on date 17th dec 2011 in the mention logs,  i found suddenly the switch CE-500 (in the given diagram) goes unexpected Reload that time only we observed the above mention logs, i also find-out there is no power traps that time.

i have gone through the cisco documentation relating to type-inconsistency and PVID-inconsistency but i did not found any solution relating to port-inconsistency, help me to get this solution if any where listed. or Please help me to find out the root cause for the same.

configuration relate to Attached Diagram.

3550 config:-

--------------------

# int fa0/20

switchport access vlan 15

switchport mode access

# int fa0/23

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 192,15,20

switchport mode trunk

STP Enable as PVST

-------------------------------------

Same configuration is on port gi1 on CE500 switch

------------------------------

Dlink switch 1 config :-

# int fa0/48

vlan allowed 192,20

STP disabled

----------------------------

Dlink switch 2 config :-

# int fa0/48

access vlan 15

int Fa0/20 of  3550 is connected to int fa0/48 of D-link

Native Vlan is 1 for all

Thanx for your Support.
