M4300 switch: port is down after reboot

[webernetz]

Hello community.

I'm facing the following issue: I have 3x M4300 switches in a circle. After rebooting (reload) one of the switches, some of those ports connecting to the other 2x switches are down. If I "shutdown" and "no shutdown" such a port, everything is up and running. For example, port 1/0/11:

(SWITCH) #show interfaces status all

                                         Link    Physical    Physical    Media               Flow Control

How can I troubleshoot this further?

M4300-24X24F ProSAFE 24-port 10GBASE-T and 24-port 10G SFP+
M4300-12X12F ProSAFE 12-port 10GBASE-T and 12-port 10G SFP+
Software: 12.0.17.13
Bootcode: B1.0.0.17

This is the only stuff I've seen in the logs:

(SWITCH) #show logging buffered

Buffered (In-Memory) Logging        : enabled
Buffered Logging Wrapping Behavior  : On
Buffered Log Count                  : 81
Buffered Log Threshold (lines)      : 160

Any hints for me?

Thanks a lot.
