Hi, I have pair of cisco Nexus3064T Chassis ("48x10G Base-T + 16x10G/4x40G Supervisor") and QSFP-H40G-CU1M 40GBASE-CR4
I did connect each switch via QSFP-H40G-CU1M
I see now what 4 interfaces are UP
Eth1/49/1 1 eth access up none 10G(D) --
Eth1/49/2 1 eth access up none 10G(D) --
Eth1/49/3 1 eth access up none 10G(D) --
Eth1/49/4 1 eth access up none 10G(D) --
My question here, can you have one 40G interface instead of 4x10G? I tried following command, but without success
swich-A(config)# interface ethernet 1/49/1-4
swich-A(config-if-range)# speed 40000
ERROR: Ethernet1/49/1-4: Configuration does not match the port capability.
I'm running version 6.0(2)U2(2), but saw some limitation in 6.0(2)U3(6) but I'm not sure i fully understand what is going on :-)
I'm fine with doing port-channel with LACP by hands, but if someone can share a light it would be great!
