HP StorageWorks 8/80 Brocade Fabric OS MIB Reference v6.3.0 (53-1001339-01, Ju - Page 44

2 Interfaces group Interfaces group Implementation of the Interfaces group is mandatory for all systems. FCIP tunnel support is added in Fabric OS 5.3.0 and higher. To support FCIP tunneling, entries are created in the ifTable for each WAN interface (GbE port), each FC port, and each FCIP tunnel (transport interface). Logical Inter Switch Link (LISL) is an FC interface. ifNumber 1.3.6.1.2.1.2.1 The number of network interfaces and existing FC ports present on this system, regardless of their current state. This number will vary across platforms (switches). The return value is dynamic for all Brocade switches and depends on the number of GbE ports, FC ports and transport interfaces. ifTable 1.3.6.1.2.1.2.2 A list of interface entries. The number of entries is given by the value of ifNumber. The Interfaces table contains information on the entity's interfaces. Each interface is thought of as being attached to a subnetwork. Note that this term should not be confused with subnet, which refers to an addressing partitioning scheme used in the Internet suite of protocols. ifEntry 1.3.6.1.2.1.2.2.1 Index An interface entry containing objects at the subnetwork layer and below, for a particular interface. ifIndex ifIndex 1.3.6.1.2.1.2.2.1.1 A unique value for each interface. The values range between 1 and the value of ifNumber. The value for each interface must remain constant, at least from one reinitialization of the entity's network management system to the next reinitialization. For Network Interface, the number starts from 805306369 and increments with the interface count. For FC ports, the number starts from 1073741824 and increments with the existing FC ports. Similarly the index value range for the interfaces are as follows: • For GbE port the number starts from 268435456 • For Ten GbE (FCoE ports) the number starts from 402653184 • For FCIP Tunnel the number starts from 536870912 • For xFCIP Tunnel the number starts from 1342177280 • For Port channel the number starts from 671088640 • For VLAN the number starts from 1207959552 26 Fabric OS MIB Reference 53-1001339-01
