9300 sfp port blinking green amber

[adeebtaqui]

Greetings

Kindly guide me to resolve the below issue

Our new 9300-24p deployed as core switch is not able to establish link to new access switch uplink having sfp-10g-sr-s. The uplink port on core switch te1/1/2 led is blinking green amber while the 9200 te1/1/1 is blinking green. 9200 is showing 9300 as cdp neighbor but cannot ping or communicate with 9300 core.

9300 facing no problem with other 9200 access switch

Fiber test shows -3loss for multi mode

Could there be a bug issue in 9200 access switch.

STAT
(port status)

Off

No link, or port was administratively shut down.

Green

Link present.

Blinking green

Activity. Port is sending or receiving data.

Alternating green-amber

Link fault. Error frames can affect connectivity, and errors such as excessive collisions, cyclic redundancy check (CRC) errors, and alignment and jabber errors are monitored for a link-fault indication.

Amber

Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data.

Note After a port is reconfigured, the port LED can remain amber for up to 30 seconds as STP checks the network topology for possible loops.

Blinking amber

Port is blocked by STP and is not sending or receiving packets.

What firmware are both switches running on?
