This article explains how to obtain statistics for the logical child links of an aggregated interface.
By default, users cannot see the statistics for the logical child links of an aggregated interface. Statistics output on one direction or duplicated stats may be seen.
Topology:
QFX10K -- ae0 -- QFX5K
Configuration:
{master:0}[edit] root@switch# show interfaces ae0 unit 0 { family ethernet-switching { vlan { members v100; } } } {master:0}[edit] root@switch# show interfaces irb unit 100 { family inet { address 1.1.1.100/24; } }
AE0 interface details:
{master:0}[edit] root@switch# run show interfaces terse | match ae0 et-0/0/30.0 up up aenet --> ae0.0 et-0/0/31.0 up up aenet --> ae0.0 ae0 up up ae0.0 up up eth-switch
Verification using ICMP packet:
{master:0}[edit] root@switch# run ping 1.1.1.100 rapid count 1000 PING 1.1.1.100 (1.1.1.100): 56 data bytes !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! --- 1.1.1.100 ping statistics --- 1000 packets transmitted, 1000 packets received, 0% packet loss round-trip min/avg/max/stddev = 1.492/2.214/61.505/3.239 ms
Packets are seen only on output direction in et-0/0/30:

Use the 'fpc-ifl-ae-statistics' knob to populate the statistics correctly. In this example, statistics populated correctly in both input and output direction.
'fpc-ifl-ae-statistics'
{master:0}[edit] root@switch# show chassis aggregated-devices { ethernet { device-count 3; } } fpc 0 { pic 0 { port 0 { channel-speed 10g; } } } fpc-ifl-ae-statistics;
The correct input/output statistics are seen in the child interface(et-0/0/30) of the ae0:
