Im getting discards on a clients 4500 l3 switch.
The interface is gigabit set to 1000mpbs full duplux on both sides of the link.
The other end is a sonicwall firewall also gigabit.
Here is the output of some of my commands
LVCC4507#show int gi3/16
GigabitEthernet3/16 is up, line protocol is up (connected)

Any help troubleshooting would be great.
