Hi All. I have an ERX1440 with 4 Gig interfaces, using ECMP. What are the correct commands I can use to determine if load balancing is really happening? I'm already using "show interfaces". I'd like something more advance...

Thank you.

Hi Thiaguets,


If you want to check the ECMP, you could use the next commands:


show ip route (I'm imaging that you have that links to your default router)

show int giga x/y (To check in the part of input and output rates. In all interfaces should be with the same rate)


if you want more information, search into Techpubs (, here there are more information about the JunoSE and example of configurations.


Best regards,

Alternately, if you want to look at the actual egress data rate, you can enable a 'rate' in the default QoS statistics profile as follows:


statistics-profile default

  rate 30


and then use the 'show egress rates interface g1/0', 'show egress rates interface g2/0', etc. to view the real-time egress rates for each IP interface.
