploading the most.
    I was able to track this in CATOS with the command sh top and that will tell the port, but in IOS based switches i was not able to find
    Can some one help.

    You can try with the following command:
    show interfaces summary
    Output shows the traffic for all ports instead of the top one only, but you can find the top from this output. Or you can install an MRTG or Cacti for monitor the used bandwith.
    bye

    Please rate me if I helped.

    well if you know the user through which your application is connected to instance, you can easily find out by querying gv$session view.
    select inst_id,sid,serial#,program,username from gv$session where username is not null;

  • How to find out what server the outlook client is connected to/change it automatically

    Hi,
    I am performing a server migration from Exchange 2010 to Exchange 2010 (the previous installation was installed by an outsourced provider and is rubbish so I'm configuring it properly). On the of things the existing server lacks is a CAS array configured,
    so I have built the new Exchange 2010 server, configured a new DB and CASArray. I have created a brand new mailbox for a new user and the user's outlook shows it is connected to casarray.domain.local, I have migrated my own mailbox but internally my outlook
    shows it is connected to oldserver.domain.local (under the account settings when you go to change the settings for the account), this is on a domain joined internal desktop. But at home on my personal laptop non-domain joined, it has appeared to reflect the
    new casarray.domain.local. The outlook client is 2007 in both situations.
    When I run the following command, it shows my mailbox is indeed connected to the new exchange server, but this is not true in outlook
    Get-LogonStatistics -Server "new-exch2010" | where {$_.clientname -eq "new-exch2010"}| ft username,servername,clientname
    If I run the above command against the old server my name shows on that list as well. When I look at the connection status of my outlook it shows that it is connected to casarray for directory, but the old server for mail.
    A couple of other things:
    Mailflow is now going to the new exchange server from the gateway over port 25, the autodiscover record in the internal DNS is now also pointing to the new exchange server, outlook clients and users computers have been completely restarted but still don’t
    seem to pick up the new settings, both the old server and new server functions as a multi-role exchange having the Hub, CAS and MBX roles.
     Now that you have all that background info my question is two parts:
    What is the correct powershell command I can run on the exchange server to ensure that all my outlook clients are connected to the new exchange server for all connection types (or identify those which are connected against the old server)?
    How do I get the outlook clients to automatically pick up the casarray servername once their mailboxes have been migrated?
    I am considering removing the CAS from the old server which may force outlook to find it’s new server but am unsure whether this will work or not, and I think I should migrate all the mailboxes into the new DB before I do this.
    Other than that, I am out of ideas.
    Appreciate, any help. Thanks
    Steve

    I had already run the command Get-MailboxDatabase | FL Identity,RpcClientAccessServer
    and it only identified the old database as being tied to the server name, the new database has the correct casarray and all mailboxes are in this new database. should I also set the old database to point to my casarray as the second command indicates? can't
    do any harm right?
    also, I have outlook 2007 and 2013 at home and both of them had automatically reconfigured
    themselves to point to casarray, my problem is with the internal clients.
    today I have also noticed in DNS there is a Zone which points to autodiscover.domain.co.uk
    and in there it points to my old server.
    a few things to note about the above:
    1. the zone is pointing to the .co.uk domain not the .local - is this correct?
    2. should that zone even be in our internal DNS, i hadn't noticed on previous implementation
    of Exchange I have done
    3. if i change the record within that zone to point to my new server, will this likely show
    up the popup message shown in this link http://www.rackspace.com/apps/support/portal/1218 I havent yet got a certificate for the new exchange server (few more days) and i dont want users seeing any kind of untrusted unsecure connection box or it
    will only lead to panic and flooding the helpdesk
    many thanks

  • How to route two vlans on two switches that are connected only on one router?

    Suppose that any of the trunk links fails or if you want, suppose that there is no link between SW1 (G0/1) and SW2 (G0/1). How can you make computers in Vlan 10 to see computers in Vlan 20 and viceversa?. I tried creating a bridge group on the router for G0/0.10-G1/0.10 and another for G0/0.20-G1/0.20. Then define interface BVI10 and BVI20. Interfaces came up but you can not configure dot1q on them and switches can not see them. Anyways with one interface on the bridge group going down the BVI interface goes down as well so that's not an option. Router should be 10.10.10.1 and 20.20.20.1 and each computer have that as gateway respectively.

    Jody thanks very much!
    Indeed the encapsulation was done in the sub-interfaces, as posted in the OP you can not [encap dot1q X] on the BVI interface. Even though, the switches didn't established the trunk with the BVI. Anyways using bridge groups is not an acceptable solution because with the failure of any interface of the trunk links in the router, the BVI interface goes down as well.
    You said "if I want to handle it at layer 2" How will you do it at layer 3? I though something like HSRP or VRRP but that doesn't apply since it is only one router. Remember, the router must be able to route between vlan10 and vlan20 for computers on both switches in case of one of the trunk link failure.
    This is for learning purposes so I started with Packet Tracer but PT doesn't support bridge groups. Then I tried GNS3. I will try with the router in GNS3 with a switch module but I'm not clear. that will be like having a 3rd switch, right?  What I mean is that I will not be using routed interfaces between the router and the switches, right?

