8 LLDP configuration and management

Enabling and disabling the receiving and transmitting of LLDP frames

By default both transmit and receive for LLDP frames is enabled. To enable or disable the receiving (rx) and transmitting (tx) of LLDP frames, perform the following steps from Privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter the mode command to:

•Enable only receiving of LLDP frames:

switch(conf-lldp)#mode rx

•Enable only transmitting of LLDP frames:

switch(conf-lldp)#mode tx

•Disable all LLDP frame transmissions

switch(conf-lldp)#mode no mode

Configuring the transmit frequency of LLDP frames

To configure the transmit frequency of LLDP frames, perform the following steps from Privileged EXEC mode.The default is 30 seconds.

1.Enter the configure terminal command to access global configuration mode.

2.Enter LLDP configuration mode.

switch(config)#protocol lldp

3. Configure the transmit frequency of LLDP frames.

switch(conf-lldp)#hello 45

Configuring the hold time for receiving devices

To configure the hold time for receiving devices, perform the following steps from Privileged EXEC mode. This configures the number of consecutive LLDP hello packets that can be missed before declaring the neighbor information as invalid. The default is 4.

1.Enter the configure terminal command to access global configuration mode.

2.Enter LLDP configuration mode.

switch(config)#protocol lldp

3. Configure the hold time for receiving devices.

switch(conf-lldp)#multiplier 6

Advertising the optional LLDP TLVs

NOTE

If the advertise optional-tlvcommand is entered without keywords, all optional LLDP TLVs are advertised.

To advertise the optional LLDP TLVs, perform the following steps from Privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter LLDP configuration mode.

switch(config)#protocol lldp
