I stupidly wrote a config to startup that meant I have no access to the config anymore.
I tried factory resetting the node by using the physical button on the front - Holding it in for three seconds until the lights flash, then keeping it held in for another 7 seconds (I also tried varied time lengths, up to minutes at a time) at which point the node is supposed to reboot into a config-less mode. This doesn't work.
I also tried holding the mode button down as the switch powers up.
The commands I ran before saving are below. No access via "Aux". SSH only over Console (Is that even possible?). And the only IP address is on VLAN 115, which is not attached to any ports.
Can anyone tell me how I might possibly fix this?
! =======Go to Privileged Mode
config t
! =======Set the hostname
hostname ExternalSwitch
! =======Set the password to access Privileged Mode to 'privpass'
enable secret privpass ! - NOTE: 'secret' creates an encrypted password to access the privileged mode
! =======Edit Console settings
line con 0 ! There is only one Console line.
password consolepass ! Password to be changed - but will not be used.
login ! Specify that you must log in if using this line.
transport input ssh ! Only allow SSH through the Console line.
exec-timeout 5 0 ! Revoke privileges after 5 minutes and 0 seconds of inactivity (Default is 10 minutes).
exit ! Stop editing settings for this line.
! =======Edit Auxiliary settings
line aux 0 ! There is only one Auxiliary line.
password auxpass ! Password to be changed - but will not be used.
no login ! Specify that this line cannot be used as we have no Aux Port. Security measure only.
exit ! Stop editing settings for this line.
! =======Edit vty settings - These are what will be used 99% of the time.
line vty 0 15 ! There are 16 vty lines, 0 to 15.
password nologinpass ! Password to be changed - but will not be used.
no login ! Specify that these lines cannot be used as security measure. We will activate 2 lines next
exit ! Stop editing settings for these line.
line vty 0 1 ! Now edit two vty lines. We have no need for more than two people to log in at once. This edits vty line 0 and line 1.
password vtypass ! Password to be changed - but will not be used.
login local ! Specify that you must log in if using this line. Local means you will use a local username - Required for SSH log in.
transport input ssh ! Only allow SSH through the VTY line.
exec-timeout 5 0 ! Revoke privileges after 5 minutes and 0 seconds of inactivity (Default is 10 minutes).
exit ! Stop editing settings for these line.
! =======So far, the line passwords are not encrypted.
! =======The next line encrypts all plain-text passwords.
service password-encryption
! =======Warning message to be shown BEFORE logging in.
