For that moment where it's a work normaly

[s5700]display stp brief
MSTID Port Role STP State Protection
0 GigabitEthernet0/0/3 ROOT FORWARDING LOOP

Everything else is on Role DESI with Protection : NONE

but interface 0/0/3 isn't a main port.

What i understand someon on internal network doing loops so that is reason to a block transmission on port but not a shutting down interface.

Do somewhere in the logs (i dont know with log level) I can catch that action?

Hi,

I giving up. Didn't understand why he do it. Maybe it's a compatibility problem?

Maybe Huawei cant get along with a Cisco switches? somewhere I read it takes a lot depending.
About Spanning Tree Huawei switches use mstp where cisco has pvst by default - that is true?

In my problem i used a option on all FastEthernet ports spanning-tree bpdufilter disable. Only on GigabitEthernet i turn it on bpdufilter enable. Because in LOGBUF huawei switch say for that port it's a wrong bpdu pocket. In that case for a moth they (i mean s5700) no longer disable transmission. And S5700 remake port a ROOT role for a DESI in stp brief. On that configuration everything work fine!

but if i only remove bpdufilter from GigabitEthernet (but on all FastEthernet still have on all bpdu filter disable) for a 5 hours Huawei switch block transmission for cisco switch. And only one option to back transmission it's a shutdown port on Huawei switch and for a sec turn it on again.
