The company I work for has some Cisco hardware in the plant and, as our team has no expertise on configuring Cisco switches I hope you can help me and my team to get this problem solved. I will make a brief comment on what is going wrong here:

I own two SG300-28 and they are connected using LAG over 2 interfaces (GI27 and GI28) but this is not the problem, I think, just the scenario. So I have two sides:

CSC <--- LAG ---> TOO

At CSC I have no problem and the switch is running fine for 38 days (we had a hard reboot back there).

On the other hand, at TOO, we are facing a soft reboot problem and we are not able to fix it. The only message we got, just before the reboot is:

2147476226          2013-Dec-09 06:20:05          Emergency           %AUTOSMARTPORT-F-DEV_CALC_FAILED: XDP device type calculation failed: interface gi21 - capability 2 ***** FATAL ERROR *****  Reporting Task: NCDP. Software  Version: (date  10-Oct-2013 time  17:15:41) 0x16adbc 0x166f28 0x6df2b0 0x48fad8 0x4903e8 0x490608 0x6e8490 0x6e8528 0x6e8d90 0x82eb24 0x831 7b8 0x837a88 0x1223f0 ***** END OF FATAL ERROR *****

After reboot:

2147483510          2013-Dec-09 06:26:29          Warning           %CDP-W-NATIVE_VLAN_MISMATCH: Native VLAN mismatch detected on interface gi21.

And the switch reboots. This is causing us a lot of problems. As an emergency exit (and it's not fully working) we disabled AutoSmartPort (which is a functionality we will never use in the network layout so we don't need it).

Is there anything you can tell me to do? I am attaching running config for TOO. Befero someone ask we already tried to change the hardware (we own a spare SG300) and the same problem is there.

Best regards,
