Can you tell the IP address of a device attached to a 6500 Catalyst Switch

I have devices attached to a Catalyst switch, and I wanted to find out which device is attached where by checking the IP address of a specific device attached to a port. The ARP tables don't show any devices. Anyone know a quick/dirty way to do this?

The arp table on your switch does not show this as the switch does not talk to devices directly and thus does not need this information. Do this:
- From the switch ping devices you want to find where attached to.
- type "sh arp" on the switch. This time it will contain the information you need.
Similar to this:
switch6500> (enable) sh arp
ARP Aging time = 1200 sec
+ - Permanent Arp Entries
* - Static Arp Entries
10.0.0.1 at xx-xx-xx-xx-xx-xx port 1/1 on vlan 15
10.0.0.30 at yy-yy-yy-yy-yy-yy port 1/1 on vlan 15
switch6500> (enable) ping 10.0.0.20
----10.0.0.20 PING Statistics----
5 packets transmitted, 5 packets received, 0% packet loss
round-trip (ms) min/avg/max = 1/1/1
switch6500> (enable) sh arp
ARP Aging time = 1200 sec
+ - Permanent Arp Entries
* - Static Arp Entries
10.0.0.1 at xx-xx-xx-xx-xx-xx port 1/1 on vlan 15
10.0.0.30 at yy-yy-yy-yy-yy-yy port 1/1 on vlan 15
10.0.0.20 at zz-zz-zz-zz-zz-zz port 3/22 on vlan 15
switch6500> (enable)

  • Can you tell if someone has tracked your device?

    Can you tell if someone has tracked your device?

    Nobody can track your device without your AppleID and password. If someone else knows your password, they could have used Find my iPhone to track your device. Change your password if you suspect this to be the case.

  • Can you tell the output type within template?

    Hi all,
    we're using Oracle apps 11.5.10 and we have the usual leading zero problem when exporting to Excel.
    From what I've read, Excel uses the 'TypeGuessRows' registry setting to read through a specify number of rows to decide whether a column is numeric and then drops the leading zeros. I've also seen the proposed solution of putting a quote mark to trick Excel. We have a requirement to display the right numbers including leading zeroes in both PDF and Excel. So now I'm down to 2 choices.
    1) create a separate template for PDF without the quote or my question
    - Within a template, can you tell what the runtime output type is? Does the XML Publisher engine provide a way to obtain this value within a template?

    Hi Mike,
    I used
    <fo:bidi-override direction="ltr" unicode-bidi="bidi-override"><?D_INVOICE_NUM?></fo:bidi-override>
    and it still didn't work. The invoice number is alphanumeric an sometimes just contains numbers with leading zeroes which is what I'm testing with.

  • In ical, how can you tell the difference between a meeting invite and email?

    When you send a meeting invite in ical, does the recipient receive a different icon in their inbox to differentiate from an email?

    For service stock you can't tell the difference between a new iPad and a refurbished one. Both will come in a plain brown box with the same pattern in model numbers. If you mean between a refurbished one and one new at retail, then other than the obvious difference in packaging, I've read that the model number on refurbished units starts with the letter "F", though I've not confirmed that.

  • Can you change the email address to where your Bro...

    Hello.
    My BT Broadband account BT Internet emaill address is a different email address to my everyday BT Internet email address that I use to send from and receive emails in.
    I don't send emails at all from my BT Broadband account email address.
    Therefore when my BT Broadband Usage goes over 6GB and then 8GB, I am not aware of it unless I log into my BT.com account and check or log into my BT Broadband account btinternet.com email address as the advisory emails go into that address which I don't use for emailing from.
    Is there any way I can have these advisory emails sent to my everyday BT Internet email address instead? Or even continue to be sent there and my main email address? Either by being able to do anything online or by contacting BT by phone or email and have them do it?
    I did actually contact BT once before by emailing them and someone in India phoned me back to say they will do that for me but they've not done anything at all for me and the advisory emails still continue to go into my BT Broadband email address instead.
    Could anyone tell me if switching the email address or adding an email address as to where these BT Broadband Usage emails are sent to is possible?
    Hope it is and that you can tell me how this can be done with any helpful link or contact address/number without speaking to anyone in India.
    Thanks.

    Hi, I have the same problem, except that the advisory emails are being sent to a completely new email address which I never set up and which I can't access or login to.  I didn't know about this until a bill arrived with a £5 charge for excess broadband usage, but I didn't know how to check it until now.  I have now received an email (to my correct address) saying "Keep an eye on your usage" which has a link to an online monitor and to my horror I see that my usage has been well over the cap for some months.  Yet I never received the advisory emails because I had no idea they were being sent to the unknown address.  How can BT invent an email address and then use it to warn me?  More to the point, how do I change that email address?  I can't login to it because I don't know the password!
    Any advice would be gratefully received.
    Tony.

  • How can you edit the Email Address field in Mail without deleting the account?

    I have a few accounts and the email address domain of my work account has changed but it seems to be one of the fields you cannot change.
    On my iPhone it was simple ... you can just edit the field and it works.
    My Email comes in fine but mail auto selects accounts based on the domain of who you are emailing and now that it has changed its not doing that anymore.

    If you're running iOS 6, to change your iCloud ID go to Settings>iCloud, tap Delete Account, then sign back in with the new ID.  This deletes the account and your iCloud data from your device, but not from iCloud.  Provided you are signing back into the same account, your iCloud data will reappear on your device when you sign back in.
    To avoid losing photo stream photos, save them to your camera roll (if not already there) before deleting the account.  To do this, open your my photo stream album, tap Edit, tap the photos, tap Share, then tap Save to Camera Roll.

  • Can you tell the date of a picture someone texted you

    Someone texted me a picture last night that they told me they had just taken. I know they're lying, but I don't know how to prove it. Is it possible to get date/time information from a photo someone sent you? It was sent from one Iphone to another.

    GeekBoy.from.Illinois wrote:
    This is probably more accurate than looking at the EXIF data embedded in the photo, since that would show you when the photo was taken, not sent to you.
    Except, of course, the OP specifically wants to know when the phone was taken. 
    And, of course, this assumes that the EXIF data was not edited.

  • Can you change the udev ATTRS for a device?

    In particular with programs that access optical media lately, it seems to be popular to refer to them in various softwares by their vendor/model/rev (ie: 'TSSTcorp CDDVDW SH-S223F SB02').
    This gets confusing and messy when you have multiple of the same device.
    Is it possible to write an udev rule that would change it to something else, like maybe 'TSSTcorp CDDVDW SH-S223F SB02 /dev/sr0', or something, so I can actually tell my drives apart when they're referenced that way?

  • Can you rename the Personal Address Book and the Collected Address Book?

    You can rename them but it is not recommended. What purpose is served by renaming the default books? You can create new books and name them anything you like.

  • How can I identify the IP address of a device on my LAN?

    If I attach a device to my LAN but have no idea of its IP address (ie it may not even be communicating), is it possible to identify its static address?  Or will it only respond (to something like nmap) if the route of the transmitting device device is correct?
    For instance, my PC is 192.168.0.4 and its default route is 192.168.0.1.  If I attach another router that has an address of 192.168.1.254, how can I determine that its physically connected?   Using nmap -PR 192.168.0.0/16 for host discovery doesn't reveal its there unless I change the default route to (something like) 192.168.1.1

    I realise that, but they are sat at each end of a 1m ethernet cable and I want to know if its possible to recognise there is a device on the physical network even though its on a different subnet.
