2 Interfaces group TABLE 8 Object and OID sysLocation 1.3.6.1.2.1.1.6 sysServices 1.3.6.1.2.1.1.7 Access Read-write Read only Description The physical location of this node (for example, telephone closet, 3rd floor). The minimum length of the string must be four. The default is End User Premise. Set this value using the snmpconfig command. A value that indicates the set of services that this entity primarily offers. The value is a sum. This sum initially takes the value 0. Then, for each layer, L, in the range 1 through 7, for which this node performs transactions, 2 raised to (L - 1) is added to the sum. For example, a node that primarily performs routing functions has a value of 4 (23-1). In contrast, a node that is a host and offers application services has a value of 72 (24-1 + 27-1). In the context of the Internet suite of protocols, values should be calculated accordingly: Layer functionality • 1 = physical (for example, repeaters) • 2 = datalink/subnetwork (for example, bridges) • 3 = internet (for example, IP gateways) • 4 = end-to-end (for example, IP hosts) • 7 = applications (for example, mail relays) For systems including OSI protocols, layers 5 and 6 also can be counted. The return value is always 79. Interfaces group Implementation of the Interfaces group is mandatory for all systems. FCIP tunnel support is added in Fabric OS 5.3.0 and later. 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. TABLE 9 Object and OID Access Description ifNumber 1.3.6.1.2.1.2.1 ifTable 1.3.6.1.2.1.2.2 ifEntry 1.3.6.1.2.1.2.2.1 Read only 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. Not accessible 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. Not An interface entry containing objects at the subnetwork layer and below, for a accessible particular interface. 34 Fabric OS MIB Reference 53-1002750-01
