Re: Juniper QFX port VLAN statistics via SNMP - is it possible?

[Stanislaw <me () nek0 net>]

I'll just leave the solution here in case that anybody else needs it:

Firewall rule:
firewall {
    family ethernet-switching {
        filter vlan-counters {
            interface-specific;
            term vlan-14 {
                from {
                    dot1q-tag 14;
                }
                then {
                    accept;
                    count vlan-14;
                }
            }
            term vlan-571 {
                from {
                    dot1q-tag 571;
                }
                then {
                    accept;
                    count vlan-571;
                }
            }
            term vlan-572 {
                from {
                    dot1q-tag 572;
                }
                then {
                    accept;
                    count vlan-572;
                }
            }
            term default {
                then accept;
            }
        }
    }
}

Applying it:
set interfaces ae0.0 family ethernet-switching filter input 
vlan-counters
set interfaces ae0.0 family ethernet-switching filter output 
vlan-counters

Checking the show firewall output:
Filter: vlan-counters-ae1.0-i
Counters:
Name                                                Bytes              
Packets
vlan-14-ae1.0-i                                   7474383                
 8504
vlan-571-ae1.0-i                                        0                
    0
vlan-572-ae1.0-i                                        0                
    0

Filter: vlan-counters-ae1.0-o
Counters:
Name                                                Bytes              
Packets
vlan-14-ae1.0-o                                   2651051                
 4919
vlan-571-ae1.0-o                                  2057853                
14731
vlan-572-ae1.0-o                                      644                
   10

Now, SNMP get:
$ snmpget -v2c -cpublic 10.1.2.3 
'JUNIPER-FIREWALL-MIB::jnxFWCounterByteCount."vlan-counters-ae1.0-o"."vlan-571-ae1.0-o".counter
JUNIPER-FIREWALL-MIB::jnxFWCounterByteCount."vlan-counters-ae1.0-o"."vlan-571-ae1.0-o".counter 
= Counter64: 298848


Thanks Luke Guillory for the solution!
