Dear Cisco experts.

I am implementing new company strategy and change any catalyst switches with brand new SG500 48 or 24 ports. After change i found that all switches flapping end ports Up and down. Did You have any issue with this. Upgrades firmware to the latest ver and problem still ocure. Port are configured with portfast enabled.

Hi,

If all ports are flapping the switch probably has a hardware issue. I suggest you open a TAC case with Cisco and RMA it.
