9200 stack reboots itself

BorislavPenchev0962 · ‎06-22-2021

Hi,

we noticed after few days reboot occur on only one stack of 6 x 9200 Switches

Reload Reason Switch 1: stack merge
Reload Reason Switch 2: stack merge
Reload Reason Switch 3: lost both active and standby
Reload Reason Switch 4: lost both active and standby
Reload Reason Switch 6: lost both active and standby

then Switch 5 become the new Master. Switch 5 is not rebooting.

Switch Ports Model SW Version SW Image Mode
------ ----- ----- ---------- ---------- ----
1 52 C9200L-48P-4X 17.05.01 CAT9K_LITE_IOSXE INSTALL
2 52 C9200L-48P-4X 17.05.01 CAT9K_LITE_IOSXE INSTALL
3 52 C9200L-48P-4X 17.05.01 CAT9K_LITE_IOSXE INSTALL
4 52 C9200L-48P-4X 17.05.01 CAT9K_LITE_IOSXE INSTALL
* 5 52 C9200L-48P-4X 17.05.01 CAT9K_LITE_IOSXE INSTALL
6 52 C9200L-48P-4X 17.05.01 CAT9K_LITE_IOSXE INSTALL

Configuration register is 0x102

this has been tested with no change - still reboots on16.9, 16.12 and 17.5

do you know what would be this coming from ?

Regards

Boris

Please post the complete output to the command "dir".
NOTE: Remove only the switch name. Leave the rest alone.

Can you post show run and show switch. make sure stack ring is ok and 100% can you post some logs if you have any ?

we noticed after few days reboot occur on only one stack of 6 x 9200 Switches

is the stack automatic rebooting ? or only 1 switch ?( i would not advise go to 17.5 ) i would be happy if you can be 16.12 .X or 17.3.X

we are currently not able to follow the exact order of reboots, but l think we found something in regards to the stack ring(marked in red), is this related to the stack cables or stack modules ?

- Check the Stack Cabling , verify that all connections are solid and good.

When you get chance, worth to turn off the whole stack, and reseat the cables and test

- Check the logs when this happens, preferably use a syslog-server, so that logging can be monitored at all times, sometimes production-situations and corresponding info's can be indicative of an upcoming problem and or 'last gasp' information may also get logged on the syslog-server.

we switched stack cables from 3/2 to 2/2 and seems this has resolved the issue.

thanks all

Glad all good, we were suspected Physcal cables as before.
