132APPENDIX C: AGGREGATING DEVICES

If layer 2 above the name is selected, the device office.acme.com is aggregated into the device representing

.com.

If a network device does not have the selected layer above the name, then the device is aggregated into a device representing the highest DNS layer possible. office.acme.com does not have a layer three above its name and would therefore be aggregated into the device representing the DNS layer .com.

■Aggregate from tail allows you to specify a DNS layer above the end of the device name. A network device that has a non-local DNS domain is aggregated into a Traffix Manager device representing this DNS layer.

For example, if DNS layer 2 is selected, the device mydevice.acme.com is aggregated into the device representing the DNS domain acme.com.

■Discard Any network device that has a non-local DNS domain is discarded immediately, and no data for that device is collected.

Setting a Maximum Device Limit

You can specify a device limit of 100,000 devices. This allows you to monitor local devices in detail, but reduce the detail of data kept about non-local devices. This setting is treated as a “hint” by Traffix Manager: if new local devices are seen after this user-defined limit is reached, the setting is increased gradually, up to the maximum version limit, to allow for the new local devices to be stored.

This prevents unnecessary loss of information about local devices.
