PERMISSION_DENIED error while update configure in Tofino.

[남석현]

Hi, I'm using Tofino Webedge100bf-32 switch. Recently, I installed Stratum in my switch.

But I want to change the p4 program of stratum, so I tried two ways.

First, I tried to run P4Runtime with my p4 configure file, and I tried to run update_config.py in Stratum/hal/bin/barefoot. 

In both cases, I get the same error. The error code is PERMISSIO_DENIED.

How can I fix this problem?

Thanks a lot.

Have you confirmed that you are the master for the switch?

For example, by sending a master arbitration update:

https://p4.org/p4runtime/spec/master/P4Runtime-Spec.html#sec-master-arbitration-update

Also, which device ID are you using? BF-SDE default to 0, Stratum uses 1

If that doesn't work, please provide a little more details about the messages you are sending to/from the switch.

Thanks!

Brian

Oh, thanks. 
I changed election-id to 1,1 and it works.

But I get another error.

here is my command and error message.

$ ./p4runtime-sh-docker --grpc-addr 192.168.1.8:28000 --device-id 1 --election-id 1,1 --config ~/tofino/p4info.txt,int.bin

$ CRITICAL:root:Error when setting config

$ CRITICAL:root:P4Runtime RPC error (UNKNOWN): Error without message at stratum/hal/lib/common/p4_service.cc:365

I wrote p4info.txt and make int bin with tofino.py inside p4runtime-shell.

In switch, I installed Stratum and I run it with next command.

$ start-stratum.sh --bf_sim -bf_switchd_background=false

How can I fix my problem? Thanks a lot.
