the specified source. Use the no form to remove a rule.

source
Source IP address.
bitmask
Decimal number representing the address bits to match.
host
Keyword followed by a specific IP address.
Default
None
Command Mode
Standard ACL
Usage Guidelines
New rules are appended to the end of the list.
Address bitmasks are similar to a subnet mask, containing four integers from 0 to 255, each separated by a
period. The binary mask uses 1 bits to indicate “match” and 0 bits to indicate “ignore.” The bitmask is bitwise
ANDed with the specified source IP address, and then compared with the address for each IP packet
entering the port(s) to which this ACL has been assigned.
Example
This example configures one permit rule for the specific address 10.1.1.21 and another rule for the address
range 168.92.16.x – 168.92.31.x using a bitmask.
Console(config-std-acl)#
permit host 10.1.1.21
Console(config-std-acl)#
permit 168.92.16.0 255.255.240.0
Console(config-std-acl)#
