when dhcp snooping entries removed ?

[Burak_Kale]

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,

Please explain in greater detail what you are wanting to accomplish.

We are using the dhcp snooping feature to ensure about DHCP security

Thanks

Burak,

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

Hi Joshua;

Thanks for the quick reply.

Is it same when we are using different dhcp server ?

Because i am just asking about dhcp snooping.

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
