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 initially set to 0. For each layer L in the range 1 through 7 for which
this node performs transactions, 2 raised to the power (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 1 Physical, such as repeaters
Layer 2 Datalink/subnetwork, such as bridges
Layer 3 Internet, such as IP gateways
Layer 4 End-to-end, such as IP hosts
Layer 5 Session (OSI only)
Layer 6 Presentation (OSI only)
Layer 7 Applications, such as mail relays
Note For systems including OSI protocols, Layers 5 and 6 might also be counted. The return
value is always 72.
