8-12
Classifier-Based Software Configuration
Traffic Classes
Valid values are the numeric value or corresponding
name of the DTR bit set. Some useful values are as
follows:
0normal
2 max-reliability
4 max-throughput
8 minimize-delay
Default: 0 or normal.
To display a list of valid tos-value entries when you
enter tos in a match/ignore statement, type ?.
Notes: When used as a match criteria, the ToS/
Traffic Class byte entry is applied in addition to
all
other criteria configured in the match/ignore state-
ment. You can enter a match/ignore statement either
with or without a tos-value.
Figure 8-2 shows the DTR bit set in a ToS/Traffic
Class byte in an IPv4/IPv6 packet header and the
difference between the DSCP, DTR, and precedence
bits.
[ vlan vlan-id ]
(Optional) Matches the VLAN ID number in the
Layer 2 header of 802.1Q VLAN packets to further
define match criteria. Valid VLAN IDs are from 1 to
4094.
