4.4 Global switch settings
1. Power-on the switch and connect laptop's serial cable to the Dell EMC S4148-ON console port.
2. Configure the hostname and management port IP address:
Switch-1 (S4148-ON)
Switch-2 (S4148-ON)
hostname Switch-1
interface mgmt 1/1/1
no shutdown
no ip address
ip address 100.67.171.35/24
ipv6 address autoconfig
management route 100.67.0.0/16
100.67.171.254
hostname Switch-2
interface mgmt1/1/1
no shutdown
no ip address
ip address 100.67.171.34/24
ipv6 address autoconfig
management route 100.67.0.0/16
100.67.171.254

4.5 VLT configuration
In this example, configure the VLTi interconnect between the two Dell EMC S4148F-ON switches. The VLTi
synchronizes layer 2 table information between the switches and enables them to appear as a single logical
unit from outside the VLT domain. Compute nodes can utilize LACP LAG to the pair of VLT switches, for an
active/active L2 multipathing scenario. The dedicated vSAN links do not utilize the VLT feature and make use
of VMware's load balancing on a distributed port group through route based on physical NIC load.
Use VRRP for gateway redundancy with vSAN and management VLANs. VRRP is an active/standby first
hop redundancy protocol (FHRP). When used among VLT peers, it becomes active/active. Both VLT peers
have the VRRP virtual MAC address in their FIB table as local destination address. This allows the backup
VRRP router to forward intercepted frames whose destination MAC address matches the VRRP virtual MAC
address.
