Chapter 25 Configuring Quality of Service
Configuring Quality of Service
– Ingress VLAN classification is not supported on switchport interfaces configured as dot1q
tunnels using the switchport mode dot1q-tunnel command. We recommend that you configure
classification based on CoS, Exp bit, or DSCP.
• The following limitations apply to output Gigabit Ethernet interface QoS policies:
– Class maps only support matching based on qos-group. This limitation does not apply to the
class-default class map.
– You cannot create two policy maps that match based on the same qos-group value.
• The following limitations apply to input MLPPP interfaces:
– You can create up to 8 matches in a class-map using DSCP or MPLS Exp values.
Marking Limitations
Table 25-2 summarizes the values that you can use to mark traffic based on interface type. The values
are parameters that you can use with the set command.
