42 MIB-II (RFC1213-MIB)
sysServices
OID 1.3.6.1.2.1.1.7
Description 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
(2
3-1
). In contrast, a node that is a host and offers application services has a value of 72
(2
4-1
+ 2
7-1
). Note that 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)
Note 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.
ifNumber
OID 1.3.6.1.2.1.2.1
Description The number of network interfaces (regardless of their current state) present on this system.
Note The return value is 5 for the SAN Director 2/128 and 4/256 SAN Director (single
domain), 7 for the Core Switch 2/64 or the SAN Director 2/128 (dual-domain). All
non-bladed systems will have a value of 3.
Interfaces table
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.
ifTable
OID 1.3.6.1.2.1.2.2
Description A list of interface entries. The number of entries is given by the value of ifNumber.
ifEntry
OID 1.3.6.1.2.1.2.2.1
Description An interface entry containing objects at the subnetwork layer and below, for a particular
interface.
