CoS classifiers - logical interface family

‎07-18-2018 04:21 AM

Most of the Juniper articles clarifies if CoS classifiers should be applied to Logical or Physical interface. For EX and QFX switches the logical interface must be used, mostly unit 0.

What is never mentioned if the logical interface family type matters (ethernet-switching or inte etc) or not. Does it ?

When its family inet we need to use classifier based on DSCP/TOS which is present in IP header. And if we have family ethernet switch, we need to use 802.1p (from L2 header) as in ethernet switching interface cannot read the IP header.
