sysServices

Type INTEGER

Access R

Description A value which indicates the set of services that this entity primarily

offers. The value is a sum. This sum initially takes the value zero,

then, for each layer, L, in the range 1 through 7, that this node

performs transactions for, 2 raised to (L - 1) is added to the sum. For

example, a node which performs primarily routing functions would

have a value of 4 (2^(3-1)). In contrast, a node which is a host offering

application services would have 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 (e.g., repeaters)

2 datalink/subnetwork (e.g., bridges)

3 internet (e.g., IP gateways)

4 end-to-end (e.g., IP hosts)

7 applications (e.g., mail relays)

For systems including OSI protocols, layers 5 and 6 may also be

counted.

Interfaces Group

ifNumber

Type INTEGER

Access R

Description The number of network interfaces (regardless of their current state)

present on this system.
