Profinet (siemns PLC) on IR1101 Routers

[brcdk]

Hi all. Im about to set up an PLC from siemens, that uses Profinet protocol. 

It use a none standart protokol, wich has a bigger framsize.

normaly on our other switches and routers, i just make it a Trunkport, wich allow trafick on the specefik vlan:

switchport access vlan xxx
switchport trunk native vlan xxx
switchport trunk allowed vlan xxx
switchport mode trunk

but that dont seeam to work here. i can se on the intereface, that i have unknows protocols drops counting up.

I did also try make it a voice port, to support the larger frame:

switchport access vlan xx
switchport mode access
switchport voice vlan dot1p

but that aint working eighter.

does anyone have som surggenstion 

thx!

You are confusing switches and routers.

Routers don't have trunk ports, but do support dot1q subinterfaces to connect to switcheports configured for dot1q trunks.

What type of device + os are you trying to configure

hhmm its an 1101 Industrial Integrated Services Router.

switchport access vlan xxx                       <---- this command has no use on a port configured as a trunk
switchport trunk native vlan xxx
switchport trunk allowed vlan xxx
switchport mode trunk

1) making it a "voice port" does not enable larger frames? voice packets contain only 64 bytes payload!
you may need to enlarge the MTU-size instead 

2) what interface are you configuring? the IR1101 ports are FE? (=100Mbps) and what kind of port does your PLC have?

3) doing a quick search I found no reference to profinet support in the IR1101's specs,
you can use  the feature navigator https://cfnng.cisco.com/browse/iot/routers to search yourself
