built a stack WS-C3750X-24S-E and WS-C3750X-24T-L

[Jan Krcmar]

Dear all.

We have a problem with a stack // two switches.

WS-C3750X-24S-E  &  WS-C3750X-24T-L

Both switches have the same IOS.

WS-C3750X-24S-E

**********************

Switch Ports Model              SW Version            SW Image

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

*    1 30    WS-C3750X-24       15.0(1)SE             C3750E-UNIVERSALK9-M

WS-C3750X-24T-L

*********************

Switch Ports Model              SW Version            SW Image

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

*    1 30    WS-C3750X-24S      15.0(1)SE             C3750E-UNIVERSALK9-M

The reason for the problem is different major version

*Mar  1 00:00:25.358: %STACKMGR-5-MAJOR_VERSION_MISMATCH: Major Version Mismatch (Local 1 - Received 6) with neighbor-0

*Mar  1 00:00:25.358: %STACKMGR-5-MAJOR_VERSION_MISMATCH: Major Version Mismatch (Local 1 - Received 6) with neighbor-1

WS-C3750X-24S-E

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

1        Master    0007.7d3c.b280          1.46        Ready

WS-C3750X-24T-L

How can we upgrade the WS-C3750X-24S-E to the same major version??

Thanks in advance for your help.

Firstly, stay away from 15.0(1)SE IOS.  It's got a memory leak like you can't imagine.

Try to use the 12.2(58)SE2 and see if you have the same issue.

Another thing, I believe one of your switch's product code ends with an "L".  I believe this model has an IP Base License while the other model with the "E" has a higher license and this could be the issue.

Can you please post the complete output for the command "sh license".

Hi.

you are right.

the WS-C3750X-24T-L 

Index 1 Feature: ipservices

        Period left: 8  weeks 4  days

        License Type: Evaluation

        License State: Active, Not in Use, EULA not accepted

        License Priority: None

        License Count: Non-Counted

and the WS-C3750X-24S-E

Index 1 Feature: ipservices

        Period left: Life time

        License Type: Permanent

        License State: Active, Not in Use

        License Priority: Medium

        License Count: Non-Counted

Index 2 Feature: ipbase

        Period left: 0  minute  0  second

I found now -->

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6406/data_sheet_c78-584733.html

The Cisco Catalyst 3750-X Series Switches with LAN  Base feature set can only stack with other Cisco Catalyst 3750-X Series  LAN Base switches. A mixed stack of LAN Base switch with IP Base or IP  Services features set is not supported.

Do you know ... if we upgrade the LAN Base to IP Base on the WS-C3750X-24T-L. Will the stack work?

Thanks.

Hi,

Yes, it will work.. All the other switches in stack should have the same ip base license and IOS

I have attached a document for your reference.

Hope this helps

Cheers
