Switch Setup on LS1028ARDB

zing — Wed, 03 Jun 2020 11:31:53 GMT

I try to get the interfaces swp0-swp3 to run. I use the following software

root@LS1028ARDB-Ubuntu:~# uname -a
Linux LS1028ARDB-Ubuntu 5.4.3-rt1 #1 SMP PREEMPT_RT Wed May 27 07:13:13 CEST 2020 aarch64 aarch64 aarch64 GNU/Linux

The following release was used to build the os:

OpenIL-v1.8-202005

I try to setup the switch interfaces as described in LSDKUG_Rev19.09 Figure 211. The output of the given script is:

setup_bridge.sh setup_eno0.sh setup_switch.sh
root@LS1028ARDB-Ubuntu:~# ./setup_switch.sh
RTNETLINK answers: Network is down
RTNETLINK answers: Network is down
RTNETLINK answers: Network is down
RTNETLINK answers: Network is down
ls: cannot access '/sys/bus/pci/devices/0000:00:00.6/net/': No such file or directory
Not enough information: "dev" argument is required.

Also i can not bring the interfaces up manually (eno0 works fine dhc and everything works!)

I suspect a driver problem, however it seem the felix driver is there:

Any Ideas how to bring up the switch interfaces?

Thanks for your response and adjusted script! Interfaces are now up and I can use them.

Hello zing@zhaw.ch,

I am facing a similar issue. Can you please share setup_bridge.sh, setup_eno0.sh and setup_switch.sh files?

Regards,

Sameer

Hi Sir, I am using LS1028A board,

how can I print the debug message as follows when using 'ifconfig' :

root@ls1028ardb:~# ifconfig swp0 100.1.1.29 netmask 255.255.255.0
[ 90.042476] mscc_felix 0000:00:00.5 swp0: configuring for inband/qsgmii link mode
[ 90.050569] 8021q: adding VLAN 0 to HW filter on device swp0

I am trying to set up ethernet interface on LS1028ARDB as well. I run your shell script to bring the interfaces up, then follow the next steps. I do see the lines:

mscc_felix 0000:00:00.5 swp0: Link is Up -- 1Gbps/Full - flow control rx/tx

IPv6: ADDRCONF(NETDEV_CHANGE): swp0: link becomes ready

However, when I try ping -c 5 -s 1 100.1.1.1, the ping fails and I get Destination Host Unreachable.

my output of `ip a` shows:

eno2: <BROADCAST,MULTICAST,UP,LOWER_UP> with no ip address, and

swp0@eno2: <BROADCAST,MULTICAST,UP,LOWER_UP> with ip address 100.1.1.29

Any ideas?
