LAG not working unless you specify interface speed

Hi,

mayba I have the same issue here. XGS with SFOS 18.5 MR2. Created LAG with LACP for two ports but I only can reach/ping the LAG interface and no VLANs on the LAG. If I switch the mode to Active-Backup everything is working.

Other than yours I can´t change the interface speed, there is only "Auto Negotiation" in the drop-down field.

Hello,

Can you check from the command line interface 
1.) console> show network lag-interface
2.) show network lag-interface <lag interface> runconfig

To verify if all the Port members are present, are up and share the same negotiation ? 

It is currently a known issue and currently under investigation. Bug ID to track: NC-92783

Both ports are up and members...

For me this looks okay.

LuCar Toni I can´t find the bug ID in the List here: sophos.my.salesforce.com/.../OB6B.SqGNZ6icEOHK1vpKhgiPKV9zvRsyUKM5ecfUtE

Because it is not published yet. Most IDs will be only published after the issue is confirmed and will be fixed. 

You can create a Support ID and relate to this ID. 

Hello Martin Nowak,

This is surely related to the new Bug ID as LuCar Toni - "NC-92783"  mentioned, and the only work around is : "Changed speed settings to manual 10G and it started working."

I can live with the Active-Backup state for now but how do I change the LAG interface speed? Through the XGS web console I only have auto negotioation in the drop down. Maybe this is limited to more enterprise grade XGS only? I have a XGS 116.

Or is there a console command for this maybe?

From the command line interface you try with the following: 

console> set network interface-speed <interface> speed <value> 

Did it and it shows in the interface overview but still no access from LAN to the VLANs on the LAG.

But as I mentioned, I can use Active-Backup until the fix is there.
