Profinet and IE4000/IE5000

[HUBERT RESCH]

Hi according to the documentation on IE5000/IE4000 Profinet is enabled by default on VLAN1, changing the Profinet-VLAN with
"profinet vlan xxx" is supported.

so my question is, what happens when configuring the "profinet vlan xxx"
Are there happen other things like QOS as well in the background when configuring profinet vlan xxx, ore do I have to configure QOS on uplink-trunks so that  CS6 marked packets are prio

I assume that on access-ports of the profinet VLAN packets with VLAN-ID=0 are accepted , correct ?


Whats confusing me is that documentation says that we can only have ONE profinet vlan per switch.

when changing the profinet vlan, you need to ensure that the Profinet vlan is a member vlan on all 'trunk' links.  this means the new profinet vlan should be a permitted member on the trunk.

no change to QOS is needed.  the QOS policy is not vlan based.

the Cisco IE switches can be managed via Profinet.  and only Profinet vlan can be supported at a time.  its purely a Profinet mgmt restriction.  not a Layer 2 switching restriction.
