Problems with port Sharings X670

[Julian_Eble]

Hello,

There's something odd happenings here, and more than that was the solution of it.

We've a sharing with a Juniper MX80, and there're two 10G ports connect on, the 47 and 48 (Extreme).
After issuing the command:

configure sharing 47 add ports 45,46

The hashings seens to not work properly.
The traffic droped significantly, the two added ports (45,46) seems to be more affected than the 47,48.

Then comes the odd "solution", after disabling the sharing and adding again with the master becoming port 45, the problem was solved.

It's a problem to be checked, because it's the second time that I'm having the same problem.
I'm using the version 15.6.3.1 v1563b1-patch1-5.
X670.

Hi,

you mean traffic from X670 to MX80 OR from MX80 to X670 ?
What hash algo. do you use ?

No infos.
Yes, I did check that, but nothing incremented.
I don't have the problem now, because after re-creating the lag it stoped.
No, I haven't see CPU usage.

Any info in logs on X670 ?
Did you check congestion counter on ports?
What shows: debug hal show congestion (hit a few times)

Did you check CPU utilization on X670 after you add a port to the LAG?

Hello Jarek,
Yes, we sent the ping to directly to customers.
No High cpu was found on Juniper.

Thats right, when add the ports 45 and 46 I see the packet loss.
Yes I tried all of them, even fixed and customs.

You send ping to Juniper interface ?
If yes, have you try to ping something that is after the Juniper ?
Maybe cpu on Juniper is busy...

If I understand correctly, you have two port in LAG 47 and 48. 47 is master port.
When you add 45 and 46 to this LAG, you see problems with traffic.
Do you change the hash algorithm ?
Do you use L3_L4 hash or custom hash ?I ask because bellow you have pasted show's with two of them.
