Ghost IP, can't locate it

[Fribse]

Hi All

We have a ghost IP. I can ping it, but I can't find it.

I've done the usual stuff.

show mac-address

not shown

ping ip

show arp

The IP is shown, but the port is empty??

I've looked through running-config without finding it.

What to do?

This is a stacked switch, four switches in a 2x2 failover.

Hello Fribse ,

Looks strange and intersting , can you let me know the model of switch and it is possible add the current config  ?

Also share the ghost IP and trace to the ghost ip from your network

These may sound like odd ideas, but in my environment (access points, credit card machines, voip phones) etc  I try the following.

1. Try to open the ip in a browser

2. Try to ssh to the ip with putty or equiv.

3. Try to rdp/vnc to ip

4. Try mac/ip binding in your firewall and block it...see who squaks

5. Perhaps it's tied to a vlan

good luck
