Cisco cat 9404 configuration auto deleted

[saeedek]

I have 2 sw cat 9404 in virtual stacking after vss came up

I configured switches the configuration is automatically erased

This happens 2 times

I save configuration every time.

Check your confreg, issue "show version"

[UtkarshDewangan4753]

check if the rommon variable is bypassing the startup configuration

force the switch into rommon by pressing ctrl+c when it starts booting up

once you see the "switch:" prompt check for following

switch: set

check if you see following variable set to 1 in output

SWITCH_IGNORE_STARTUP_CFG=1

if you see the above then set it as 0 and reset

switch:SWITCH_IGNORE_STARTUP_CFG=0
switch:reset

 This should stop the switch from ignoring the startup config
