We recentely ran into a limit on number of links allowed for devices connected to nexus 2k. Currently there is only support for (1) 1GB link to Each of the 2 Nexus 2k. See Below.
The question i have is if this is a hardware limitation or a software limitation and if there is any insight on future support for higher capacity etherchannels.
From Config Guide
The current generation of Cisco Nexus 2000 Series Fabric Extender does not support EtherChannels on its host interfaces. Therefore a maximum of two links can be configured in an EtherChannel from the server where each link is connected to a separate Fabric Extender.
Thanks in advance
