To have your device work with Cisco IP phones, you must enable CDP-compatible LLDP globally and 

then configure CDP-compatible LLDP to work in TxRx mode on the specified port(s).  

# Configure CDP-compatible LLDP to operate in TxRx mode on GigabitEthernet 2/0/1.  

<Sysname> system-view 

[Sysname] interface gigabitethernet 2/0/1 

[Sysname-GigabitEthernet2/0/1] lldp compliance admin-status cdp txrx 

undo lldp compliance cdp

Use the lldp compliance cdp command to enable global CDP compatibility.  

Use the undo lldp compliance cdp command to restore the default.  

By default, global CDP compatibility is disabled.  

Note that, as the maximum TTL allowed by CDP is 255 seconds, your TTL configuration, that is, the 

product of the TTL multiplier and the LLDPDU transmit interval, must be no more than 255 seconds for 

CDP-compatible LLDP to work properly with Cisco IP phones. 

Related commands: lldp hold-multiplier, lldp timer tx-interval.
