In this configuration
8 uplink ports on VAST Mellanox ONYX OS switches
4 on each VAST Mellanox ONYX OS switch
These 4 links are divided into to groups, each with 2 links
Two groups are connected to two different Cisco Nexus switches
Fully redundant uplink connection between VAST Mellanox to Cisco switches
Instructions
Cisco Nexus 5696 Chassis (“Nexus 5696 Supervisor”)
Intel(R) Xeon(R) CPU @ 1.80 with 16511892 kB of memory.
Processor Board ID FOC20433Q96
Software
BIOS: version 2.1.0make sure vpc and lacp are enabled
feature lacp
feature vpcFor example
Cisco configure VLAN 515 and port channel 41 on their switch for uplink ports, we need to configure port channel 41 to be access mode and vpc 41 should be configured on both Cisco switches so 8 uplinks are treated as a single channel, to match our MLAG across all 8 uplink ports on our Mellanox switches
