2. If the network is flat using a single broadcast domain, skip to step 3. If using VLANs, begin configuring
VLAN interfaces using the following command:
Command
Example
interface ethernet node/slot/port
description desc_text
switchport mode trunk
switchport trunk allowed vlan vlan-id
interface ethernet 1/1/1
description "Appliance 1 Port 1"
switchport mode trunk
switchport trunk allowed vlan 110,120,130
no ip address
The commands above are common for all VLAN interfaces. Repeat the steps above for each VLAN.
For complete examples, see the running configurations in the Configuration examples section.
3. Enable IGMP snooping on the vSAN VLAN in this example configuration. Required for VxRail releases
before release 4.5. Do this with the following global command:
ip igmp snooping enable
4. Enable the ip igmp snooping querier function on the vSAN VLAN interfaces through the VLAN interface
mode command. Configure the ip igmp snooping querier with an IP address.
Command
Example
interface vlan vSAN VLAN ID
ip igmp snooping querier
ip address ip-address /subnet mask
interface vlan120
ip igmp snooping querier
ip address 192.168.120.251/24
5. Validate your configurations with the following commands
a. Switch-1(conf-if-vl-1)# show ip igmp snooping interface vlan 120
Vlan120 is up, line protocol is up
IGMP snooping is enabled on interface
IGMP snooping query interval is 125 seconds
IGMP snooping querier timeout is 255 seconds
IGMP snooping last member query response interval is 1000 ms
IGMP snooping fast-leave is disabled on this interface
Note: The IPv4 multicast requirement (ip igmp snooping enable and ip igmp snooping querier) is a
requirement of vSAN 6.0. Configure IPv4 multicast correctly for the vSAN deployment portion. IP IGMP
snooping querier requires an IP address. This interface enables IGMP snooping querier.
