Use to segment Fabric Services into logical "SAN Islands" FLOGI, FC Domain, FC Name Server, Zoning, Aliases, etc. The above would be per VSAN basis Configuration vsan database vsan 10 vsan 10 interface fc1/1 VSAN doesn't equate to how can talk to how within the SAN, but just creating separate copies of the fabric services VSAN's and E ISL's All VSAN's allowed on trunk port by default (Similar to Ethernet Bride Assurance) Remotely un-configued VSAN's automatically "pruned" off trunk ports is remote device does not have a particular VSAN configured. To avoid merging fabrics, VSAN's should be pruned manually "switchport trunk allowed vsan" Design Configuration N5K1 conf t vlan database vsan 10 vsan 30 vsan 30 interface fc1/31 It will ask you if you want to continue because it might impact the port (disrupted) have to re-register with the fabric services (send out FLOGI) vsan 10 interface fc1/32MDS1 conf t vlan database vsan 10 vsan 30 (in the transit path for VSAN 30) not assigning to a link vsan 40 vsan 10 interface fc1/17 vsan 40 interface fc1/18 MDS2 conf t vlan database vsan 20 vsan 30 vsan 40 (in the transit path for VSAN 40) not assigning to a link vsan 30 interface fc1/14 vsan 20 interface fc1/13 N5K2 conf t vlan database vsan 20 vsan 40 vsan 20 interface fc1/32 vsan 40 interface fc1/31 Now show int brief | in TE Show int fc1/13 trunk vsan You can dis allow VSAN 10 from port fc1/13 with: config t int fc1/13 switchport trunk allowed vsan 30 switchport trunk allowed vsan add 40 Show running-config from N5K1 In the above example you would usually only have two VSAN's the would denote SAN A and SAN B |
