Hi Everyone,
I need your support to find the root cause & resolve this issue, as recently we have connected 8 bare metal server to our ACI network, we start to receive the following logs coming from LF223.
Log from LF223:
10/22/2019 8:38:14 AM 172.16.59.18 Alert LF223-BDC-03-03 %LOG_-4-SYSTEM_MSG [E4209105][config-mismatch][warning][sys/lldp/inst/if-[eth1/25]/adj-1] LLDP neighbor port vlan information is missing
10/22/2019 8:38:11 AM 172.16.59.18 Alert LF223-BDC-03-03 %LOG_-3-SYSTEM_MSG [E4209331][config-mismatch][major][sys/lldp/inst/if-[eth1/22]/adj-1] LLDP neighbor is bridge and its port vlan information is missing. If neighbor is running MST(802.1s) protocol, this could result in a layer2 topology with a loop
10/22/2019 8:38:11 AM 172.16.59.18 Alert LF223-BDC-03-03 %LOG_-3-SYSTEM_MSG [
Also, the system description & LLDP Neighbor port Description keep changing every second, kindly find the following error:
- Broadcom Adv. Dual 25Gb Ethernet fw_version:AFW_20.8.100.0 / LLDP Neighbor port Description (NIC 1/10/25Gb)
- SUSE Linux Enterprise Server 12 SP3 Linux 4.4.162-94.72-default #1 SMP Mon Nov 12 18:57:45 UTC 2018 (9de753f) x86_64/ LLDP Neighbor port Description (slave-0)
Bare Metal Team done troubleshooting the issue and provide the following command but doesn't seems enough information to agree/disagree if the bare metal has been configured correctly.
Quote from VENDOR E-mail:
After consulting with colleagues all three warnings are false lldp interpretations and hence false warnings from your switch.
Those are nodes running suse and not acting as bridges, especially that we don’t have network separation configured on this cluster.
So there are no vlans configured on those interfaces slave-0 and slave-1. They are just bonded as public interface.
Below is an example of the config from node 3:
