    Posted Sep 08, 2021 08:05 AM

    CG-DL-1-HSWD-1 is the layer 3 switch( 2930F-48G-4SFP+)
    CG-DL-1-HSWB-30 is the layer 2 switch(Aruba 2530 8 Switch )

    CG-DL-1-HSWB-30's port 25 --->connects to CG-DL-1-HSWD-1's 1/30

    Both the ports are tunk.

    We are observing Discard Rx on the port 25 of CG-DL-1-HSWB-30.Can anyone help me to investigate on this.

    CG-DL-1-HSWB-30# sh int 25

    Hello,

     

    What is the running software version in the device?

     

    Have you tried to replace or swap the tranceiver?

     

    Is Jumbo frame enabled?

     

     

    Thanks!
