Step 8 is the last step which is to boot the switch and verify that the switch successfully boots the IOS image placed into flash from xMODEM.

Note that when doing this you’ll need to disconnect your current console connection and change the baud speed on your terminal emulator from 115200 back to 9600. Once the boot parameter has been set you can now set the BAUD rate back to the default 9600bps by executing the command unset BAUD.
Cisco 3750 software update#
Once the IOS image is copied into flash you’ll need to update the BOOT parameter by executing the set BOOT flash:filename.bin command as shown below Transferring .bin.įile "xmodem:" successfully copied to "flash.bin" Switch: copy xmodem: flash.binīegin the Xmodem or Xmodem-1K transfer now. Once setting the BAUD rate and reconnecting to the console line of your Cisco switch you’re ready to copy the IOS image via xModem to the switch’s flash memory by executing the copy xmodem: flash:filename.bin and starting the xModem file transfer from the terminal emulator client as shown below However if you do not set the BAUD to 115200 your file transfer can take up to 3 hours.
Cisco 3750 software serial#
If you do this you’ll need to disconnect your console session and change the serial line speed from 9600 to 115200. To speed up the xModem file transfer speed you’ll need to set the console line BAUD rate to 115200 by executing the set BAUD 115200. Step 3 – OPTIONAL – If your image is corrupted you can format your flash file system by executing the format flash: command as shown below however this will delete your start-up configuration!!!Īre you sure you want to format "flash:" (all data will be lost) (y/n)?yįlashfs: flashfs fsck took 12 seconds. Once you’ve booted into Switch ROM mode you’ll need to initialize the flash file system by executing the flash_init command as shown below įlashfs: 0 orphaned files, 0 orphaned directoriesįlashfs: flashfs fsck took 10 seconds. The flash filesystem, and finish loading the operating The system has been interrupted prior to initializing theįlash filesystem. The password-recovery mechanism is enabled. Once you’ve booted your switch into Switch ROM mode you’ll be see the following dispatch īoot Sector Filesystem (bs) installed, fsid: 2īase ethernet MAC Address: 00:14:f2:d2:41:80 You can check out the required procedure by clicking HERE! This typically involves holding down the STAT button on the front of the switch when plugging in the power.
Cisco 3750 software series#
Unfortunately fixed configuration switches require the use of xModem to restore a corrupt or missing IOS images unlike the Cisco 4500 and Cisco 6500 Series supervisor engines which use compact flash cards

Recovering the Cisco IOS Image on a fix configuration Cisco Catalyst Series Switch is quite a bit different and more of an “old school” way of doing an IOS image recovery.

(This will remove your startup configuration) OPTIONAL – Format the flash file system if needed.
