The DHCP options can be configured with the option code ascii string tftp-server-name command. If you do not have the name of the server and if the server is configured only with the IP address, then use the option code ip ip address command.

I am in the process of try to localize our dhcp services from our server at remote data center to a local cisco MLS for nec ip 700 series phones. I have picture of the options set on the server. The options in particular I need help with are options 141,151,152,153, and 163. I need help on how I would convert those options to switch.

I think tag is an option code (option name or number in table of options). i.e 53- dhcp request; 61-client id; 12- host name, 81-FQDNS, 60-vendor id, etc. tag octet- not sure why they call octet; maybe it comes from fact that number identifying option code is within 8 bits or 2 Hex (like FF or decimal value 255.

I'm going through DHCP and I came across these two concepts: "next-server" and "tftp-server-name" that confused me. Cisco Docs says the following about "next-server": Configures the next server in the boot process of a DHCP client. But what is meant by "in the boot process" here? It's hard for me to imagine how this is happening at the moment..

DHCP Options is just something many people use to control the DHCP-process. You need to first figure out what you want to achieve with the DHCP-options. For example to identify a specific access-point platform using DHCP-option 60 then Cisco specifies that the 3600-AP requires ASCII-format with " " quotes for it to work.

Please explain me last line . ip dhcp pool CORP-WIRELESS . network 192.168.5.0 255.255.255.0 . default-router 192.168.5.1

DHCP option 82 is only used by a DHCP relay agent. It is the field that is the first 8-bits int the 64-bit 'DHCP options' field of the DHCP request packet sent by a client. When it is set to 'code 82'.

It seems obvious now, but if you're learning the DHCP process, think of DORA: Discover - Client broadcasts a message to discover a DHCP server. Offer - DHCP servers offer an IP address. Request - Client selects an offer and formally requests to use the IP. Acknowledge - The Server formally allocates the IP (and options) to the client

3.) In production networks options 60 rarely ever makes sense to use. The rules are that if option is defined the DHCP server will only give out the option 43 if the VCI provided by the DHCP client matches what the scow is configured for.

About "options" in DHCP, maybe you can see about option-82 and basic labs for Cisco Collaboration (option-150), but in CCENT exam I don't see about it. Here are some links about DHCP option .
