  • 1.  Clear DHCP lease

    Posted 26 days ago

    Hello,

      does anyone know if there is a way to manually clear DHCP leases from an appliance acting as DHCP server? Such an option does not seem to be present in Orchestrator -and neither in CLI.

    Thanks,

    //Anibal

    for Aruba branch gateways like 9004 the command is "clear ip dhcp binding"

    (Aruba9004-LTE) #clear ip dhcp binding ?
    ip-address              Clear DHCP Server binding for a specified IP address
    <cr>

    Hi,

    Thanks for your answer. That option does not seem to be present, though:

     

     # clear ip dhc                                                                                                                                                            

    % Unrecognized command "ip".                                                                                                                                                        

    Type "clear ?" for help.                                                                                                                                                            

    SD01 # clear ip dhcp                                                                                                                                                           

    % Unrecognized command "ip".                                                                                                                                                        

    Type "clear ?" for help.                                                                                                                                                            

    SD01 # clear dhc                                                                                                                                                               

    % Unrecognized command "dhc".   

     

    SD01 # clear ?                                                                                                                                                                 

    arp-cache                       Clear dynamic entries from the ARP cache                                                                                                            

    cluster                         Clear cluster stats counters                                                                                                                        

    ddos                            Clear DDOS statistics                                                                                                                               

    denylist                        Display dynamic denylist addresses                                                                                                                  

    flow-redirection                Clear flow-redirection counters

    CARNRSD01 # clear                                             

     

    We are probably looking at a different platform:

    This is an EdgeConnect appliance. Commands you tried [and were pointed to] are for ArubaOS gateways, which is a different device.

    The CLI guide for EdgeConnect appliances is here. But I don't think you can clear the DHCP server. You may reach out to support if it is possible at all.

    On the EdgeConnect CLI you can renew the DHCP leases on an interface. You need to be in configuration mode then type the below but change the interface based on how yours is configured. Below I have used lan1
