Chapter 3 CLI Commands
To create an entry, use a deny or permit keyword and specify the type of packets that you want the
WAAS device to drop or to accept for further processing. By default, an access list denies everything
because the list is terminated by an implicit deny any entry. Therefore, you must include at least one
permit entry to create a valid access list.
After creating an access list, you can include the access list in an access group using the access-group
command, which determines how the access list is applied. You can also apply the access list to a specific
application using the appropriate command. A reference to an access list that does not exist is the
equivalent of a permit any condition statement.
To create a standard access list, enter the ip access-list standard global configuration command.
Identify the new or existing access list with a name up to 30 characters long beginning with a letter, or
with a number. If you use a number to identify a standard access list, it must be between 1 and 99.
Note You must use a standard access list for providing access to the SNMP server or to the TFTP
gateway/server. However, you can use either a standard access list or an extended access list for
providing access to the WCCP application.
You typically use a standard access list to allow connections from a host with a specific IP address or
from hosts on a specific network. To allow connections from a specific host, use the permit host
source-ip option and replace source-ip with the IP address of the specific host.
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.
After you identify the standard access list, the CLI enters the standard ACL configuration mode and all
subsequent commands apply to the specified access list.
WAE(config)# ip access-list standard teststdacl
WAE(config-std-nacl)# exit
Examples The following example creates a standard access list on the WAAS device that permits any packets from
source IP address 192.168.1.0 for further processing:
WAE(config)# ip access-list standard teststdacl
WAE(config-std-nacl)# permit 192.168.1.0 any
WAE(config-std-nacl)# exit
The following commands activate the 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
