sysServices

INTEGER{(0,127)}

read-only

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.

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