How to setup LAG between 2 Netgear switches?
I'm trying to setup LAG between 2 Netgear switches, but its not working. The switches I'm using are S3300-52X-PoE+ ProSAFE 48-Port Gigabit Stackable Smart Switch with PoE+ and 4 10G uplinks and XS728T ProSAFE 28-Port 10-Gigabit L2+ Smart Switch
On the 52 port switch, I'm using ports 51 and 52, and on the other switch I'm using ports 27 and 28, both LAG 1. I do have VLANs, so I removed VLAN 3 from ports 51 and 52, and assigned to LAG 1 (lag on 52 port switch), and on the other switch, removed VLAN 3 from ports 27 & 28, and assigned it to LAG 1 (lag on the 28 port switch)
And when I connect the SFP+ cables, I'm loosing ping. I can see the link lights on the SFP+ cables. This is my first time setting up LAG, what am I doing wrong? I'm trying to make a 20 Gb LAG between the 2 switches.
This is the KB that I'm following, but it looks old.

Here again, the same setings must be used on both ends. And for the obvious (?) reasons, only one VLAN can be run untagged and with the same PVID configured.

Not sure if this matters, but on the LAGs, I'm using it as untagged (U), do I need to use trunk (T)? So from the 52 port switch (U) to the 28 port switch (U), should I be using 52 port switch (T) to the 28 port switch (T)?
Have changed the two SFP+ ports from stacking- to Ethernet-mode?

Is there another link - direct or indirect - between the two swtches? Appears it is - because of no connection, no ping ... with a loop, with STP/RSTP being active globally on all connections, the links and/or the LAG can be shutdown due ot the loop situation.
On the S3300 52 port switch, the SFP+ ports 51,52 were already set to Ethernet. And when I go to ports, I can see that these ports are labeled 'Trunk-Member' on this switch and the 28 port switch.
Currently I do have an ethernet cable as the trunk, but when I connect the SFP+ cables to both switches, I'm disconnecting the ethernet trunk.
The only thing that I can think it that may be I bought the wrong type of SFP+ cables?
I think the problem is that my LAG Type is still set to Static. It says Static disables LCAP, but setting to LCAP enables it.
LAG Type. Specify whether the LAG is configured as a static or LACP port.
- Static—Disables Link Aggregation Control Protocol (LACP). The port does not
transmit or process received LAGPDUs, for example the member ports do not
transmit LAGPDUs and all the LAGPDUs it can receive are dropped. The LAG is
configured manually. The default is Static.
- LACP—Enables Link Aggregation Control Protocol (LACP) on the selected LAG.
The LAG is configured automatically.
