Hi to all


Yesterday i found on my 9300 output drops, using 

Cisco CLI Analyzer tool, i found that is due to Glean Adjacency 

interface with drops is connected directly to our fw with internet access, 

changed cables and both interfaces have same speed 1Gb

What can i do or check to solve that, i am not an expert on CEF  just know that is used on L3 switchs to forward packets,

there is no problems with stp either


below is the command output


thanks in advance for any help or clue to solve it
