Cluster interconnect and high-availability (HA) traffic

Answer

The following platforms support the sharing of cluster interconnect (CI) traffic and high-availability (HA) traffic over the same physical Ethernet port:

Model	Link to Documentation
AFF A50, AFF A30	40/100GbE CI: Shared with cluster interconnect 10/25GbE CI: Dedicated HA on ports e4a and e4b
AFF A20	Shared with cluster interconnect
AFF A250, AFF C250	Shared with cluster interconnect on ports e0c and e0d
AFF A90, AFF A70	40/100GbE CI: Shared with cluster interconnect on ports e1a and e7a 10/25GbE CI: Dedicated HA on ports e1a and e7a
AFF A1K	40/100GbE CI: Shared with cluster interconnect on ports e1a and e7a 10/25GbE CI: Dedicated HA on ports e1a and e7a
AFF C60, AFF C30	40/100GbE CI: Shared with cluster interconnect 10/25GbE CI: Dedicated HA on ports e4a and e4b
AFF C80	40/100GbE CI: Shared with cluster interconnect on ports e1a and e7a 10/25GbE CI: Dedicated HA on ports e1a and e7a
ASA A50, ASA A30, ASA A20	Shared with cluster interconnect
ASA A250, ASA C250	Shared with cluster interconnect on ports e0c and e0d
ASA A90, ASA A70	40/100GbE CI: Shared with cluster interconnect on ports e1a and e7a 10/25GbE CI: Dedicated HA on ports e1a and e7a
ASA A1K	40/100GbE CI: Shared with cluster interconnect on ports e1a and e7a 10/25GbE CI: Dedicated HA on ports e1a and e7a
FAS2820	Shared with cluster interconnect on ports e0a and e0b
FAS500f	Shared with cluster interconnect on ports e0c and e0d
FAS70, FAS90	40/100GbE CI: Shared with cluster interconnect on ports e1a and e7a 10/25GbE CI: Dedicated HA on ports e1a and e7a

Additional Information

HA traffic on the 1st shared cluster+HA port uses VLAN 17 while HA traffic on the 2nd shared cluster+HA port uses VLAN 18
VLAN 17 and 18 traffic is not passed over the cluster switch inter-switch link (ISL)
- Therefore, you must always connect the 1st cluster+HA ports to switch "A" and the 2nd cluster+HA ports to switch "B" for each HA pair
  e.g. AFF A250: e0c ports connect to switch "A" and e0d ports connect to switch "B"
