The best way is using vlan access-map.
we want to filter ping packet from R1 - SW1 - R2 in vlan 25
SW1
ip access-list extended ICMP
permit icmp any any
vlan access-map block-icmp 10
match ip address ICMP
action drop
vlan access-map 20
action forward
Then apply this policy to selected vlan 25 using this command :
vlan filter block-icmp vlan-list 25
