interfaceShow Displays FSPF interface information. Synopsis interfaceshow [slotnumber/][portnumber] Availability all users 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 nghbP ifNo masterPort defaultCost cost delay lastScn lastScnTime upCount lastUpTime downCount lastDownTime downReason iState state Pointer to IDB. Pointer to neighbor data structure. Interface number. Port number of the trunk master port, if present, of the trunk group of which this port is a part. Default cost of sending a frame over the ISL connection to this interface. Cost of sending a frame over the ISL connected to this interface. A value of 1000 indicates a 1-Gb/sec link. A value of 500 indicates a 2-Gb/sec link. Conventional delay incurred by a frame transmitted on this ISL. A fixed value required by the FSPF protocol. Type of the last State Change Notification received on this interface. Time the last State Change Notification was received on this interface. Number of times this interface came up, with respect to FSPF. Last time this interface came up. Number of times this interface went down. Last time this interface went down. Type of last State Change Notification that caused this interface to go down. Current state of this interface. The state can be UP or DOWN. An interface in DOWN state does not have an allocated neighbor data structure and cannot be used to route traffic to other switches. Current state of this interface. This E_Port is used to route traffic to other switches only if the state is NB_ST_FULL. Fabric OS 5.x command reference guide 305
