Default Setting
None
Command Mode
Extended ACL
Command Usage
• All 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.
• You can specify both Precedence and ToS in the same rule. However,
if DSCP is used, then neither Precedence nor ToS can be specified.
1. Includes TCP, UDP or other protocol types.
