2 interfaceShow interfaceShow Displays FSPF interface information. SYNOPSIS interfaceshow [slot/][port] DESCRIPTION Use this command to display the two data structures associated with FSPF interfaces (E_Ports) on the switch: • The permanently allocated interface descriptor block (IDB). • The neighbor data structure. This data structure is allocated when a switch port becomes an E_Port. The neighbor data structure contains all the information relating to the switch that is connected to an adjacent switch. This command displays the content of both data structures, if they have been allocated. The following fields are displayed: idbP Pointer to IDB. nghbP Pointer to neighbor data structure. ifNo Interface number. masterPort Port number of the trunk master port, if present, of the trunk group of which this port is a part. defaultCost Default cost of sending a frame over the interswitch link (ISL) connection to this interface. cost Cost of sending a frame over the ISL connected to this interface. A value of 1000 indicates a 1-Gbps link. A value of 500 indicates a 2-Gbps link. For links with a bandwidth greater than 2 Gbps, the cost is 500. For links with less than 1 Gbps, the cost is 2000. Refer to linkCost for more information. delay Conventional delay incurred by a frame transmitted on this ISL. A fixed value required by the FSPF protocol. lastScn Type of the last State Change Notification received on this interface. lastScnTime Time the last State Change Notification was received on this interface. upCount Number of times this interface came up, with respect to FSPF. lastUpTime Last time this interface came up. downCount Number of times this interface went down. lastDownTime Last time this interface went down. 456 Fabric OS Command Reference 53-1002746-01
