CLI Command Reference
match ip precedence
This command adds to the specified class definition a match condition based on the value of
the IP Precedence field in a packet, which is defined as the high-order three bits of the Service
Type octet in the IP header (the low-order five bits are not checked). The precedence value is
an integer from 0 to 7.
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 different user notation.
Default none
Format
match 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 ff. The value
of
<tosmask> is a two-digit hexadecimal number from 00 to ff. 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).
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 different 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 ip tos <tosbits> <tosmask>
Mode 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.
To specify the match condition using a numeric value notation, the protocol number is a
standard value assigned by IANA and is interpreted as an integer from 0 to 255.
NOTE: This command does not validate the protocol number value against the cur-
rent list defined by IANA.
