I'm confused by your question, Kings, The same guide says that to configure "manual bindings" one must enter "client-identifier" command. What made you think that the "hardware-address" option didn't work? Were you able to simulate BOOTP instead of DHCP request with option 61 ?

Instead, if I specify the client identifies, it works. ip dhcp pool cat host 10.20.30.40 255.255.255.0 hardware-address 0001.0002.0003 The snippet below, claims that hardware address can be used with bootp requests only. Logically, I feel that should be the case because bootp request doesn't have options field. In the case of DHCP request, the option 61 is used to carry client identifier. Hence, it seems, the IOS expect client identifies to be configured, if it a dhcp request. Comments please. Snippet from http://www.cisco.com/en/US/docs/ios/12_2/ip/configuration/guide/1cfdhcp.html#wp1001108 Router(dhcp-config)# client-identifier unique-identifier Specifies the unique identifier for DHCP clients. This command is used for DHCP requests. Router(dhcp-config)# hardware-address hardware-address type (Optional) Specifies a hardware address for the client. This command is used for BOOTP requests. With regards Kings
