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.

15. Includes TCP, UDP or other protocol types.
