This shows how to create a standard ACL with an ingress mask to deny access to the IP host
171.69.198.102, and permit access to any others.
Console(config)#access-list ip standard A2
Console(config-std-acl)#permit any
Console(config-std-acl)#deny host 171.69.198.102
Console(config-std-acl)#end
Console#show access-list
IP standard access-list A2:
deny host 171.69.198.102
permit any
Console#configure
Console(config)#access-list ip mask-precedence in
Console(config-ip-mask-acl)#mask host any
Console(config-ip-mask-acl)#exit
Console(config)#interface ethernet 1/1
Console(config-if)#ip access-group A2 in
Console(config-if)#end
Console#show access-list
IP standard access-list A2:
deny host 171.69.198.102
permit any

This shows how to create an extended ACL with an egress mask to drop packets leaving network
171.69.198.0 when the Layer 4 source port is 23.
Console(config)#access-list ip extended A3
Console(config-ext-acl)#deny host 171.69.198.5 any
Console(config-ext-acl)#deny 171.69.198.0 255.255.255.0 any source-port 23
Console(config-ext-acl)#end
Console#show access-list
IP extended access-list A3:
deny host 171.69.198.5 any
deny 171.69.198.0 255.255.255.0 any source-port 23
Console#config
Console(config)#access-list ip mask-precedence out
Console(config-ip-mask-acl)#mask 255.255.255.0 any source-port
Console(config-ip-mask-acl)#exit
Console(config)#interface ethernet 1/15
Console(config-if)#ip access-group A3 out
Console(config-if)#end
Console#show access-list
IP extended access-list A3:
deny 171.69.198.0 255.255.255.0 any source-port 23
deny host 171.69.198.5 any
IP egress mask ACL:
mask 255.255.255.0 any source-port

This is a more comprehensive example. It denies any TCP packets in which the SYN bit is ON, and permits
all other packets. It then sets the ingress mask to check the deny rule first, and finally binds port 1 to this
ACL. Note that once the ACL is bound to an interface (For example, the ACL is active), the order in which
the rules are displayed is determined by the associated mask.
