Figure 85 A ToS/traffic class field
Syntax:
[no] [seq—number] [ match | ignore ] [icmp] source—address destination—address
[ icmp—type—number | icmpv4—type—name | icmpv6—type—name ] [ ip—dscp
codepoint ] [ precedence precedence—value ] [ tos tos—value ] [ vlan—id ]
If you enter icmp as the IP protocol type in a match/ignore statement, you can
optionally specify an ICMP packet type to more precisely define match criteria for
a traffic class. Enter the optional ICMP match criteria immediately after the
destination address (DA) value in the command syntax; for example:
HP Switch(config-class)#: match icmp any any host-unknown
HP Switch(config-class)#: match icmp any any 3 7
icmp-type-number Configures an ICMP packet type as match criteria in a
class configuration by entering its numeric identifier.
Valid values are from 0 to 255.
For information on ICMP packet-type names and numeric
identifiers, go to the Internet Assigned Numbers Authority
(IANA) website at www.iana.com, click Protocol Number
Assignment Services, and then go to the selections under
Internet Control Message Protocol (ICMP) Parameters.
icmpv4-type-name Enter any of the following ICMPv4 packet-type names to
configure more precise match criteria for ICMP packets
in an IPv4 class configuration.
To display a list of valid icmpv4-type-name entries
when entering icmp as the IP protocol type in a
match/ignore statement, enter ?. Some of the valid values
are:
• administratively-prohibitednet-tos-unreachable
• alternate-addressnet-unreachable
• conversion-errornetwork-unknown
• dod-host-prohibitedno-room-for-option
• dod-net-prohibitedoption-missing
• echopacket-too-big
