What is the function of a distributed switch?
A distributed switch functions as a single virtual switch accross all associated ESXi hosts and allows virtual machines to maintain consistent network configuration as they migrate across multiple hosts.
What are the benefits of distributed switches?
Distributed switches allow different hosts to use the switch as they exist in same host. It Provides centralized management and monitoring of the network onfiguration of all the ESXi hosts that are associated with the dvswitch.
What is vNetwork distributed switch?
A vNetwork Distributed Switch is an aggregation of per-host virtual switches presented and controlled as a single distributed switch through vCenter Server at the Datacenter level. The vDS abstracts configuration of individual virtual switches and enables centralized provisioning, administration, and monitoring.
What is a dvPort group?
dvPort groups aggregate multiple ports under a common configuration and provide a stable anchor point for virtual machines connecting to labeled networks. Each dvPort group is identified by a network label, which is unique to the current datacenter.
What features does a distributed switch support?
Simplified Virtual Machine Network Configuration Central control of virtual switch port configuration, portgroup naming, filters and others settings. Link Aggregation Control Protocol (LACP) support to negotiate and automatically configure link aggregation between vSphere hosts and the access layer physical switch.
How many uplinks are needed for a distributed switch?
You should have at least two uplinks configured for a VDS to allow for redundancy.
How many hosts can be on a distributed switch?
Each VMware vCenter Server instance can support up to 128 VDSs; each VDS can manage up to 500 hosts.
What is distributed switch in VMware?
VMware vSphere Distributed Switch (VDS) provides a centralized interface from which you can configure, monitor and administer virtual machine access switching for the entire data center. The VDS provides: Simplified virtual machine network configuration. Enhanced network monitoring and troubleshooting capabilities.
What license type do you need to use distributed switches?
VMware distributed switching is available only if you use the vSphere Enterprise Plus license for ESXi hosts in vSphere. If you use a free trial license, all vSphere features including a distributed virtual switch are available for a 60-day period.
How many hosts can be on a virtual distributed switch?
What is required to create a vSphere distributed switch?
A minimum of two physical uplinks is required. vSphere Enterprise Plus licensing is required. The host is added to a vCenter Server. Login to the ESXi Host with the Root account.
What is the maximum number of ESX hosts we can connect to a single distributed switch?
A maximum of 64 hosts can connect to a single DvSwitch and up to 16 distributed switches can be implemented per host. DvSwitches are stored to the VMkernel, but the settings linked to the DvSwitch are contained in the vCenter database.
How does a distributed switch work in VMware?
The VMware distributed switch provides a single interface for managing virtual switches centrally on all ESXi hosts associated with that distributed virtual switch. The VMware distributed switch configuration is like a template that is applied to all ESXi hosts and similar standard virtual switches are created on those ESXi hosts automatically.
What are the privileges of a distributed port group?
Distributed virtual port group privileges control the ability to create, delete, and modify distributed virtual port groups. [Read more] Distributed Switch privileges control the ability to perform tasks related to the management of Distributed Switch instances. [Read more]
How is the VSS different from the distributed switch?
The virtual machine network adapters and physical NICs on the ESXi host use the switch’s logical ports as each adapter uses one port. Each logical port on the VSS is a member of a single port group. One of the key differentiators between the vSphere Standard Switch (VSS) and the vSphere Distributed Switch is where the management resides.
Can you set direct permissions on a VM?
You cannot set direct permissions on the VM, host, network, and storage folders. That is, these folders act as containers, and as such are not visible to users. You cannot set permissions on standard switches. Most inventory objects inherit permissions from a single parent object in the hierarchy.
