Netbooting from the ROMMON

Netbooting using a boot loader image is not supported. Instead, use one of the following options to boot an image:

1. Boot from a CompactFlash card by entering the following command:

rommon 1> boot bootflash:<bootable_image>

2. Use ROMMON TFTP boot.

The ROMMON TFTP boot is very similar to the BOOTLDR TFTP boot, except that:

- the BOOTLDR variable should not be set

the TFTP server must be accessible from the Ethernet management port on the supervisor engine.

To boot from ROMMON, perform the following tasks while in ROMMON mode:

a. Ensure that the Ethernet management port is physically connected to the network.

b. Verify that bootloader environment is not set by entering the unset bootldr command.

c. Set IP address of the Ethernet management port on the supervisor engine by entering the following command: set interface fa1 ip_address> <ip_mask

For example, to set the supervisor engine Ethernet port with an IP address 172.16.1.5 and IP mask255.255.255.0, enter the following command:

rommon 2> set interface fa1 172.16.1.5 255.255.255.0

d. Set default gateway for the Ethernet management port on the supervisor engine by entering the following command: set ip route default gateway_ip_address. The default gateway should be directly connected to the supervisor engine Ethernet management port subnet.

e. Ping the TFTP server to ensure that there is connectivity to the server from the Ethernet management port on the supervisor engine by entering the following command: ping <tftp_server_ip_address>.

f. Once the ping is successful, boot the image from the TFTP server by entering the following command: boot tftp://tftp_server_ip_address>/<image_path_and_file_name

For example, to boot the image name cat4500-is-mz located on the TFTP server 172.16.1.8, enter the following command:

rommon 3> boot tftp://172.16.1.8/tftpboot/cat4500-is-mz
