The F_Port is the Fabric access port used to connect an N_Port. The FL_Port is the fabric access port used to connect NL_Ports to the switch in a loop configuration. The NL_Port is the designation of an equipment port connected to the fabric in a loop configuration via an FL_Port. The POST is a series of self-tests that run each time the unit is booted or reset. Fibre-Channel shortest path first. A port is designated as a G_Port when it has not assumed a specific function. A G_Port is a generic switch port that can operate either as an E_Port or an F_Port. A port is defined as a G_Port, for example, when it is not connected or has not yet assumed a specific function in the fabric. R_A_TOV is used to time out operations that depend on the maximum possible time that a frame could be delayed in a fabric and still be delivered. The value of R_A_TOV is adjustable in 1-microsecond increments over a range from 10 to 120 seconds. Hardware that connects incompatible networks by providing the necessary translation, both for hardware and software. ISL is a fiber link between two switches SNMP is a TCP/IP protocol that generally uses the User Datagram Protocol (UDP) to exchange messages between a management information base and a management client residing on a network. Since SNMP does not rely on the underlying communication protocols, it can be made available over other protocols, such as UDP/IP. ISL is online but not operational between switches because of overlapping domain ID or nonidentical parameters such as E_D_TOVs. The original standard for SNMP is now referred to as SNMPv1. A loop is a configuration of devices (for example, JBODs) connected to the fabric via and FL_Port interface card. A trap is a mechanism for SNMP agents to notify the SNMP management station of significant events. Multicast is used when multiple copies of data are to be sent to designated multiple destinations. Unicast routing provides one or more optimal path(s) between any of two switches that make up the fabric. This is for a single copy of the data to be sent to designated destinations. The N_Port is the designation of an equipment port connected to the fabric. Unique numeric identifier for each switch; assigned by manufacturer. 2 Dell PowerVault Switch Manager User's Guide
