Virtual Connect Maximum number of Downlinks

Borja had a VC question:




One of the enhancements of VC FW 3.51 is supposed to be:


Increased mapped VLAN capacity—The number of VLANs supported in a shared uplink set is

increased from 128 to 1000. The number of connections on a server downlink has been

increased from 28 to 162. Additional CLI and GUI commands have been added to support

management of multiple networks with a single command.


However, in a VC environment recently upgraded to 3.51, we still seem to have the same limitation.




Reply from Massimo:




You need to enable the “expanded” VLAN capacity here :






Any other questions?
