LAG between CSS610 and CSS326

Mon Apr 26, 2021 2:51 pm

Hi Guys,

First post on this forum, so bear with me.

I'm trying to set up a LAG between a CSS610 and CSS326. However there are some troubling issues going on.
I'm setting u between two gigE ports, but it looks like the C610 is not liking this at all. As soon the second link is up (a group of 2 links), LAG is up and i see traffic on both interfaces, on both switches. but is preforms poorly and sometimes loses all connection.

RSTP is also showing both ports as forwarding/root (C610 is root bridge) with a cost of 4. But i think the C610 firmware is buggy. This switch is responding poorly when the LAG is active, ping times go to 12 - 100 ms. At some point, even the whole path seems to stop working, as if RSTP started to block the LAG ports (lost all connection). When i pull one of the ethernet ports, it all works again.
(is there any way to pull logs?)
Also the RSTP tab is not loading at times, or the system tab is reporting 'lost connection' for no obvious reason (even when LAG is off).

Are there know bugs with this device?

Thanks in advance.
