NOTE: IGMP Snooping software examines internet group management protocol (IGMP) protocol

messages within a VLAN to determine the interfaces that are connected to hosts or other devices

accepted in receiving this traffic. Using the interface information, IGMP Snooping can reduce the

bandwidth consumption in a multi-access LAN environment to avoid overloading the entire VLAN.

IGMP Snooping tracks ports that are attached to multicast-capable routers to manage IGMP

membership report forwarding. It also responds to topology change notifications. For IPv6,

Multicast Listener Discovery (MLD) is essentially the same as IGMP in IPv4.

IP Addresses and VLANs

The Dell EVO:RAIL ships a default configuration, see EVO:RAIL default configuration table. In particular,

management traffic is configured untagged and must be able to go into a native VLAN on your TOR

switch, or unable to create the appliance and ESXi hosts successfully. (All other traffic — vSphere vMotion,

Virtual SAN, and VM traffic are tagged for the VLANs you specify during configuration.)

NOTE: To customize the initial management VLAN ID for EVO:RAIL, see Appendix C:EVO:RAIL

Appliance Customization.

To configure EVO:RAIL or vCenter Server initially set the IP address to 192.168.10.200, netmask to

255.255.255.0, and gateway to 192.168.10.254.

Before turning on your appliance, ensure that EVO:RAIL IP addresses and system IP address is not same.

Table 3. IP address and VLAN requirements

IP address VLAN requirements

EVO:RAIL or vCenter Server

• IP address is required

• Netmask and gateway addresses are

automatically set to the same as the ESXi hosts

vSphere vMotion

• Continuous IP range is required, with a

minimum of 4 IPs

• Isolated VLAN preferred (network is not

routable)

Virtual SAN

• Continuous IP range is required, with a

minimum of 4 IPs
