Default level

2: System level

Parameters

disable: Specifies the disable mode, where CDP-compatible LLDP cannot receive or transmit CDP packets.

txrx: Specifies the TxRx mode, where CDP-compatible LLDP can send and receive CDP packets.

Description

Use the lldp compliance admin-status cdp command to configure the operating mode of CDP-compatible LLDP on a port or port group.

By default, CDP-compatible LLDP operates in disable mode.

For your device to work with Cisco IP phones, you must enable CDP-compatible LLDP globally and then configure CDP-compatible LLDP to operate in TxRx mode on the specified ports.

Related commands: lldp compliance cdp.

Examples

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

<Sysname> system-view

Default level

2: System level

Parameters

None

Description

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

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

By default, CDP compatibility is globally disabled.

Because the maximum TTL allowed by CDP is 255 seconds, the TTL configuration must be no more than 255 seconds for CDP-compatible LLDP to operate with Cisco IP phones. The TTL configuration is the product of the TTL multiplier and the LLDPDU transmit interval.

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

Parameters

None

Description

Use the lldp enable command to enable LLDP.

Use the undo lldp enable command to disable LLDP.

By default, LLDP is enabled globally and on all ports.

LLDP takes effect on a port only when LLDP is enabled both globally and on the port.

Examples

# Disable LLDP on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

Use the lldp management-address-tlv command to enable management address advertising and set the management address.

Use the undo lldp management-address-tlv command to disable management address advertising in LLDPDUs.

By default, the management address is advertised through LLDPDUs. For an Ethernet port, the management address is the main IP address of the lowest-ID VLAN carried on the port. If none of the carried VLANs is assigned an IP address, no management address will be advertised.

An LLDPDU carries only one management address TLV. If you set the management address repeatedly, the latest one takes effect.

In Ethernet interface view, if you run the lldp management-address-tlv command without specifying the ip-address argument, the advertised management address is the main IP address of the lowest-ID VLAN carried on the interface. If none of the carried VLANs is assigned an IP address, no management address will be advertised.

# Set the management address to 192.6.0.1 for GigabitEthernet 1/0/1.

Parameters

all: Advertises all basic LLDP TLVs, IEEE 802.1 organizationally specific LLDP TLVs, or IEEE 802.3 organizationally specific LLDP TLVs when the all keyword is specified for basic-tlv, dot1-tlv, or dot3-tlv; advertises all LLDP-MED TLVs except location identification TLVs when the all keyword is specified for med-tlv.

By default, the device can advertise all types of LLDP TLVs, except DCBX TLVs and location identification TLVs.

To enable the device to advertise LLDP-MED TLVs, you must first enable it to advertise LLDP-MED capabilities TLVs.

To disable the device from advertising LLDP-MED capabilities TLVs, you must first disable it from advertising other LLDP-MED TLVs.

To disable the device from advertising MAC/PHY configuration/status TLVs, you must first disable it from advertising LLDP-MED capabilities TLVs.

If you enable the device to advertise LLDP-MED capabilities TLVs, you also enable it to advertise MAC/PHY configuration/status TLVs.

To enable the device to advertise multiple types of TLVs, you can execute the lldp tlv-enable command repeatedly without the all keyword specified.
