200 ISLs with fewer than 16 VSANs,
or fewer than 200 ISLs with more than
16 VSANs, within the total ports per
VSAN instance limit of 3200.

1.
Certain design considerations must be met to reach this limit. We recommend that you have the large Fabric design validated by Cisco Advanced Services.
2.
This is the number of trunking-enabled ISL ports multiplied by the number of VSANs in the switch.
3.
SANTap is not supported in SAN-OS Release 3.3(1).
