TFTP is a UDP-based function.Frames may be lost in transit. If this occurs, and the Start-Up Action is not set to Try boot once, lost frames can cause the boot process to continuously retry without success. Set the Start-Up Action to Try boot once to avoid this situation.

6Enter 1 to select the Boot Device option, and enter 2 to set the Boot Device to Network.

You are then prompted to set the slot number and boot filename.

If you have a 4-Slot chassis, your options are 1 through 4. If you have an 8-Slot chassis, your options are 1 through 8.

For example:

/image/NBII/SW/101/FF/boot.29k

You do not need to specify the /tftpboot directory because the TFTP server assumes the /tftpboot directory by default.
