Interfaces Group 2 Interfaces Group Implementation of the Interfaces group is mandatory for all systems. ifNumber 1.3.6.1.2.1.2.1 The number of network interfaces present on this system, regardless of their current state. The return value is 5 for the SilkWorm 12000, 24000, and 48000 (single domain), 7 for the SilkWorm 12000 and 24000 (dual-domain). All non-bladed systems will have a value of 3. 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. The number of entries inside the SilkWorm 12000, 24000, and 48000 directors is 1 to 3 for FCIP; otherwise, the value is 1 or 2. ifDescr 1.3.6.1.2.1.2.2.1.2 A textual string containing information about the interface. The ifDescr for non-bladed switches includes: lo, eth0, and fc0. The ifDescr for SilkWorm 12000, 24000, and 48000 directors includes: lo, eth0, and fc0, as well as fc1, eth0:1, and eth0:2. ifType 1.3.6.1.2.1.2.2.1.3 The type of interface, designated by the physical/link protocol(s) immediately below the network layer in the protocol stack.
