Default None
Format match [not] ip precedence 0-7
Mode Class-Map Config
match ip tos
This command adds to the specified class definition a match condition based on the value of the IP TOS
field in a packet, which is defined as all eight bits of the Service Type octet in the IP header. The value of
tosbits is a two-digit hexadecimal number from 00 to . The value of tosmask is a two-digit
hexadecimal number from 00 to . The tosmask denotes the bit positions in tosbits that are used for
comparison against the IP TOS field in a packet. For example, to check for an IP TOS value having bits 7
and 5 set and bit 1 clear, where bit 7 is most significant, use a tosbits value of a0 (hex) and a tosmask of
a2 (hex). Use the [not] option to negate the match condition.
Note
The IP DSCP, IP Precedence, and IP ToS match conditions are alternative ways to specify a
match criterion for the same Service Type field in the IP header, but with a slightly dierent
user notation.
Note
This “free form” version of the IP DSCP/Precedence/TOS match specification gives the user
complete control when specifying which bits of the IP Service Type field are checked.
Default None
Format match [not] ip tos tosbits tosmask
Mode Class-Map Config
match ip6flowlbl
Use this command to enter an IPv6 flow label value. Use the [not] option to negate the match condition.
Default
None
Format match [not] ip6flowlbl label 0-1048575
Mode IPv6-Class-Map Config
match protocol
This command adds to the specified class definition a match condition based on the value of the IP
Protocol field in a packet using a single keyword notation or a numeric value notation.
To specify the match condition using a single keyword notation, the value for protocol-name is one of
the supported protocol name keywords. The currently supported values are: icmp, igmp, ip, tcp, udp. A
value of ip matches all protocol number values.
