A 10 GbE TOR switch that is correctly configured to carry IPv4 multicast and IPv6 multicast traffic is

required. IPv4 multicast and IPv6 multicast traffic must be carried to all ports connected to EVO:RAIL on

the TOR switch. Multicast is not required on your entire network, just on the ports connected to

EVO:RAIL. To configure your TOR switch, see the VLANs section in this document.

Link aggregation, including protocols such as LACP and Ether Channel, must be disabled on all ports

connected to EVO:RAIL on the TOR switch(es) because VMware Standard Switch (VSS) does not support

this feature.

Two or more TOR switches can be used for high availability or failover. When using multiple TOR

switches, multicast traffic for IPv4 and IPv6 must be enabled on ports used for inter-switch

communication.

The network can be configured flat or with VLANs, but it is recommended to deploy EVO:RAIL with

VLANs. All VLANs must be configured on the TOR switch(es), as described in the VLANs section in this

document.

Table 3. Dell Network guidelines

Setting Mandatory/ Recommended Notes

IPv6 enabled on all ports

Eight ports for RJ-45 or SFP+ for each EVO:RAIL appliance. One port for a workstation or laptop to

access EVO:RAIL

IPv4 Multicast Mandatory for VSAN VLAN Used for VSAN network for meta

data and heart beat

communication

IPv6 multicast Mandatory for Management

VLAN

Used for EVO RAIL discovery,

update, maintenance and scaling

workflows

IGMP Snooping AND IGMP

Querier

Recommended to prevent

additional Multicast traffic.

Mandatory for VSAN if you are

sharing VSAN VLAN with other

hosts in network.

Helps restrict flooding of

multicast and non-EVO Rail

traffic to all ports. If IGMP

snooping is enabled, querier is

also required.

MLD Snooping Optional on management VLAN,

not needed on any other VLAN.

EVO RAIL IPv6 multicast traffic is

minimal and hence the flooding

has little or no impact

L3 Multicast Not needed
