Omnet crashing on hasGcl = true

[paintspot87]

I'm trying to implement TSN time aware shaper with a GCL similarly to how I've done it on a real switch where I would define time-slots and what gates are open in that time-slot. Rather than defining durations per gate as in the showcase.

When I run the modified inet\showcases\tsn\trafficshaping\timeawareshaper showcase with *.switch.eth[*].macLayer.queue.hasGcl = true it just crashes and no matter what configuration I'm trying it just crashes.

I'm running omnet 6.0.2 with INET 4.5.2 on Windows 10.

Any ideas?

This is the .ini-file:

This issue is already fixed in the INET master branch.

@Frt0214 It was solved by using the master branch as levy said.

Personally I just replaced

GateControlList.cc
GateControlList.h
GateControlList.ned

and it works now.

@paintspot87 The mistake is no longer happening. Thank you for your help!

@levy @paintspot87 , hi ! Above is one of my gating configurations. When I set hasgcl to true, can I configure the offset parameter for the gcl entry? The offset parameter of the entire table appears to be missing. It appears that the offset parameter is invalid. In other words, how do I make the entire entry run after the offset value?

Best Regards

[Frt0214]

Just like basetime>currenttime indicates that the gate entry is running

There's no offset parameter in GateControlList and you cannot set the offset parameter of PeriodicGate modules when using the GateControlList.
