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.
Syntax
match ip tos <tosbits> <tosmask>
<
tosbits>
is a two-digit hexadecimal number from 00 to ff.
<
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).
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.
In essence, this the
“free form” version of the IP DSCP/Precedence/TOS match
specification in that the user has complete control of specifying which bits of the IP Service
Type field are checked.
Default Setting
None
