Verified bootflash:packages.conf
Since the switch recognizes all Flash devices in ROMmon mode, you can issue the dir device-name commands
to show the Flash contents, as is demonstrated in the remaining sections of this document
Notice in the previous example, there is only a single boot image in bootflash. You can have as many system
images as you can fit in the bootflash:. Bootflash size is fixed at 64 MB.
The following are the ROMmon variables that Catalyt 9400 supports and examples to set them:
• MANUAL_BOOT=yes
A value of "yes" disables auto boot and enables manual booting. A value of "no" enables auto boot.
• DEFAULT_GATEWAY=172.27.74.1
• IP_ADDRESS=172.27.74.111
• IP_SUBNET_MASK=255.255.255.0
• TFTP_SERVER=172.19.64.31
Recover Switch from a Corrupt or Missing Image in ROMmon
Mode
The switch could wind up in ROMmon mode due to these reasons:
1. A switch reload or crash after the image was corrupted or deleted. See the Recover from a Corrupt or
Missing Image section of this document for more information..
2. See the Recover from a Continuous Reboot section of this document to determine if a valid system image
is present in the bootflash:. If there is no file present, see the Recover from a Corrupt or Missing Image
section of this document.
3. The boot variable is incorrect, but a valid image is still present. See the Recover from a Continuous Reboot
section of this document for more information.
These primary symptoms occur in your network if the switch is in ROMmon mode:
• Routing failures occur because ROMmon mode cannot route between VLAN interfaces, and is only
designed to recover the switch.
• If you try to Telnet to any of the interfaces it fails, and if you are connected to the console port of the
Supervisor, you see this prompt:
