What is a converged interface? Thank you.

Port aggregation can treat multiple physical connections as a single logical connection, allowing two switches to simultaneously transmit data through multi-port parallel connections to provide higher bandwidth, greater throughput and recoverability. Generally speaking, the maximum bandwidth of the connection between two ordinary switches depends on the connection speed of the medium (100BAST-TX twisted pair 200M). Trunk technology can be used to bind four 200M ports into a connection with a maximum of 800M. The advantage of this technology is that it can increase the bandwidth by binding multiple ports at a lower cost, and the increased overhead is only the ordinary five-class network cable used for connection, which occupies more ports. It can effectively improve the uplink speed of the subnet, thus eliminating the bottleneck of network access. In addition, Trunk also has automatic bandwidth balance, that is, fault tolerance function: even if Trunk has only one connection, it will still work, which invisibly increases the reliability of the system.
