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 Jason, thanks for your answer.

All of switches contain same lenience: Advanced Edge

I installed EXOS with same image and form Bootrom.
(it installed on primary and secondary partition)

with any configuration again occurs some errors.

Hi. it seems you already tested recommended firmware. I suggest to open ticket with GTAC. They will investigate what is wrong, what is the root cause. Can be faulty device, can be unsupported tranceiver/cable... Z.

thanks for your answer.

after some tests i found this devices doesn't work properly. for example in none-stack with default configuration broadcasting doesn't work.

i should ask in another post.
