• host – Keyword followed by a specific IP address.
• precedence – IP precedence level. (Range: 0-7)

• dscp – DSCP priority level. (Range: 0-64)
• sport – Protocol* source port number. (Range: 0-65535)
• dport – Protocol* destination port number. (Range: 0-65535)
• port-bitmask – Decimal number representing the port bits to match.
(Range: 0-65535)
• control-flags – Decimal number (representing a bit string) that specifies
flag bits in byte 14 of the TCP header. (Range: 0-63)

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.
• The control-code bitmask is a decimal number (representing an
equivalent bit mask) that is applied to the control code. Enter a decimal
number, where the equivalent binary bit “1” means to match a bit and
“0” means to ignore a bit. The following bits may be specified:
