Hi ;

I know that we can clear dhcp-bindings for a port manually.

Are there any way to clear dhcp-bindings when an interface is down ?

Is there any way to create a timer for that or am i have to wait for the dhcp lease time?

Regards,

Burak.

Burak,

What can you specify the role the Extreme device plays in the DHCP process?

Burak Kale,

If you are using an Extreme EXOS device you can use the following command to set the lease timer for DHCP:

configure vlan dhcp-lease-timer

If you want to clear the existing DHCP allocations use the following command:

clear vlan dhcp-address-allocation
