Some of the features are similar to apply both standard and distributed switch. It is possible to apply only in Distributed switch only.įeatures similar in both standard switch and distributed switch As a VM moves from host to host on a vNetwork Distributed Switch. Networking vMotion – Networking vMotion tracking virtual machine networking state. Networking vMotion is used in Distributed switch only. Inbound traffic shaping is possible to apply in distributed switch only. vSphere Distributed switch include rollback and recovery for patching and updating network configuration, templates to enable backup and restore for virtual networking configuration. vSphere Distributed switch given priority to traffic and allows other network streams to utilize available bandwidth. It Provides centralized management and monitoring of the network onfiguration of all the ESXi hosts that are associated with the dvswitch. Distributed switches allow different hosts to use the switch as they exist in same host. vSphere Distributed switch on a datacenter to handle the networking configuration of multiple hosts at a time from a central place. VSphere Distributed switch allows a single virtual switch to connect multiple Esxi hosts. Networking vMotion is not available in standard switch. Inbound traffic shaping is not available as a part in standard switch. we can create and manage vSphere standard switch independently on ESXi host. Standard switch is created in host level i.e. This is one of the real advantages for standard switch users.
Standard switch does not require Enterprise plus licensing for usage. vSphere standard switch bridge traffic internally between virtual machines in VLAN. Standard switch works with only with one ESXi host. So can you do this? Yes you can, as long as you DO NOT specify the VLAN number on the vSwitch ‘port group’.VSphere Standard Switch is used to provide network connectivity for hosts, virtual machines and to handle VMKernel Traffic. Petes-3750# ESX/Cisco ‘Switchport Mode Access’ Interface when portfast is enabled, can cause temporary bridging loops.

Just because you are connecting to a VMware virtual switch the process is the same, even if you only have one port group and VLAN connecting to the vSwitch! You CANT configure trunking on the virtual switch (because it does not support DTP), so you need to do everything on the Cisco Catalyst Switch. Now if I was connecting two ‘real’ switches together and wanted to do this, I would need to create a ‘trunk’ port between the two switches, and ‘allow’ VLANs across the trunk, (or allow all VLANs). I had made the port on the Cisco switch an ‘access port’, so I could never add another port group with another VLAN, that’s probably why it’s not working”.
I was pondering on this during my drive home, and the thought struck me, “I’ve got a ‘port group’ in VLAN 200.
No entries in the switch MAC address table, no bytes being transmitted from the VM, nothing? Solution I configured this switch as an ‘access port’ in VLAN 200, I made sure VLAN 200 had an IP address (an SVI address on the switch). This is patched into a Cisco 3750 Catalyst switch. Now you can see (above), I’ve presented one physical NIC to this vSwitch (vmnic1). Or if you prefer to work in the fat client.
I was trying to carve off some hosts into their own VLAN today, and setup a new vSwitch. If you don’t need different virtual machines to be in different VLANS on your vSphere/ ESXi servers then you probably just connect everything together and it all works fine.
