Example
This example accepts any incoming packets if the source address is within subnet
10.7.1.x. For example, if the rule is matched; i.e., the rule (10.7.1.0 & 255.255.255.0)
equals the masked address (10.7.1.2 & 255.255.255.0), the packet passes through.
Console(config-ext-acl)#permit 10.7.1.1 255.255.255.0 any
Console(config-ext-acl)#
This allows TCP packets from class C addresses 192.168.1.0 to any destination
address when set for destination TCP port 80 (i.e., HTTP).
Console(config-ext-acl)#permit 192.168.1.0 255.255.255.0 any destination-port
80

This permits all TCP packets from class C addresses 192.168.1.0 with the TCP control
code set to "SYN. "
Console(config-ext-acl)#permit tcp 192.168.1.0 255.255.255.0 any control-
