Chapter 3 CLI Commands
(config-std-nacl) deny
To allow connections from a specific network, use the permit host source-ip wildcard option. Replace
source-ip with a network ID or the IP address of any host on the network that you want to specify.
Replace wildcard with the dotted decimal notation for a mask that is the reverse of a subnet mask, where
a 0 indicates a position that must be matched and a 1 indicates a position that does not matter. For
instance, the wildcard 0.0.0.255 causes the last eight bits in the source IP address to be ignored.
Therefore, the permit 192.168.1.0 0.0.0.255 entry allows access from any host on the 192.168.1.0
network.
Examples The following example creates standard access-list that denies any packets from source IP address
192.168.1.0 for processing:
WAE(config)# ip access-list standard teststdacl
WAE(config-std-nacl)# deny 192.168.1.0 any
WAE(config-std-nacl)# exit
The following commands activate the standard access list for an interface:
WAE(config)# interface gigabitethernet 1/0
WAE(config-if)# ip access-group teststdacl in
WAE(config-if)# exit
The following example shows how this configuration appears when you enter the show
running-configuration command:
...
!
interface GigabitEthernet 1/0
ip address 10.1.1.50 255.255.0.0
ip access-group teststdacl in
exit
. . .
ip access-list standard example
deny 192.168.1.0 any
exit
