Cisco 6506 rebooted

[Nikhil Srivastava]

Hi,

My Cisco 6506 switch got rebooted with the message as below:

%SPANTREE-5-EXTENDED_SYSID:

Configured from memory by console

System restarted...

Can any one suggest the root cause. Logs attached.

Thanks,

Hi,

Try re-seating the module 6.If it works then fine orelse open a TAC.

Thanks

[Nikhil Srivastava]

switch is working fine but want to analyse the actual reason for reload.

[Reza Sharifi]

what type of module is in slot 6?

[Nikhil Srivastava]

It is WS-SUP720-BASE

[Reza Sharifi]

so you have 2 sups with redundant sup in slot 6?

if yes, are they in redundant SSO mode?

[Nikhil Srivastava]

Only two modules are there WS-X6724-SFP in slot 2 and SUP720-Base slot 6

Is that all?  You want answers as to why the chassis rebooted and this is the only information you can furnish?

[Nikhil Srivastava]

Sh tech support of the device is already attached.

[Leo Laohoo]

Cool!  More information.

Here's my take (until Reza and others can chime in) ...

1.  You are running IOS SXH1.  This IOS has been released sometime early 2008.

2.  The version of IOS you are running has been removed by Cisco possibly because there are some glaring bugs.

3.  The crash happens after the log entry:

• Nov 27 17:44:21 IST: %FABRIC-SP-3-DISABLE_FAB: The fabric manager disabled active fabric in slot 6 due to the error (2) on this channel (FPOE 4) connected to slot 6
• Nov 27 17:44:21.098 IST: SP: Supervisor has bad local fabric channel. StbyRdyForSwOver 0, StbyLocalFabLinkOk 0

My recommendation is for you to upgrade your IOS to something more "current".

In addition to Leo's good recommendation and to eliminated any fabric channel hardware issues, move the sup to slot 5 and see if the issue reappears
