What is an Expansion Port (E_Port)?

What does E_Port stand for?

An Expansion port (E_port) is an inter-transfer port used in Fiber Channel Topology to connect fiber Switches. An E_port is connected to some other E_port to create an inter-transfer Hyperlink (ISL). The E_port incorporates Frames among switches, which might be used for material control and Configuration. It Functions as a channel between switches for frames which might be meant for Node Ports (N_port), Node Loop ports (NL_port) or Nx_ports.

What Does Expansion Port Mean?

A fiber channel is a high-speed Network that connects a number of Computer Systems and gives a reliable and far flung OS Interface that requires excessive Bandwidth. The E_port is the factor wherein frames pass between fabric switches. A body with a destination exits a nearby transfer through an E_port, unless the frame is intended for the switch, N_Port or NL_Port. After a frame passes thru the E_port, it's far Forwarded to a nearby or very last destination.

Each E_port has a unique name in the fabric. An interactive sySTEM language (ISL) is used to transmit and acquire frames inside the material, N_port and NL_port. The E_port supports Class 2, Class three and Class F offerings.
