WS-C3850 reload automatic

[tianwen]

A few days ago. After the switches reload the master had changed.

show version:
Switch Ports Model              SW Version        SW Image              Mode   
------ ----- -----              ----------        ----------            ----   
     1 16    WS-C3850-12XS      03.07.04.E        cat3k_caa-universalk9 BUNDLE 
*    2 32    WS-C3850-24S       03.07.04.E        cat3k_caa-universalk9 BUNDLE 
     3 56    WS-C3850-48T       03.07.04.E        cat3k_caa-universalk9 BUNDLE

3       Standby  08cc.a77f.2680     4      V07     Ready  

Switch2 is active now. The Master supported to Swithc1. And  I saw a message in show logging :

DHCP pool voice-pool configuration on Active is not matched on the Standby.

Then I changed the DHCP configuration in configure terminal 

So I saw another message:

%PLATFORM_HA-4-RELOAD_PEER: Reloading the Standby, due to Config-Sync (Configuration mismatch)

The Switches  reload automatic, It just scare me.

I don't know why The Switches reload automatic ,I just changed some conf

sw#sho switch
Switch/Stack Mac Address : 2c31.242d.a180 - Local Mac Address
Mac persistency wait time: Indefinite
H/W Current
Switch# Role Mac Address Priority Version State
------------------------------------------------------------
*1 Active 2c31.242d.a180 15 V02 Ready
2 Member 2c86.d219.6380 8 V03 Ready
3 Standby 08cc.a77f.2680 4 V07 Ready

Now the Switches are back to normal and I don't see any Active is not matched on the Standby in show logging.

But I am afraid changing conf of switch,now

Hi,

It looks like a bug "CSCuy96474". Upgrade your firmware.

Thank you for your reply,

but our switch is 3850 not 3650, Is that the same bug?

Hi,

I checked but advised to upgrade the version.

Thank you. What version I support to upgrade? 

Because the 3850 is our core switch. it need to 24-hour online .

1. It doesn't have to be "exactly" an aaa config that can trigger the bug. The Bug ID, with little useful info it may have, means that simply doing some commands can/will cause the config not to sync across the stack. A bug.
2. 3650 & 3850 share the same code.

If in doubt, raise a TAC Case.

Thank you, I see . so how to fix this bug? Is that need to upgrade the version ?

The 3850 is our core swith. it need to 24-hour online .

I don't see any "Active is not matched on the Standby " in show logging so far  . I want to confirm that if I changed the conf now  will these message shows up again?

Because I am still afraid.........
