To bond two 1 Gbps ports between switches to create a 2 Gbps link, which protocol should be used?

Networking lightens the load when you want more bandwidth by combining multiple physical links into one logical path. This is done with a port-channel that pools the capacity of the included links. The protocol that handles this negotiation and management is LACP. It talks to the other switch, confirms both ends can form the channel, and keeps the links synchronized. If one link fails, traffic is redistributed over the remaining active links, maintaining the connection with minimal disruption. This is why LACP is the right choice for creating a single 2 Gbps link from two 1 Gbps ports. STP prevents switching loops at layer 2 and doesn’t create a bonded, higher-capacity link. VRRP provides gateway redundancy for devices but isn’t involved in link aggregation. VLAN tagging separates traffic into different VLANs and doesn’t affect the bonding of ports.
