LS1028ARDB switch port ping failed

[yyu2]

Hi all,

I install the O/S on the board with configuration of nxp_ls1028ardb-64b_defconfig.

When back-to-back connectinig the eno0 port to another PC, I can successfully ping. But if connecting the swp0 to another PC, the ping fails. what is reason? I thought swp0 should be connected to eno2 and then to CPU.

Best,

Ok, I miss configuring the ip address for eno2. After doing that, it successfully ping from swp0 to remote host.

Hello Yi Yu,

Please run the configuration script first on the switch as the following. You could refer to the section "CPU port without bridge" in LSDK user manual for details.

#!/bin/bash
#
# Simple switch configuration without bridge
# Assume both ENETC and Felix drivers are already loaded
MAC_ROOT=bc:8d:bf:7c:5b
swpip=192.168
# Configure switch ports
swps=($(ls /sys/bus/pci/devices/0000:00:00.5/net/))
let nr=${#swps[@]}
for (( i=0; i<&nr; i++ ))
do
ip link set ${swps[$i]} address $MAC_ROOT:$(echo "${swps[$i]}" | tr -dc '0-9')
ip addr add ${swpip}.${i}.1/24 dev ${swps[$i]}
ip link set ${swps[$i]} up
done
# bring up ENETC Port3
seth=$(ls /sys/bus/pci/devices/0000:00:00.6/net/)
ip link set $seth up

Thanks,

Yiping

Thank you Yiping.

I noticed you have answered similar question, bridge interface not working on LS1028A RDB 

Which script is more general? And would there be a generic script for this purpose from NXP?

Best,

You also could refer to the section "CPU port with simple bridge configuration and L2 forwarding support" in BSP 0.3 document, the script is provided in this document.

Thanks,

I tried as the section "CPU port with simple bridge configuration and L2 forwarding support" in BSP 0.3. But it fails to successfully ping from swp0 to the remote host (in my case, it is 192.168.10.10). But I can ping from remote host to swp0.

Could you help to check the reason behind?

by printing the ip route table, there is entry exist for "192.168.10.0/24 ...." in the switch net name space.

[root@OpenIL-LS1028ARDB:~]# ip netns exec swns ip route
192.168.10.0/24 dev br0 proto kernel scope link src 192.168.10.100

Thanks,

My script is:
