I see there is setting in switch
By switch, I assume you mean layer 3 switch or router.
why disable?
no ip directed-broadcast
"no ip directed-broadcast" is generally a good thing. It blosks smurf
DoS attacks.
no ip route-cache
This is generally NOT a good thing, other than for debugging during
low-traffic scenarios. It forces traffic to be process-switched and
will cause high (or very high) router CPU utilization.
