bpdu-restrict doesn't work (PVST+) on EXOS

Userlevel 4
Hello, everybody!

I can't make port to be disabled after it receives BPDU. I've connected the port to C2960 and it is still forwarding regardless it's access or trunk port on cisco.

Please, take a look at my confs:


configure stpd V12 ports mode dot1d 3:10
configure stpd V12 ports link-type edge 3:10
configure stpd V12 ports edge-safeguard enable 3:10
configure stpd V12 ports bpdu-restrict enable 3:10

Could you please tell me what is wrong? I can provide all additional information required.

Many thanks in advance,

Well, the solution was found. Russian engineers at distributor company investigated:

You should disable/enable to activate bpdu-restrict feature in PVST+/dot1w mode.

It would be rude to share my thoughts now...
