40CHAPTER 4: GROUPING NETWORK DEVICES IN THE MAP
Attributes | To understand how Traffix Manager groups devices in the Map, it helps to |
| be familiar with the concepts of attributes and groupings. |
| An attribute is a label for a piece of information about a device: for |
| example, location or IP address. Traffix Manager has a number of |
| predefined attributes; you can change these or add your own. |
| At any one time, each attribute of a particular device is either currently |
| unassigned (not defined), or has a single value. For example, the value of |
| the location of a device might be Boston, or the location might be |
| unknown, or unassigned. |
Predefined Attributes There are a number of predefined attributes in Traffix Manager that you can use to create your own groupings. For these predefined attributes, values are usually assigned automatically as each device is discovered.
You cannot delete a predefined attribute, or change its name.
Table 5 Predefined Attributes
Name | Description |
|
|
Name | DNS Name or Network Layer address. |
NL Type | Network Layer protocol. |
NL Addr | Network Layer (IP) address. |
Network | |
| generated from the Network Layer |
| address. |
Subnet | This attribute is set to SubnetsDB if |
| the object matches an entry in the |
| SubnetsDB file. Otherwise it is |
| unassigned. See Appendix D, “Using |
| the SubnetsDB File”. |
Discovery Time | Time (in seconds, since January 1st |
| 1970) when Traffix Manager |
| discovered device. |
Last Activity Time | Time (in seconds, since January 1st |
| 1970) when the device last sent or |
| received traffic. |
Type | Device/Aggregated/DHCP Device. |
