Dell MXL and N4064F connectivity issue
Hi,
I Have some problem with connectivity between Dell MXL in M1000e and N4064F.
My configuration:
Stacked 2x Dell MXL with 4xSFP+ uplink
Stacked 2x Dell N4064F
On N4064F I configured LACP trunk port using 8 ports.
On MXL I configured LACP using 8 ports too (port-channel 1).
when i change port-channel1 on mxl to
no ip address
port-mode hybrid
switchport
no shutdown
mxl cli start lagging, and i getting timeouts or freeze on cli connection.
Someone can help me?

Hi Matt,
Is Spanning-tree enabled? Is the firmware up to date?

@DELL-Josh Cr yes RSTP is enabled and set lower priority on MXL Stack.
I think i have similar problem as https://www.dell.com/community/Networking-General/M1000e-Force10-MXL-Possible-Loop-when-connected-with-CMC/td-p/6131472
I have management network as native vlan, and I connect to it CMC, address MXL stack management in this network, and now when I change port-channel 1 to portmode hybrid and switchport, for a few seconds everthing seems to work well, but then i had connection problems via ssh to the MXL stack, and also a continous ping to the MXL had several interrupts. After a "no switchport" (via terminal) on port-channel 1 the network was stable again
I run firmware 9.7 on dell MXL, and latest on N4064F.
Do you have some idea how can i resolve this problem without create additional vlan for management?

It should be a separate VLAN so it doesn’t create a loop.
