The match criteria fields that are available depend on whether the class map is an IPv4 or IPv6
class map.
Defining a Class Map
To configure a class map:
STEP 1
Select the class map from the Class Map Name list.
STEP 2
Configure the parameters (parameters that appear only for IPv4 or IPv6 class maps are noted):
•
Match Every Packet—The match condition is true to all the parameters in a Layer 3
packet.
When selected, all Layer 3 packets will match the condition.
•
Protocol—Use a Layer 3 or Layer 4 protocol match condition based on the value of the
IP Protocol field in IPv4 packets or the Next Header field in IPv6 packets.
If you select this field, choose the protocol to match by keyword or enter a protocol ID.
-
Select From List—Match the selected protocol: IP, ICMP, IPv6, ICMPv6, IGMP,
TCP, UDP.
-
Match to Value—Match a protocol that is not listed by name. Enter the protocol ID.
The protocol ID is a standard value assigned by IANA. The range is a number from
0 to 255.
•
Source IP Address or Source IPv6 Address—Requires a packet's source IP address to
match the address listed here. Check the box and enter an IP address.
•
Source IP Mask (IPv4 only)—The source IP address mask.
The mask for DiffServ is a network-style bit mask in IP dotted decimal format
indicating which part(s) of the destination IP address to use for matching against packet
content.
A DiffServ mask of 255.255.255.255 indicates that all bits are important, and a mask of
0.0.0.0 indicates that no bits are important. The opposite is true with an ACL wildcard
mask. For example, to match the criteria to a single host address, use a mask of
255.255.255.255. To match the criteria to a 24-bit subnet (for example, 192.168.10.0/
24), use a mask of 255.255.255.0.
•
Source IPv6 Prefix Length (IPv6 only)—The prefix length of the source IPv6 address.
•
Destination IP Address or Destination IPv6 Address—Requires a packet's destination
IP address to match the address listed here. Enter an IP address in the appropriate field
to apply this criteria.
