16 ! Creating Classifier Control Lists

! Use the protocol option to match a specific protocol number and specify

protocol attributes:

! icmpv6—ICMP type and code

! tcp—TCP protocol attributes, such as source and destination port, and

source and destination TCP operator and port

! udp—UDP protocol attributes, such as source and destination port

! For TCP and UDP, use the portQualifier option to specify a single port or a range

of source or destination ports. The portQualifier option is composed of:

! portNumber—Single port number or the beginning of a range of port

numbers

! toPortNumber—End of a range of port numbers

! portOperator—One of the following:

" eq—equal to

" lt—less than

" gt—greater than

" neq—not equal to

" range—range of ports

For example, the following command matches packets from port 75:

host1(config)#ipv6 classifier-list YourListName udp destination-port eq 75

! For TCP, use the tcp-flags keyword and a logical equation (a quotation-enclosed

string using ! for NOT, & for AND) to match one or more of the following TCP

flags: ack, fin, psh, rst, syn, urg. For example:

host1(config)#ipv6 classifier-list telnetConnects tcp destination-port eq 23

tcp-flags "syn & !ack"

! For ICMPv6, use the icmp-type option to specify the icmpType and icmpCode

parameters:

! icmpType—ICMP message type; in the range 0–255

! icmpCode—ICMP message code; in the range 0–255

For example, the following command matches ICMPv6 packets with an ICMP

type of 3 and code of 6:

host1(config)#ipv6 classifier-list listname icmpv6 icmp-type 3 icmp-code 6

! Use the following keywords to configure classification to match route-class

values:

! source-route-class—Classifies on packets associated with a route class

based on the packet’s source address; route-class range is 0–255; default is

! destination-route-class—Classifies on incoming packets associated with a

route class based on the packet’s destination address; route-class range is

0–255; default is 0.
