Re: LAG (LACP) or RSTP or both???

As I understand it (R)STP will prevent a loop by blocking one of the links. In the event of a failure of one link, the (R)STP will simply use only the one working link. Yes, when configured properly (bridge priority etc...) LACP can handle 2 cables/ports because protocol supports it and it`s design...

Re: LAG (LACP) or RSTP or both???

LACP is for link aggregation. 2 ports on switch A and 2 ports on switch B. 2GB link between them with LACP. If not using LACP or static team 2 ports connected between switches would create LOOP. This is what RSTP is for. To prevent loops and lear about topology changes: https://networklessons.com/sp...

Re: LAG (LACP) or RSTP or both???

You can do and should do lacp This is exactly what you need, 2 links combined for reliability and redundance. Rstp has nothing to do with this. Lacp well there is not much to configure, it is missing long and short timeouts but thats it, there is very little configuration. Just make sure that one of...

Re: LAG (LACP) or RSTP or both???

You can`t do it with RSTP.
You can do it with:
LAG LACP
LAG Static teaming

LACP seems to be a little buggy at least for me in SwOS.

Re: CSS326 IGMP Snooping not working!

Same here, iptv uplink will flood all ports even when igmp snooping is ON and enabled on vlan.

Re: LAG, LACP mode

Also one more thing.

When I configure static teaming and assign 2 groups, under trunks there is always number 1.
Shouldn`t trunk be 1 for group 1 and 2 for group 2 ?

LAG, LACP mode

Hi all! I just got CSS326-24G-2S+. Upgraded to 2.8 firmware. Problem and steps taken: Configured LACP: - active mode - disabled RSTP for ports in LACP - disabled IGMP snooping as I don`t need it - connected 3 nics from Server 2016 to switch LACP negotiated OK. Now fun begins. If I disconnect only 1 ...
