Chapter 32 Configuring Fibre Channel Interfaces Information About Fibre Channel Interfaces Send feedback to [email protected] Interface States The interface state depends on the administrative configuration of the interface and the dynamic state of the physical link. The following sections describe the states and configuration that influence the state: • Administrative States, page 32-5 • Operational States, page 32-5 • Reason Codes, page 32-5 Administrative States The administrative state refers to the administrative configuration of the interface. Table 32-1 describes the administrative states. Table 32-1 Administrative States Administrative State Up Down Description Interface is enabled. Interface is disabled. If you administratively disable an interface by shutting down that interface, the physical link layer state change is ignored. Operational States The operational state indicates the current operational state of the interface. Table 32-2 describes the operational states. Table 32-2 Operational States Operational State Up Down Trunking Description Interface is transmitting or receiving traffic as desired. To be in this state, an interface must be administratively up, the interface link layer state must be up, and the interface initialization must be completed. Interface cannot transmit or receive (data) traffic. Interface is operational in TE mode. Reason Codes Reason codes are dependent on the operational state of the interface. Table 32-3 describes the reason codes for operational states. Table 32-3 Reason Codes for Interface States Administrative Configuration Up Down Up Operational Status Up Down Down Reason Code None. Administratively down. If you administratively configure an interface as down, you disable the interface. No traffic is received or transmitted. See Table 32-4.
