Before the issue happened，we warm-reboot the device，but there is no error in syslog.

Maybe something wrong in kernerl，we do action: 1.ifconfig Ethernet11 down 2.ifconfig Ethernet11 up

The problem disappears. show lldp neighbors Ethernet11

@coolkidBigEye could you attach the tech support?

@coolkidBigEye could you check if this fix is included https://github.com/sonic-net/sonic-buildimage/pull/9519 and if lldp restart helps?

I know this issue and the problem is found after this issue fixed。

The problem occurred only once, and there was no tech surport at that time. The problem will continue to be reproduced locally.
