CDOT cluster interconnect port trunking

[francisjkim]

Does anyone know if there's any sort of port binding (or link aggregation) going on for the ports used in cluster interconnect, whether for switched or switchless CDOT configuration?

I had assumed the cluster interconnect ports were just independent ports, with independent MAC and IP addresses, but I just heard someone mention that those ports are trunked, so I'm looking for confirmation.

Cluster ports are all independent.  Example output from a 4 node cluster w/ two cluster ports per node:

::*> network interface show -role cluster -field address

vserver lif address
---------- ----- ---------------
node01 clus1 169.254.205.241
node01 clus2 169.254.208.44
node02 clus1 169.254.75.122
node02 clus2 169.254.168.139
node03 clus1 169.254.186.217
node03 clus2 169.254.83.78
node04 clus1 169.254.183.78
node04 clus2 169.254.115.235
8 entries were displayed.

Follow-up for completeness - the connections between the two cluster switches are trunked however.  Example from one of the cluster switches in the same four node cluster example as above, which also shows that the connections to the nodes are discrete:
