Help M7100 MLAG is driving me mad
Morning everyone .. i am looking to get some form of help from the community about a frustrating sets of problems we are having with MLAG and 4 M7100s switches .I would hopefully receive back a runni...
Thank you, DaneA
Let me add the following:
On SW1 and SW2, you can only connect devices by using LAGs. Therefore, a PC with a single NIC card that is connected to either SW1 or SW2, will not be able to communicate with Lab Switch if the single NIC PC isn't connecting to an MLAG. This is a limitation and we know this is "consuming" one port on the other switch that will never be used. But this is the only solution. Please create one MLAG across SW1 and SW2, and connect the "orphan" PC to SW1 this way. Please create another MLAG to connect another "orphan "PC" to SW2.
Etc.
This is not elegant, that's why we enhanced our Stacking technology in more recent generation switches (M4300 series) for allowing spine and leaf stacking between 1G and 10G models, distributed LAG across the stack with Non-Stop Forwarding (LACP), etc.
I hope this will help.
Regards,
Hi Laurent and thanks for the info
However i am aware and accepted from the begginning the limitations and were planning to connect the hosts to any of sw1-2-3-4 switches always with the connection (sw1 and 2 or sw3 and 4)
the goal was to communicate with an (single or double carded) host connected to the lab switch .Wtih the given configs I tried all the matrix (single and bonded connection on both sides)
with no success except connectiong from the sw1-2 mlag to the labswitch ip
In the meantime i opened a support case with the support and received a configuration from your lab
I have to test it yet and hope to do it before the end ./ beginning of the next week and will share the results
thanks for now
