Add rules to the ACL.
acl-id-or-name
: Enter the ID or name of the ACL that you want to add a rule for.
auto:
The rule ID will be assigned automatically and the interval between rule IDs is 5.
rule-id
: Assign an ID to the rule.
deny | permit
: Specify the action to be taken with the packets that match the rule. Deny means
to discard; permit means to forward. By default, it is set to permit.
logging
{enable | disable}
: Enable or disable Logging function for the ACL rule. If "enable" is
selected, the times that the rule is matched will be logged every 5 minutes. With ACL Counter
trap enabled, a related trap will be generated if the matching times changes.
sip-address:
Enter the source IP address.
sip-address-mask:
Enter the mask of the source IP address. This is required if a source IP
address is entered.
dip-address:
Enter the destination IP address.
dip-address-mask:
Enter the mask of the destination IP address. This is required if a
destination IP address is entered.
dscp-value:
Specify the DSCP value between 0 and 63.
tos-value:
Specify an IP ToS value to be matched between 0 and 15.
pre-value:
Specify an IP Precedence value to be matched between 0 and 7.
protocol:
Specify a protocol number between 0 and 255.
s-port-number:
With TCP or UDP configured as the protocol, specify the source port number.
s-port-mask:
With TCP or UDP configured as the protocol, specify the source port mask with 4
hexadacimal numbers.
d-port-number:
With TCP or UDP configured as the protocol, specify the destination port
number.
d-port-mask:
With TCP or UDP configured as the protocol, specify the destination port mask
with 4 hexadacimal numbers.
tcpflag:
With TCP configured as the protocol, specify the flag value using either binary
numbers or * (for example, 01*010*). The default is *, which indicates that the flag will not be
matched.
The flags are URG (Urgent flag), ACK (Acknowledge Flag), PSH (Push Flag), RST (Reset Flag),
SYN (Synchronize Flag) and FIN (Finish Flag).
time-range-name:
The name of the time-range. The default is No Limit.
