You cannot create an Etherchannel or LACP with ports connected to different switches You could create two Etherchannel (one cge0 and cge1 to switch1 the other cge2 and cge3 to switch2) and the a Fail Safe Network (FSN) on top of those 2 Etherchannels As for the FSN, there is a note in the documentation "Configuring and Managing Celerra Network High Availability": If the devices of a FSN are connected to different switches, it is critical that all switch ports of the FSN be configured to immediately switch from blocking mode to forwarding mode and not pass through spanning tree states of listening and learning when an interface comes up. On Cisco switches, this means the portfast capability must be enabled for each of the ports connected between the switch and the constituent devices of the FSN.This is necessary to guarantee that the switch forwards the Ethernet frame that the Data Mover generates when a physical link is enabled. This is done on a port-to-port basis. The portfast variable, when enabled, causes the port to immediately switch from blocking to forwarding mode. It is important that you do not use portfast on switch-to-switch connections.If you notice a FSN device toggling between components, it might be because a primary device is configured and the primary device is having intermittent failures  Claude
hi i have cge0 and cge1 connect to cisco switch 1 cge2 and cge3 connected to different cisco switch2  can i crate etherchannel for cge0 cge1 cge2 and cge3 what the best network configuration in this case 
etherchannel
