Table 25: IPv6 Classification Fields for a 144-bit CAM Entry

288-bit IPv6 Classification Example

The following example creates and attaches a policy, which requests classification
on a single host address and TCP. The configuration exceeds the 128 bit limit.

Variable-Sized CAM Classification for IPv6 Policies Examples
Match all ICMPv6 echo packets.
host1(config)#ipv6 classifier-list icmpv6CLACL icmpv6 icmp-type 8 icmp-code
0
Match all frames with the color red.
host1(config)#ipv6 classifier-list colorCLACL color red
Create an IPv6 policy list.
host1(config)#ipv6 policy-list ipv6Pol

The policy ipv6Pol is requesting classification on Source Address (first word),
Destination Address (first word), Destination Port, Protocol, TCP Flags, ICMPv6
Type, ICMPv6 Code, Color, and TC field. Table 25 on page 172 lists the active
classifiers in the policy named ipv6Pol and the size of each classifier.
Classifiers
Source address (first word)
Destination address (first word)
Destination port, ICMPv6 type, ICMPv6
code
Protocol
Color and TCP flags
TC field
The sum of all classification fields requested in ipv6Pol is 104. This size causes
Policy Manager to use 144-bit CAM entry for every classifier in this policy. One
CAM entry is needed for each classifier in the policy and therefore, four 144-bit
CAM entries are needed in all.
