VLAN limitations sup720

Hi

Just a quick one. Does anyone know the max number of configurable VLANs supported on the sup720? Also what is the maximum number of concurrent spanning-tree instances supported?

Re: VLAN limitations sup720

You can configure extended range vlans on sup 720 so the total number of Vlans supported are 4096.

If you have Mac-address reduction, with PVST+ you have have upto 4096 instances and with MSTP you have 16 MST instances.
