Configuring ACL ACL Configuration
Follow these steps to configure the Packet Content ACL rule:
1) In the Packet Content Rule section, configure the following parameters:
Rule ID Enter an ID number to identify the rule.
It should not be the same as any current rule ID in the same ACL. If you
select Auto Assign, the rule ID will be assigned automatically and the interval
between rule IDs is 5.
Operation Select an action to be taken when a packet matches the rule.
Permit: To forward the matched packets.
Deny: To discard the matched packets.
Chunk0-Chunk3 Specify the EtherType to be matched using 4 hexadecimal numbers.
Chunk Value Enter the 4-byte value in hexadecimal for the desired chunk, like ‘0000ffff’.
The Packet Content ACL will check this chunk of packets to examine if the
packets match the rule or not.
Chunk Mask Enter the 4-byte mask in hexadecimal for the desired chunk. The mask must
be written completely in 4-byte hex mode, like ‘0000ffff’. The mask specifies
which bits to match the rule.
Time Range Select a time range during which the rule will take effect. The default
value is No Limit, which means the rule is always in effect. The Time Range
referenced here can be created on the SYSTEM > Time Range page.
Logging Enable Logging function for the ACL rule. Then the times that the rule is
matched will be logged every 5 minutes and a related trap will be generated.
You can refer to Total Matched Counter in the ACL Rules Table to view the
matching times.
2) In the Policy section, enable or disable the Mirroring feature for the matched packets.
With this option enabled, choose a destination port to which the packets will be
mirrored.
Figure 2-29 Configuring Mirroring
3) In the Policy section, enable or disable the Redirect feature for the matched packets.
With this option enabled, choose a destination port to which the packets will be
redirected.
