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. prgm_if_id Internal variable curr_if_id Internal variable prgmCnt Number of remote domains the link has been programmed to reach for routing traffic. 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. ifBw The rounded bandwidth of the interface, in Gbps. totalBw The summed total bandwidth for the entire trunk and ISL, in Gbps.
