We have four 9200L switches stacked together. I am trying to config it to connect to our core switch(Mellanox SN2100 100G switch) using LACP trunking. After play around I can't figure out why it won't pass traffic to my core switch. I need some help here. Thank you.
Here are some details:

3. Test:
Connect my notebook (Static IP 10.36.14.100 on vlan 14) to port 1/0/1 (access port vlan 14), ping gateway 10.36.14.1 which is on core-02 failed.
Can someone give me helps? Thanks a lot.

For testing can you use a single physical port (no portchannel) from each switch a test again?
Example:
1/1/1-----1/8/1

I tried to config a single 10G port as trunk but it still not working. It may caused by the transceiver I am using (3rd party generic). When I make a 1G port as trunk then the traffic pass through fine.
I am going to order the Cisco transceivers and test it again.
