Block non-DHCP allocated client on the switch

HI !

Does Cisco switch can block clients that did not get an IP from the DHCP server via the switch ? For example map MACs which got an ip through switch DHCP relay client and put it in some table, then if someone defines an IP manually on the client - just block this client on the port level and does not allow him to connect to the network.

thanx !

Yes! It is possible to do exactly that.

Please read the following paragraph:

http://www.cisco.com/en/US/customer/products/hw/switches/ps5023/products_configuration_example09186a00807c4101.shtml#dynamicarp

You will need to enable DHCP snooping.

Hope this helps.
