I'm front of a big deal with PVLANs, How to do an Etherchannel with two ports configured with PVLAN trunk promiscuous between 4510 and 7609. Is is possible ? If not, how to workaround this ?
It is not possible to configure Etherchannel with PVLAN trunk ports between 7609 and 4510.
Do not configure private VLAN ports as EtherChannels. A port can be part of the private VLAN configuration, but any EtherChannel configuration for the port is inactive.
