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:
Command Purpose
Step 1
configure terminal
Switch# configure terminal
Enters global configuration mode.
Step 2
device-sensor filter-spec {cdp | dhcp
| lldp} {exclude {all | list
list-name} | include list list-name}
Switch(config)# device-sensor
filter-spec cdp include list list1
Applies a specific protocol filter containing a list of protocol TLV
fields or DHCP options to the Device Sensor output.
• cdp--Applies a CDP TLV filter list to the device sensor output.
• lldp--Applies an LLDP TLV filter list to the device sensor output.
• dhcp--Applies a DHCP option filter list to the device sensor
output.
• exclude--Specifies the TLVs that must be excluded from the
device sensor output.
• include--Specifies the TLVs that must be included from the
device sensor output.
• all--Disables all notifications for the associated protocol.
• list list-name--Specifies the protocol TLV filter list name.
Step 3
end
Switch(config)# end
Returns to privileged EXEC mode.
Command Purpose
Step 1
configure terminal
Switch# configure terminal
Enters global configuration mode.
Step 2
device-sensor notify all-changes
Switch(config)# device-sensor notify
all-changes
Enables client notifications and accounting events for all TLV
changes, that is, where either a new TLV is received or a previously
received TLV is received with a new value in the context of a given
session.
Note Use the default device-sensor notify or the device-sensor notify
new-tlvs command to return to the default TLV.
Step 3
end
Switch(config)# end
Returns to privileged EXEC mode.
