Configuring Device Sensor
Applying a Protocol Filter to the Device Sensor Output
Beginning in privileged EXEC mode, follow these steps to apply a CDP, LLDP, or DHCP filter to the sensor output. The output
is session notifications to internal sensor clients and accounting requests to the RADIUS server.
Note
Only one filter list can be included or excluded at a time.
Tracking TLV Changes
By default, client notifications and accounting events are generated only when an incoming packet includes a TLV that has not
previously been received within a given session.
To enable client notifications and accounting events for TLV changes, follow these steps, beginning in privileged EXCEC
mode:
Step 3

}
Switch(config-sensor-dhcplist)# option
number 50
Adds individual DHCP options to the option list. You can delete the
entire option list without removing options individually from the list
by using the
no device-sensor filter-list dhcp list option-list-name
command.

Switch(config)# end
Returns to privileged EXEC mode.
