    Hello,

     

    All supported SFP, SFP+ & XFP uplink connections (10gig ports only) between EX4550 can be configured as VCPs. However advantage of using dedicated VCPs on EX4550 is that you do not need additional configuration on them & they have higher bandwidth than 10gig ports.

     

    Regards,

    The Virtual Chassis fast failover feature is a hardware-assisted failover mechanism that automatically reroutes traffic and reduces traffic loss in the event of a link or switch failure. If a link between two members fails, traffic flow between those members must be rerouted quickly so that there is minimal traffic loss. Fast failover is enabled by default on dedicated Virtual Chassis ports (VCPs). You must manually enable fast failover on uplink ports that have been configured as VCPs or on EX3300 uplink ports that are configured as VCPs by default. Cheers !!!
