Yes in this case configuration it is very similar, i put it:

SWL3(config)#access-list 101 permit ip 1.1.1.1 0.0.0.2 10.1.1.0 0.0.0.255
SWL3(config)#access-list 101 permit ip host 1.1.1.2 10.1.1.0 0.0.0.255 
SWL3(config)#access-list 101 deny ip 1.1.1.0 0.0.0.255 10.1.1.0 0.0.0.255
SWL3(config)#access-list 101 permit ip any any

SWL3(config)int vlan 20
SWL3(config-if)ip access-group 101 out
