X670 15.3.2.11 stops forwarding random traffic

[Dawid_Chrzan]

Hi,
X670 with XOS 15.3.2.11 - started to act quite weird.
It stopped to forward some packets from some mac addresses.
We use port mirroring - and i heard that sometimes - xos starts to lose random traffic when using old firmware.
We rebooted - and all worked OK.
But today we have similar problem.

We have been sugested to upgrade to 15.6.1.4 or 15.5.3.4 patch1-2. Is it a good idea ?
Any info about stability of these versions?

15.3.4.6-patch1-10 solved the issue

I believe the known issue Parthiban is referring to is PD4-4490184741. This is documented in the EXOS 15.3.1.4-patch1-36 release notes, as this was the first release that included the fix for this issue.

"This is a known issue." - do you have any references for this statement?

Thanks.
I will try 15.3.4.6-patch1-10 that i received.
Is multicast routing (PIM-SM) and VMAN stable in that realease ?
