A source or destination class is applied to a packet only once during the
routing table lookup. When a network prefix matches a class-usage policy,
SCU is assigned to packets first; DCU is assigned only if SCU has not been
assigned. Be careful when using both class types, since misconfiguration can
result in uncounted packets.

Subject: [j-nsp] Destination Class Accounting: counters are zero
Hello List,
I have MX240 router (10.0 R4.7) with two peering links and two upstream
links.
I need separate accounting of customer's traffic: to/from upstreams and
to/from peerings.
I configured an SCU input accounting on peering and upstream links,
DCU and SCU output accounting on customer's link:
minot...@br1-gdr.ki# show interfaces ae0 unit 753
vlan-id 753;
family inet {
accounting {
source-class-usage {
output;
}
destination-class-usage;
}
no-redirects;
filter {
output bw-100M-U;
}
address 109.68.41.133/30;
}
Then I applied export policy to forwarding table, now every route
has an assigned class, for example:
minot...@br1-gdr.ki# run show route juniper.net table Salt extensive |
match class
Destination class: to-Upstream
Source class: from-Upstream
Now let's check extensive information about customer's interface:
minot...@br1-gdr.ki# run show interfaces ae0.753 extensive
Logical interface ae0.753 (Index 97) (SNMP ifIndex 197) (Generation 168)

Why 'to-Upstream' counters are zeroes?
Thanks in advance!
