Access Control Lists (ACLs)
Configuring ACLs
Note The mark operation only takes effect if you apply this ACL to a physical
interface.
5. Optionally, check the Logging box to allow the module to keep track of
the number of packets matched to this rule.
6. If you selected the mark operation in step 4, under Attribute to mark, select
one of the following:
• 802.1p—Then specify the traffic service class value, from 0 through 7.
• TOS—Then specify the value for the TOS octet, from 0 through 255.
Standard DSCP values are from 0 through 63.
Remember that higher values typically mark traffic for better QoS.
7. Under Filter, use the Protocol drop-down menu to select the protocol:
•icmp
•ip
•tcp
•udp
The ACL rule matches traffic that uses the specified protocol. You can
make the filter more specific than the protocol alone. That is, if you choose
icmp, tcp, or udp, you should specify protocol options that select certain
types of ICMP, TCP, or UDP traffic, based on information in the respective
protocol header. If you select ip, the rule selects any IP packet that
matches other filters, and you cannot specify special protocol options.
8. If you selected icmp, tcp, or udp in step 7, click the Protocol Options button.
a. If you selected the ICMP protocol, the ICMP Options screen is dis-
played. (See step b on page 7-21 if you selected the TCP or UDP
protocol.)
