AM4376: Unable to modify the RSTP paramters.

Part Number: AM4376

Hi,

I am using AM4376 processor and along with that I have installed Processor SDK Linux 06_03_00_106 secure version. I referred below link for building the processor SDK. I have tested the RSTP functionality by referring the below link with our custom board and it is working.

https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Industrial_Protocols_RSTP.html

After executing the below command it got the details mentioned below.

root@am437x-evm:/home# mstpctl showbridge
br0 CIST info
  enabled         yes
  bridge id       8.000.88:01:F9:35:D9:A2
  designated root 8.000.88:01:F9:35:D9:A2
  regional root   8.000.88:01:F9:35:D9:A2
  root port       none
  path cost     0          internal path cost   0
  max age       20         bridge max age       20
  forward delay 15         bridge forward delay 15
  tx hold count 6          max hops             20
  hello time    2          ageing time          300
  force protocol version     rstp
  time since topology change 2561
  topology change count      0
  topology change            no
  topology change port       None
  last topology change port  None

I tested it with the default values mentioned above. But now i want to change the parameters of RSTP like

priority, hello time, path cost, forward delay , bridge forward delay, ageing time, enabled / disabled

How to change these since it is the required of our applications.

BR,

  • Hi,

    The mstpctl utility is included in the SDK but TI is not able to assist here with support of this application. It is beyond the scope of the low level driver support for the CPSW. 

    I did see this link that describes the options for the mspctl app, this page describes all the options you mentioned in your post.

    Best Regards,

    Schuyler
