LLDP support in LS1028ARDB

sameer_chouksey — Tue, 30 Jun 2020 10:12:28 GMT

Hello people,

I am trying to integrate the LS1028 board in a bigger network where I need LLDP service discovery protocol to be running the board. Does the LS1028 supports LLDP? Do we have some libraries available to enable it??

Thanks & Regards,

Sameer

The group in charge of LS1028A software doesn't do any LLDP specific testing.

That being said, there are no known problems surrounding it, since there is no special platform-level support required for LLDP.

In OpenIL 1.8, one can enable BR2_PACKAGE_LLDPD. For testing, the resulting rootfs can be deployed on 2 LS1028A-RDB boards, and a cable connecting eno0 to swp0 can be added.

The lldpd daemon is started automatically by /etc/init.d/S60lldpd. So, the lldpcli can be used directly:

Board 1:

[lldpcli] # show neighbors

-------------------------------------------------------------------------------

LLDP neighbors:

-------------------------------------------------------------------------------

Interface: swp0, via: LLDP, RID: 1, Time: 0 day, 00:00:14

Chassis:

ChassisID: mac 00:04:9f:05:f4:ab

SysName: LS1028ARDB

SysDescr: Buildroot 2020.02 Linux 5.4.3-rt1 #1 SMP PREEMPT_RT Thu Jun 18 20:20:05 EEST 2020 aarch64

-------------------------------------------------------------------------------

Board 2:

[lldpcli] # show neighbors

-------------------------------------------------------------------------------

LLDP neighbors:

-------------------------------------------------------------------------------

Interface: eno0, via: LLDP, RID: 1, Time: 0 day, 00:00:06

Chassis:

ChassisID: mac 00:04:9f:05:de:06

SysName: LS1028ARDB

SysDescr: Buildroot 2020.02 Linux 5.4.3-rt1 #1 SMP PREEMPT_RT Thu Jun 18 20:20:05 EEST 2020 aarch64

MgmtIP: 10.0.0.112

MgmtIP: fdc4:515b:d932:0:7c7c:df93:5af5:b85

Capability: Bridge, off

Capability: Router, off

Port:

PortID: mac 00:04:9f:05:de:0a

PortDescr: swp0

TTL: 120

-------------------------------------------------------------------------------

So the 2 boards see each other.

It is not mandatory to use lldpd, this is just an example.

Hi,Yiping

As you mentioned, "The lldpd daemon is started automatically by /etc/init.d/S60lldpd."

But i can't find S60lldpd in etc filefolder when trying to do LLDP.

Thanks for the responses.

The LLDP package can be added using the menuconfig while building the OpenIL. After rebuilding the OpenIL with LLDP, it is working fine for me.
