Did you read, that fix script is for OLD units
OK so OLD switches:
WS-24-400
WS-24-400A
WS-12-250A
WS-8-250-DC (the old original ones with flat SFP stack)
May have a problem as in the bneginning we did not include boardrev in the config so they will have problems but they are 10 year old switches
There is a fix:
Connect console cable:
drop to linux with CMD command
Cut and paste this into console:cmd
cat<<EOF>cfgfile
MAC=EC:13:BX:XX:XX:XX <= NOTE MAKE SURE MATCHES ORIGINAL MAC
----MODEL=WS-24-400
----MODEL=WS-24-400A <=USE WHAT YOUR MODEL IS
----MODEL=WS-12-250A
BOARDREV=X <=USE WHAT YOUR BOARD REV WAS BUT IF UNSURE USE "B"
SERIAL=0
EOF
mtd write cfgfile config
reboot [CR in paste or Enter at end]
A WS-12-250-DC is NOT an old unit
If the switches are power cycled during upgrade you can brick the unit. Some people use a smart power strip that will reboot a switch if pings stop. This upgrade process can take longer than normal due to a lot of house keeping from the vast changes in code. So if the unit is power cycled during the upgrade it is bricked. Make sure to disable this or increase time missing pings till reboot 10 minutes or more. I know this as I had this issue on one of my towers using a smart power strip. You might be bale to recover it via console cable in your lab there is a post on here that details how.
We upgraded many WS-12-250-DC units as well as EVERY unit we ever built with no issues.
Here are some post detailing this recovery process:
