sysServices

INTEGER{(0,127)}

read-only

A value which indicates the set of services that this

entity may potentially offer. 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 only

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., supports the IP)

4 end-to-end (e.g., supports the TCP)

7 applications (e.g., supports the SMTP)

For systems including OSI protocols, layers 5 and 6

may also be counted.

This object is implemented as defined in the corresponding MIB files.
