Hi All

I wanna a clear and simple explanation for the following

vlan port count optimization

port vlan membership 

I see many explanation at cisco.com but could not understand

Hi Amr

•Enable higher scale in logical ports (also called P,V ports)

•Important for customers with:

•ESX DVS or Nexus 1kV

•Multi-tenant – Service Provider/Enterprise

•High # of Servers with high # of VLAN – GET/Enterprise/Commercial/SLED

•Optimizes (P,V) to increase supported limit

•Increase Scale from 32K to up to 64K* on the Fabric Interconnect 6248/6296

•Example

•5 clusters of 32 ESX hosts (160 hosts total)

•Each ESX host has 4 static vNICs (2 per fabric)

•Each cluster has 150 VLANs that do not overlap across clusters

•Each vNIC carries 150 VLANs

•Number of VIFs: 160 x 4 = 640

•8 Ethernet border ports carrying all the VLANs

•Number of VLANS: 5 x 150 = 750

•PV count = 160 x 2 x 150 + 8 * 750 = 54,000
