Glossary community name (SNMP) A name that represents a simple network management protocol (SNMP) community that the agent software recognizes as a valid source for SNMP requests. A product recognizes a management station as a valid recipient for trap information when the station's community names are configured. community profile Information that specifies which management objects are available to what management domain or SNMP community name. concurrent firmware upgrade Firmware is upgraded without disrupting switch operation. concurrent maintenance Ability to perform maintenance tasks, such as removal or replacement of field-replaceable units (FRUs), while normal operations continue without interruption. See also nondisruptive maintenance. configuration data Configuration data includes identification data, port configuration data, operating parameters, SNMP configuration, and zoning configuration. A configuration backup file is required to restore configuration data if the control processor (CTP) card in a nonredundant director is removed and replaced. connectionless Nondedicated link. Typically used to describe a link between nodes that allows the switch to forward Class 2 or Class 3 frames as resources (ports) allow. Contrast this type of link to the dedicated bandwidth that is required in a Class 1 Fibre Channel Service point-to-point link. connectivity attribute In S/390 mode, the characteristic that determines port address status for the director or switch. See also allowed connection, blocked connection, connectivity capability, connectivity control, dynamic connection, dynamic connectivity, and unblocked connection. connectivity capability (1) The capability that allows attachment of a device to a system without requiring physical reconfiguration of either the device or the interconnections. (2) The director or switch capability that allows logical manipulation of link connections to provide physical device attachment. See also active port address matrix, connectivity attribute, and connectivity control. connectivity control In S/390 mode, in a director or switch, the method used to change port address connectivity attributes and determine the communication capability of the link attached to the port. See also active port address matrix, connectivity attribute, and connectivity control. Directors and Edge Switches Glossary 9
