Enable IPv6 and IGMP snooping on VLAN 3939 required for VxRail

VxRail by default requires VLAN 3939 for nodes to discover each other. Ideally on this VLAN we should enable IGMP snooping and IPv6. The same can be done for a few switch makes as follows:
Dell switch
config t ip igmp snooping enable ipv6 mld snooping enable exit show ipv6 mld snooping interface vlan 3939
Aruba or HP switch
config t vlan 3939 ip igmp ipv6 enable ipv6 mld enable ip igmp snooping enable exit show ip igmp snooping vlan 3939

Cisco switch
config t ipv6 unicast-routing ip igmp snooping ip igmp snooping vlan 3939 ip igmp snooping querier vlan 3939 ip igmp snooping end show ip igmp snooping show ip igmp snooping vlan 3939 show ipv6 interface show ipv6 mld snooping interface vlan 3939
Optionally we can consider removing storm-control for multicast and max-group settings, if above is not enough
no storm-control multicast show running-config interface <int-name> config t int <int-name> no ip igmp max-groups <number>
Creating VLAN 3939 on old Cisco Switches
On old Cisco switch VLANs might be restricted to 1024 only. If it is acceptable to environment shift to VTP version 3 and try. If it still does not works change vtp mode to transparent. In transparent mode the switch wont participate in VTP, neither as client and nor as server.
config t vtp version 3 vlan 3939 name vxrail no shut exit #if above gives error then vtp mode transparent vlan 3939 name vxrail no shut end show vlan brief
