New 2960S switch - refuses to join existing stack, possible license issue / corruption / etc.

Howdy,

I inherited a stack of 2x 2960s-48lps-l switches. I am trying to add another switch to the stack, so I purchased a 2960s-48ts-l switch and the appropriate FlexStack module after I learned about the process. It looks like the new, unconfigured switch should just dutifully jump in to the existing stack. It hasn't so far.

Here is what I have done:

  • Read the chapter on switch stacking start to finish
  • Updated the firmware of all switches, so they are identical now
  • Set the current master priority to 15 and the other existing switch to 10
  • Plugged in stack cables
  • Tested individual stack cables and modules with the existing stack members - they are all good
  • I tried just letting the new switch join organically
  • Then I tried provisioning from the master and booting the new switch
  • More than once, I removed the configuration of the new switch before restarting it just to be extra certain

In all cases, the new switch decides it is its own master in a stack of one, although it curiously assign itself stack member number 3 (the existing stack members are 1 and 2). The port status of the FlexStack modules shows down on all connections between the new switch and the existing stack, and the stacks otherwise give me no clue that they are remotely aware of each other.

In my evaluation, I noted an oddity on the new switch that I think may have some importance (but possibly not)... when I check the licenses, I get this:

Airco-2960-n1#sh license
Index 1 Feature: lanlite
        Period left: 0  minute  0  second
Index 2 Feature: lanbase
        Period left: 0  minute  0  second

If I am not mistaken, one or the other should be licensed, and the one that is definitely licensed to this switch is lanbase. On the stacked switches, this is the result:

Airco-2960#sh license
Index 1 Feature: lanlite
        Period left: 0  minute  0  second
Index 2 Feature: lanbase
        Period left: Life time
        License Type: Permanent
        License State: Active, In Use
        License Priority: Medium
        License Count: Non-Counted

So, I think these are the questions I should ask:

Did I screw something up, causing the license status to be 0 and 0?

Is there some configuration of which I am unaware on the stack that would prevent the normal behavior of a new switch joining the stack?

Forgive my ignorance... I am usually the one answering forum questions, not asking for help. I will gladly include any additional information you might need in order to help determine the appropriate course of action.

Many thanks!

Hi Derek,You seem to have

Hi Derek,

You seem to have done everything right to add this new switch to the stack.

From the output you provided, the only thing I can see is that the new switch does not have the proper license to match the existing ones. The other way to show if you have the correct license installed is by issuing "sh version".  This command usually shows the current license and what it will be the next time you reboot the switch.

So can you post "sh ver" from the stack and the new switch?

HTH

Derek,You have a corrupted

Derek,

You have a corrupted license on the 2960s-48ts-l. It has lanbase by default. Verify the outputs with

 

sh lic file

switch(config)#license save flash:lic.xml    ---> to check license info for example:

% Storage read success but LicenseInfo failed Invalid file

No license entries in license storage

If so you may need to either opening a TAC to request a rehost of the license or engage your provider assistance.

Just to conclude this thread,

Just to conclude this thread, I will explain what happened next.

I replaced the firmware in the unit with 15.2(1)E3, which was the previous release, and at that point, everything just worked. It was glorious. As I stated previously, I don't really know what I am doing, so I probably downloaded the wrong firmware previously.

So again, the switch is working in the stack just fine now, and that is just awesome. However, the license still displays this:

Airco-2960#remote command 4 sh lic
Switch : 4 :
------------
Index 1 Feature: lanlite
        Period left: 0  minute  0  second
Index 2 Feature: lanbase
        Period left: 0  minute  0  second

Bah, oh well, as long as it works.

Thanks to those who replied with suggestions!
