stacking problem in X670-G2

[omar_khaled]

Hi There

We have two X670G2-48x-4q and want to stack them to each other. we use V160 and easysetup according to following document. (EXOS version, License Level and Active Partition are same)

https://extremeportal.force.com/ExtrArticleDetail?an=000080493

we encountered some problems. after enable stacking switches (some time one of switches) crashes and goes reboot.

some of logs listed here:

unconfigure dispatch attach fail: bcm_attach client unit 9
Unable to set ECMP hash= 0 for slotNo 2 unit 9, â 0 rc -19
Slot-1: Slot-2 down, resetting all TCP connections to it
Slot-1: Module in Slot-2 is removed
Slot-1: initBCMChipTempSensors : Failed to initialize chip temperature sensors for slot Slot-2
Slot-1: ERROR4: attaching driver to slotNo 2 unit 0 remote 9, rc=-19
Slot-1: Unable to set L2/L3 Hash = 5 for slotNo 2 unit 9, rc -19

default EXOS version is: 15.6

we cleared NVRAM, upgraded to EXOS 16.1.3.6-patch1-9 and 16.1.3.1-Patch1-7 but again not works (crash and reboot).

please tell us which EXOS is compatible with stacking and what we should do.

Regards.

Hi Chacko,

EXOS 16.1 is currently recommended for the X670-G2 switches, but the new 21.x and 22.x versions can be used as well.

Please see http://www.extremenetworks.com/extreme-hardwaresoftware-compatibility-recommendation-matrices/softwa...

Dear Omar,

is it right, that you use the 16.1.3.6 on the X670-G2?
I think only the new 21.X or higher is supported on that one.

Best Regards
Chacko

Do all of the switches contain all the same licenses Have you tried building a stack with just with the.same image installed ( no configuration at all)

Could you please open a GTAC case? So we could analyze/troubleshoot further.
