Hello,
I have a problem with siemens industrial profinet apparatous and my Cat2960.
Siemens host can be pinged without any problem but they are not able to do any other kind of traffic.
If i look at the interface I can find that all ingress packet are UNKNOWN DROPPED.
I found a document where si explained that "probably" siemens host are using packet with 802.1p header and vlan 0.
I tried the following tests:
1) port in access mode - failed
2) port in trunk mode with native vlan - failed
3) port in access mode with voice vlan - failed
4) port in acess-mode with voice vlan dot1p - failed
Did you never had such this problem?
can anybody help me?
Thanks
Johnny
