3.2.2
“sysObjectID” Object (system 2)
This object provides the authoritative identification of the network management subsystem 
contained in the unit. This object will be set to display the following object identifier:
sme-chassis-8820[Company Enterprise OID].1.14.9.14.5.1
sme-chassis-8620[Company Enterprise OID].1.14.9.14.5.2
3.2.3
“sysUpTime” Object (system 3)
The time (in hundredths of a second) since the network management portion of the system 
was last reinitialized.
3.2.4
“sysContact” Object (system 4)
The textual identification of the contact person for this managed node, together with 
information on how to contact this person.  If no contact information is known, the value is 
the zero-length string.
3.2.5
“sysName” Object (system 5)
An administratively-assigned name for this managed node. By convention, this is the 
node’s fully-qualified domain name.  If the name is unknown, the value is the zero-length 
string.
3.2.6
“sysLocation” Object (system 6)
The physical location of this node (for example, ‘telephone closet, 3rd floor’).  If the 
location is unknown, the value is the zero-length string.
3.2.7
“sysServices” Object (system 7).
This object provides a value which indicates the set of services that are potentially offered 
by the DSL unit. The value is a sum. This sum initially takes the value zero. Then, for each 
layer L in the range of 1-7 (for 7 OSI layers) that this node performs transactions for, 
2 raised to L-1 is added to the sum. For example, a node performing only routing functions 
would have a value of 4(z^(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. For systems including OSI 
protocols, layers 5 and 6 may also be counted. 
The following table shows the values supported :
