Troubleshooting Commands
The following commands can help troubleshoot Device Sensor.
• debug device-sensor {errors | events}
• debug authentication all
Restrictions for Device Sensor
• 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.
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
