TDA4VH-Q1: TDA4VH Within the same VLAN group, bandwidth is limited to 100MB

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH

Tool/software:

Hi TI.

On the TDA4VH platform ethfw CPSW9G for SDK0900, the hostmacport, macport1, and macport2 are configured within VLAN8.

The physical interface connected to MACPORT1 operates at 100MB,

while MACPORT2's connected PHY operates at 1000MB.

During our bandwidth testing of MACPORT2,

we encountered a bandwidth limitation issue where the throughput was restricted to 100MB

TDA4VH LINUX run command"iperf3 -c 192.168.8.142 -u -l 1412 -b 1000M -t 50" for UDP, However, TCP can reach 1000MB.

During UDP transmission, the count of octestframes1024 on MACPORT1 (0) increases sharply as MACPORT2 (1) grows.

  • Hi,

    I could see in between throughput is higher and dropping, are you performing any data transfer in between Host Port to MAC Port-1.
    Also, can you please confirm the throughput test is with unicast frames right.

    On the TDA4VH platform ethfw CPSW9G for SDK0900, the hostmacport, macport1, and macport2 are configured within VLAN8.

    Can you please check the same without VLAN as well.

  • HI dorela,

    I could see in between throughput is higher and dropping, are you performing any data transfer in between Host Port to MAC Port-1.

    -> NO, the Host Port to MAC Port-1 data growth is caused by the data flow generated by this command “iperf3 -c pc2_ip_address -l 1412 -b 1000MB -t 50”

    Also, can you please confirm the throughput test is with unicast frames right.

    -> yes,iperf3 -c pc2_ip_address -u -b 1000MB -l 1412 -t  50

    Can you please check the same without VLAN as well.

    -> ok,i will chek

  • Hi,

    Can you please check the same without VLAN as well.

    -> ok,i will chek

    Sure, Please check any Port Mask drop in this case.

    Only possible scenario will be ALE aging, If PC2 MAC address learned was lost then packet will be flooded to both MAC Port-1 and MAC Port-2 as both are part of same VLAN.

    Also, ensure PC1 and PC2 has different MAC addresses.

    Sudheer

  • Hi dorela,

    This issue can also be reproduced without VLAN

  • Hi,

    This issue can also be reproduced without VLAN 

    It can be due to Host Port VLAN, it will get added to the packet while processing internally and untagged while egressing the packet.

    Can you please run ping test from PC2 to Linux client while running the test and check any drops in throughput?

    Best Regards,
    Sudheer

  • Hi doredla,

    When testing the bandwidth from PC2 to the Linux client, the speed is normal at 900MB

  • Hi,

    The test results from the Linux client to PC2 show that the bandwidth is often limited to 100MB, but sometimes reaches 900MB.

    As i informed earlier, It might be due to aging of PC2 MAC address.

    Can you please run normal ping as well along with iperf client from Linux client to PC2.

    Can you also check by dumping ALE entries while observing high throughput and less throughput, and share with us along with ifconfig info of PC1, PC2, Linux client.

    Best Regards,
    Sudheer

  • Hi,

    Simultaneously performing ping and iperf3 bandwidth tests shows normal results

    Also, check that there will not be a jump in Port-1 statistics.

    Usually Aging period is 1sec. If no data is received from the peer side MAC entry will be lost from the ALE post aging interval.

    When you are running ping simultaneously along with iperf3 UDP, PC2 is sending back ping responses to the Linux client, so PC2's MAC entry exists in ALE and has not expired.

    The same in case of TCP, as it was acknowledgment-based communication, PC2 sends some ACK for the traffic, so, MAC entry will not age.

    Can you also check by dumping ALE entries while observing high throughput and less throughput,

    You can confirm this by dumping ALE table entries in the above scenarios. 

    Best Regards,
    Sudheer
