I have a domain eaps , and i did a test for a frame size 64 bytes , for the primary port the test is sucefull but when did a fail over at  the secondary port  test no pass.

I have configure jumbo frame , can you share the possibilities for this scenery ?

Hello E Fierros,

Can you please elaborate on the test and the process you went through to fail over EAPS?

The situation is when change the path for the secondary port (fail over) the test that ran fail. Exactly with frames 64 bytes - 350 bytes 


I saw a congestion over the neighbors port but for the route primary (a1-jade - d2-ppps-d1-ppps) is the same behavior and the test dont have errors (frames loss)

This is the capture of errors

Did the redundant path take over and your test stopped dropping frames?  There is always some packet loss when you have a link failure and there will be some packet loss when you restore.  I am assuming that this is what you are seeing is a pass or fail from a test set based purly on packet loss and not how long it takes the network to restore when you do the fail over.

Hi Ethernet Man , Thanks for the information  and know maybe exist the posibility  drop paquets when did a fail over. But the situation is that I make or ran a test RFC2544 because I am checking the 2 path ( primary and secondary) like attached topology nothing change on the path only when did a change over the eaps- ́perisur.  For one side the test is exitoso (primary) but for the second path is not working fine and appears lost frames

So with a 3 point ring where are you placing your test set and where is the loopback for your testing ?   This would help you narrow down a problem with one of the links.

Ok the equipment that function like a loopback is connected on port 1 equipment a1-jade and the emisor equipment is connected in another ring .
