BIGIP cannot remove Virtual IP out of F5.

Hi All I have the F5 BigIP 10.0.1 very old device and I tried to migrate my virtual IP to another equipment. I delete virtual IP address in the F5 and would like to use the same IP address to enter in other device but look like F5 still holding it some how even request timeout when I ping that IP. I had deselect the ARP update in Virtual IP Address list but got no luck to reuse the same IP for another device. Anyone have run into the same problem like this? Please help. Thanks in advanced.

    Hi

     

    You could check arp table on bigip and gateway switch to confirm if the ip is binded to a mac.

     

    You could use delete command on bigip to delete arp entry.

     

    Let us know your input after this check.

      Thanks for your respond. I look under BigIP utility NETWORK - ARP but I only saw the self IP bind to the mac address in dynamic list. Is there the command line I can use to see the list of all the IP's in ARP table? Thanks for your help
