  • Actually, that is the OS (IOS). The ROMON is more akin to firmware. I don't think you would call Windows firmware; more likely, you would call the BIOS firmware. – Ron Maupin May 25 '16 at 14:32

Source Healthy Switch : A

Destination Unhealthy Switch : B

On the A switch;

A(config)#tftp-server flash:/c3560-ipbasek9-mz.122-58.SE2/c3560-ipbasek9-mz.122-58.SE2.bin

On the B Switch ;

Enter the Rommon (Hint: Ctrl + Brk)

rommon 1> set

rommon 2> IP_ADDRESS=192.168.X.X (B Switch IP address Temporary)

rommon 3> IP_SUBNET_MASK=X.X.X.X (B Switch Mask)

rommon 4> DEFAULT_GATEWAY=X.X.X.X (Default Gateway IP)

rommon 5> TFTP_SERVER=X.X.X.X (A Switch IP address)

rommon 6> TFTP_FILE=c3560-ipbasek9-mz.122-58.SE2.bin

rommon 7> tftpdnld

Invoke this command for disaster recovery only.

WARNING: all existing data in all partitions on flash will be lost! Do you wish to continue? y/n: [n]: y

rommon 8> reset

  • I'm not too sure if tftpdnld is available in some of the Cisco switches. As a backup you may have to use a serial console to transfer a file to your switch using xmodem transfer. Link:- community.spiceworks.com/how_to/… – user4565 May 25 '16 at 21:21
