The F_Port is the fabric access port used to connect an N_Port. and still be delivered. The value of R_A_TOV is adjustable in 1-microsecond increments over a range from 10 to 120 seconds. Fibre-Channel shortest path first. Gigabit interface converter. A removable serial transceiver module designed to provide gigabaud capability for Fibre Channel and other protocols that use the same physical layer. 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. ISL is online but not operational between switches because of overlapping domain ID or nonidentical parameters such as E_O_TOVs. 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. Because SNMP does not rely on the underlying communication protocols, it can be made available over other protocols, such as UDP/IP. ISL is a fiber link between two switches. 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 an 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. The N_Port is the designation of an equipment port connected to the fabric. 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 which run each time the unit is booted or reset. 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. A port is designated as a U_Port when it has not assumed a specific function. A U_Port is a generic port that can operate either as an E_Port, an F_Port, or an FL_Port. A port is defined as a U_Port, for example, when it is not connected or has not yet assumed a specific function in the fabric. R_A_TOV (Resource Allocation Time Out Value) used to time out operations that depend on the maximum possible time that a frame could be delayed in a fabric A WWN uniquely identifies a switch on local and global networks. 2 Dell PowerVault 51F 8-Port Fibre Channel Switch User's Guide
