Usage Guidelines Use the device-sensor filter-spec command to specify a list of CDP or LLDP TLV fields or DHCP
options to be included in Device Sensor outputs.
Certain TLVs and message types such as DISCOVER, OFFER, REQUEST, ACK, and IP address are
unconditionally excluded. These excluded TLVs and message types are used as transport for higher layer
protocols, which change frequently and convey little useful information about endpoints. OFFER
messages are also excluded because they can be received from multiple servers, and therefore, do not
convey useful endpoint data.
Examples
The following example shows how to apply a CDP TLV filter list to the Device Sensor output:
Switch> enable
Switch# configure terminal
Switch(config)# device-sensor filter-spec cdp include cdp-list1
OL-27596 -01
device-sensor filter-spec {cdp | lldp | dhcp} {exclude {all | list list-name} | include list list-name}
Applies a CDP TLV filter list to the device sensor output.
Applies a LLDP TLV filter list to the device sensor output.
Applies a DHCP options filter list to the device sensor output.
Specifies the protocol TLVs or DHCP options to be excluded from the device sensor
output.
Disables all notifications for the associated protocol.
Specified the name of the filter list.
Specifies the TLVs or DHCP options that should be included in the Device Sensor