  • How to find which attribute in the view object is dirty

    Hi all,
    I am using Jdev 11.1.2.2
    I am using this code to find if a data control is dirty
    iterator.getDataControl().isTransactionDirty();
    But is there a way to find out which attribute is dirty ?
    Thanks in advance

    Never tried but give this a try.
    1. Invoke ViewAttributeDefImpl[] VO.getViewAttributeDefImpls().
    2. For each ViewAttributeDefImpl, invoke isDirty().
    You may need to expose a VO method to make this accessible in view layer, if this works.

  • How to find which process locked the directory

    I have a folder with some TFS-projects. So now i want to rename or move my directory, it says that "the action can't be completed because
    thefolder or a file in

    Hi,
    You can check with:
    1. MMC - Shared Folders (if it is a shared folder). Here you could check Open Files to see if files are locked by other users with opening a file in your folder. You can kill the session to unlock a file.
    2. Download this tool:
    http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx
    Handle.exe could help check locking session on your computer. See if your file in that folder is listed and use -c to close the handle.

  • How to find which authentication used to site collection and site using powershell

    Hi,
    How to find  how-many web app, sitecollection, site used Windows authentication,claim authentication and classic, secure store authention , adfs authentication using powershell code in sharepoint 2013.
    If sites are used adfs authentication how to find which email id used for that.
    Thanks,

    Authentication is only defined at the Web Application level, and the only valid auth methods are Classic (Windows (Basic/NTLM/Kerberos)), Claims (Windows (Basic/NTLM/Kerberos)), FBA Claims, , SAML Claims (ADFS), and Anonymous.
    You can find out what authentication scheme(s) are enabled via:
    $wa = Get-SPWebApplication http://webApp1$wa.IisSettings["Default"] #replace with the zone name you're interested in
    The output will look similar to this:
    PS C:\Users\trevor> $wa.IisSettings["Default"]
    AuthenticationMode : Forms
    MembershipProvider : i
    RoleManager : c
    AllowAnonymous : False
    EnableClientIntegration : True
    ServerBindings : {Microsoft.SharePoint.Admini
    stration.SPServerBinding}
    SecureBindings : {}
    UseWindowsIntegratedAuthentication : True
    UseBasicAuthentication : False
    DisableKerberos : True
    ServerComment : SharePoint
    Path : C:\inetpub\wwwroot\wss\Virtu
    alDirectories\spwebapp180
    PreferredInstanceId : 42768054
    UseClaimsAuthentication : True
    ClaimsAuthenticationRedirectionUrl :
    UseFormsClaimsAuthenticationProvider : False
    FormsClaimsAuthenticationProvider :
    UseTrustedClaimsAuthenticationProvider : False
    UseWindowsClaimsAuthenticationProvider : True
    OnlyUseWindowsClaimsAuthenticationProvider : True
    WindowsClaimsAuthenticationProvider : Microsoft.SharePoint.Adminis
    tration.SPWindowsAuthenticat
    ionProvider
    ClaimsAuthenticationProviders : {Windows Authentication}
    ClaimsProviders : {}
    ClientObjectModelRequiresUseRemoteAPIsPermission : True
    UpgradedPersistedProperties : {}
    So on this Web Application in the Default Zone you can tell I have Windows Claims enabled, not using Kerberos (so using NTLM), and Trusted (SAML/ADFS) is not enabled, neither is Forms or Anonymous.

    Well blow me down & keelhaul me! I've solved my own problem. The issue appears to be that Apple won't sync Smart Groups from Address Book to the iPhone. I created a test group with a few dud contacts in Address Book; iTunes sync'ed then OK & as soon as I went into Contacts on iPhone, there suddenly was the Groups button appearing with 2 Groups - my Test Group + all Other contacts. Nice one apple - another undocumented feature! Looks like I have to do away with the Smart Groups feature & convert them all to normal Groups in Address book - bugga!

  • How to find which function module write the relevant idoctype?

    Dear All,
    how to find which function module write the relevant idoctype?

    Hi,
    Generally the function modules of the idoc types are having a naming convention as IDOC_INPUT for inbound processing and IDOC_OUTPUT for outbound processing followed by the idoc type name
    for example : For IDOC type ORDERS
    the inbound function module will be IDOC_INPUT_ORDERS and for outbound IDOC_OUTPUT_ORDERSP
    In this way you can find the function module for a particular IDOC
    P.S: Hope this is what you have asked for
