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.
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.
