Use multiple physical uplinks per vSwitch
If used, set spanning tree to be Portfast enabled on your switches link
Separate VMkernel and VM traffic (VLANs, dedicated pNICs)
Select the appropriate Load Balancing policy for your configuration
Dedicated vSwitch for each IP based storage connection (iSCSI, NFS)
Secure network for Management Network traffic
Skills and Abilities - Configure SNMP
Administration > vCenter Server Settings > SNMP
Receiver URL
Receiver Port
Community String
vicfg-snmp -E -Enable snmp
vicfg-snmp -s - Apply settings
Skills and Abilities - Determine use cases for and applying VMware DirectPath I/O
DirectPath I/O allows a VM to access PCI(e) I/O devices on the physical server natively. To achieve this the hardware of the physical server must support this (Intel VT-d and AMD-Vi) and be configured in the BIOS to allow this. You would use DirectPath I/O for taking advantage of things like 10GbE NICs.
Since vSphere 5.0, vMotion IS supported for the specific scenario of using compatible Cisco UCS configuration.
Due to these limitations use where performance is paramount but high availability less important.
Skills and Abilities - Migrate a vSS network to a Hybrid or Full vDS solution
Whitepaper: VMware vNetwork Distributed Switch: Migration and Configuration
If you have a multiple uplinks in your vSwitches you can perform the migration without outage. Remove an uplink from vStandard Switch to be migrated. Create new vDS using Wizard "Home > Inventory > Network" during wizard select the uplink you removed from vStandard Switch. Use migration wizard to migrate VMkernel ports and VMs. Remove old vStandard Switch, add remaining uplinks from old vSS to new vDS.
Skills and Abilities - Configure vSS and vDS settings using command line tools
esxcli network vswitch standard uplink remove --uplink-name=vmnic --vswitch-name=vSwitch # unlink an uplink
esxcli network vswitch standard uplink add --uplink-name=vmnic --vswitch-name=vSwitch # add an uplink
esxcfg-vswitch -Q vmnic -V dvPort_ID_of_vmnic dvSwitch # unlink/remove a vDS uplink
esxcfg-vswitch -P vmnic -V unused_dvPort_ID dvSwitch # add a vDS uplink
Skills and Abilities - Analyze command line output to identify vSS and vDS configuration details
esxcli network vswitch dvs vmware list
Netflow is a feature that was introduced on Cisco routers that give the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data that is provided by Netflow a network administrator can determine things such as the source and destination of the traffic, class of service, and the cause of congestion. Netflow consists of three components: flow caching, Flow Collector, and Data Analyzer.
Netflow data can be configured to be sent from VMware Distributed Switches to a NetFlow Connector. You can set what data is sent like all from vSwitch or only individual port groups within a vSwitch.
vSphere standard switch (Cisco Discovery Protocol only) or vSphere distributed switch (both Cisco Discovery Protocol and Link Layer Discovery Protocol).
LLDP is essentially same as CDP but is industry standard IEEE 802.1AB not Cisco propriety.
