Configuration Examples for the Device Sensor Feature
The following example shows how to create a CDP filter containing a list of TLVs:
Switch> enable
Switch# configure terminal
Switch(config)# device-sensor filter-list cdp list cdp-list
Switch(config-sensor-cdplist)# tlv name address-type
Switch(config-sensor-cdplist)# tlv name device-name
Switch(config-sensor-cdplist)# tlv number 34
Switch(config-sensor-cdplist)# end
The following example shows how to create an LLDP filter containing a list of TLVs:
Switch> enable
Switch# configure terminal
Switch(config)# device-sensor filter-list lldp list lldp-list
Switch(config-sensor-lldplist)# tlv name chassis-id
Switch(config-sensor-lldplist)# tlv name management-address
Switch(config-sensor-lldplist)# tlv number 28
Switch(config-sensor-lldplist)# end
The following example shows how to create a DHCP filter containing a list of options:
Switch> enable
Switch# configure terminal
Switch(config)# device-sensor filter-list dhcp list dhcp-list
Switch(config)# device-sensor filter-list dhcp list dhcp-list
Switch(config-sensor-dhcplist)# option name domain-name
Switch(config-sensor-dhcplist)# option name host-name
Switch(config-sensor-dhcplist)# option number 50
Switch(config-sensor-dhcplist)# end

Only CDP, LLDP, and DHCP protocols are supported.
The session limit for profiling ports is 32.
The length of one TLV must not be more than 1024 and the total length of TLVs (combined length
of TLVs) of all protocols must not be more than 4096.
Device Sensor profiles devices that are only one hop away.
