Abstract
F_PORTs of an edge switch are logically trunking with N_PORTs of a node device outside the fabric via a trunked group of communications links. The trunked N_PORTs of the node device and the trunked F_PORTs of the edge switch are configured to send and receive frames of a particular stream across the multiple trunked links for in-order communication with the other device. The node device outside the fabric initially negotiates with the edge switch using a sequence of fabric login requests and fabric login acceptances to establish the trunked connection between the devices (and their respective ports).
