To use BootP with your Catalyst 3920 complete the following steps:
Step 1 Edit the BOOTPTAB file on the BootP server. For more information, refer to the "Editing the BOOTPTAB File" section.
Step 2 Initiate the BootP daemon (BOOTPD) on the BootP server.
Step 3 Make sure that the IP State in the IP Configuration Menu is set to BootP When Needed or BootP Always. For more information about IP configuration, refer to the "Configuring IP Information" section of the "Configuring the Catalyst 3920" chapter.
Step 4 Initiate the BootP transfer by resetting the Catalyst 3920. A BootP request is automatically initiated after diagnostics are completed.
Note Do not configure multiple BootP servers to a single Catalyst 3920.

Define Different Master Entries for Each Catalyst 3920 (or Domain).
Catalyst 3920 Domain 0:\
hn:\
ht=token-ring:\
vm=rfc1048:\
ha=0004AC29AEE0:\
ip=134.177.169.111:\
sm=255.255.0.0:\
gw=134.177.169.201:\
bf=/etc/"cat3900-main-gz.x-y-z.bin:"
Modify or create a BOOTPTAB file to include information for each Catalyst 3920 served by this BootP server. Specify the following information:
Hardware address (ha)—Enter the MAC address associated with the domain. If you do not know the MAC address for the domain, view the Master Address Table (refer to the "Viewing Address Tables" section of the "Managing the Catalyst 3920" chapter). Do not use the MAC address in the Switch Information panel.
IP address (ip)—Enter the IP address to be assigned to the domain.
Subnet mask (sm)—Enter the subnet mask to be assigned to the domain.
Gateway address (gw)—Enter the gateway address to be assigned to the domain.
If the Catalyst 3920 has been configured for multiple domains (VLANs), a BootP server must be attached to each configured domain and the BOOTPTAB file on the server should include the information specific to that domain.
When the virtual switch function is used and BootP configures the IP address of the BootP-connected network.
Some BootP implementations do not need or handle any BootP extensions.
The BootP function might not work if BootP request and reply frames must cross Token Ring segments.
BootP has a limitation with respect to the gateway entry. The server device IP address is written into the gateway (gw) address field when the configuration is downloaded. Thus, you must configure the gateway address on the Catalyst 3920 at the end of the download sequence. Refer to your UNIX operating system environment manual for further information.
