Class Map
Cisco WAP131 and WAP351 Administration Guide
• Class Map Name—Choose the IPv4 class map from the list.
• Match Every Packet—The match condition is true to all parameters in a
Layer 3 packet. When enabled, all Layer 3 packets will match the condition.
• Protocol—Uses 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. Choose the protocol to match by keyword or enter a protocol ID:
- Select From List—Matches the selected protocol: IP, ICMP, IGMP, TCP,
UDP.
- Match to Value—Matches 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—Requires a packet's source IPv4 address to match the IPv4
address defined in the appropriate fields.
- Source IP Address—Enter the IPv4 address to apply this criteria.
- Source IP Mask—Enter the source IPv4 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 Port—Includes a source port in the match condition for the rule. The
source port is identified in the datagram header.
- Select From List—Matches a keyword associated with the source port:
ftp, ftpdata, http, smtp, snmp, telnet, tftp, www. Each of these keywords
translates into its equivalent port number.
- Match to Port—Matches the source port number in the datagram header
to an IANA port number that you specify. The port range is from 0 to
65535 and includes three different types of ports:
0 to 1023—Well-Known Ports
1024 to 49151—Registered Ports
