Reloading a switch remotely challenge

[Peter Cilissen]

Hi,

We have a customer running some very old software 12.2(55)SE7 on 2960's.

We are facing multiple bugs within this release such as a TACACS single-connection problem.

Next to this, we are not able to ssh anymore, because the vty lines are not given free after exec-timeout has reached. Another bug within this release.

So the options left were:

- snmpset the correct OID to reload -> configparse error

- using kron -> kron config successfully pushed via SNMPset but logging shows "%Reload in progress"

We have tried to remove all the aaa/tacacs related config items because the TPLUS process is taking up to 99% CPU time. After that, using again kron, the same log message appears: "%Reload in progress"

Does anyone know how to kill this TPLUS PID or how to successfully reload a switch giving us "%Reload in progress" remotely?

thanks!

You may have another option to access the switch.

If you are able to access this switch via another switch which is attached to it and you know the access credentials than you could possibly try accessing it via its L2 mac address if the neigbouring switch supports clustering, which is a antiquated stacking feature no longer used but it could help in this situation.

1) Attach to the neighboring switch, if cdp isn’t enabled enable it and check is you can see the switch you wish to connect to
2) If the switch now listed enable clustering (if applicable)
conf t
cluster enable TEMP
exit

3) View candidates membersm You should now see your switch in this list
show cluster candidates

4) Add switch to be a cluster member
cluster member 10 mac-address <xxxx.mac of switch.xxxx> password YYY ( enable password of remote switch)

5) remote command onto switch
rcommand 10
