Default Behavior Aggregate Classification
Juniper Networks Junos OS automatically assigns implicit default classifiers to all logical
interfaces based on the type of interface. Table 403 on page 3154 lists different types of
interfaces and the corresponding implicit default classifiers.
Table 403: Default BA Classification
Default BA Classification
Type of Interface
ieee8021p-default
Trunk interface
dscp-default
Layer 3 interface (IPv4)
dscp-ipv6-default
Layer 3 interface (IPv6)
Untrusted
Access interface
No default classification
Routed VLAN interface (RVI)
When you explicitly associate a classifier with a logical interface, you are in effect
overriding the implicit default classifier with an explicit classifier.
On EX3200 and EX4200 switches, you can apply classifier rules for each interface. Table
404 on page 3154 describes the different classifier types you can configure on Layer 2 and
Layer 3 interfaces.
Table 404: Allowed BA Classification
Allowed BA Classification
Type of Interface
IEEE 802.1p, IP Precedence, DSCP, DSCP IPv6
Layer 2 interface
IEEE 802.1p, IP Precedence, DSCP
Layer 3 interface (IPv4)
IEEE 802.1p, IP Precedence, DSCP IPv6
Layer 3 interface (IPv6)
You can configure all the allowed classifier types on the same logical interface or on
different logical interfaces. If you need to apply all classifier rules on the same logical
interface, configure the classifier rules allowed for both IPv4 and IPv6 on the logical
interface.
If you have not explicitly associated a classifier with a logical interface, the default
classifiers are assigned and classification works as follows:
•
If the logical interface is configured with an IPv4 address, DSCP classifier is assigned
by default, and IPv4 and IPv6 packets are classified using the DSCP classifier.
•
If the logical interface is configured with an IPv6 address, DSCP IPv6 classifier is
assigned by default, and IPv4 and IPv6 packets are classified using the DSCP IPv6
classifier.
