So I have an odd situation, and I thought I had the settings correct, but it seems that I do not.
Backstory:
I’ve currently got a dell switch, passing traffic to a CRS326-24s+2Q+. I set up SFP+1 and SFP+2 bonded. Said bonded interface is part of a bridge. I am able to pass untagged traffic on the management VLAN, correctly to tagged and untagged ports.
This switch then uses bonded interfaces to talk to another switch in a remote cabinet. Again, I’ve bonded the interfaces (This time it was SFP+21 through SFP+24) to remote switch (SFP+1 through SFP+4). The vlan for that switch comes in the primary bond on switch 1 as tagged, and is supposed to be passing the traffic untagged down to the remote cabinet bond, where the remote cabinet bond is also on it’s own bridge with that vlan as untagged, but it’s not passing traffic.
When I remove the ports from the bond, and set just one interface up on the bridge with the correct vlan untagged, it passes traffic through to the second switch. So I’m at a loss as to why the lag won’t pass the vlan untagged, but the individual port will. Below is a modified export of the two devices.
Below is the skimmed down part of the configs pertinent.
Bond is 802.3ad - mii monitoring with layer 2 transmit hash. 0 min link, 0 down delay, 0 up delay, lacp rate 30s, and mii interval 100ms.
