Flapping Interfaces on ICX 7150

[Darkmoon_430]

 

Hi community,

I’m reaching out to see if anyone has experienced a similar issue.

We’re seeing random interface flapping on multiple ICX 7150 switches, all running the same firmware version. The affected ports are connected to PoE IP cameras (same model and vendor across all switches and ports).

Environment:

Firmware version: SPR08095k

• Connected devices: IP cameras (same model across all ports)

• Interface config: stp-bpdu-guard
  
  Observations:

• PoE is stable (no faults, normal power draw)

• TDR results also look normal

• STP logs show flapping behavior, transitioning between FORWARDING → BLOCKING → DISABLED (PortDown), then back to FORWARDING

• The issue occurs intermittently and affects different ports

• Other ports with the same camera and cabling work fine
  
  Workarounds Tried:

• Shutting/no shutting the port temporarily resolves the issue

• Moving the camera to another port also works, but the issue may return later
  
  Has anyone else experienced similar interface flapping issues on ICX 7150 switches with IP cameras connected?
  
  Any feedback or suggestions would be greatly appreciated.
  Thanks in advance for your time and support!
