LLDP commands

dcbx version

Use dcbx version to configure the DCBX version.

Use undo dcbx version to restore the default.

Syntax

dcbx version { rev100 | rev101 | standard }

undo dcbx version

Default

The DCBX version is autonegotiated by two interfaces, with the standard version as the initial version for negotiation at the local end.

Parameters

rev100: Specifies DCBX Rev 1.00.

rev101: Specifies DCBX Rev 1.01.

standard: Specifies the IEEE Std 802.1Qaz-2011.

Usage guidelines

For DCBX to work correctly, configure the same DCBX version that is supported on both ends. As a best practice, configure the highest version supported on both ends. IEEE Std 802.1Qaz-2011, DCBX Rev 1.01, and DCBX Rev 1.00 are in descending order.

After this command is configured, an interface includes the configured DCBX version in its outgoing LLDP frames and does not negotiate the DCBX version with the peer interface.

Examples

# Configure the DCBX version as DCBX Rev 1.01 on interface Ten-GigabitEthernet1/0/1.

<HP> system-view

[HP] interface ten-gigabitethernet1/0/1

[HP-Ten-GigabitEthernet1/0/1] dcbx version rev101

display lldp local-information

Use display lldp local-information to display local LLDP information, which will be contained in the advertisable LLDP TLVs and sent to neighboring devices.

Parameters

value: Sets the TTL multiplier in the range of 2 to 10.

Usage guidelines

The TTL TLV carried in an LLDPDU determines how long the device information carried in the LLDPDU can be saved on a recipient device.

By setting the TTL multiplier, you can configure the TTL of locally sent LLDPDUs, which determines how long information about the local device can be saved on a neighboring device. The TTL is expressed by using the following formula:

TTL = Min (65535, (TTL multiplier × LLDP frame transmission interval + 1))

As the expression shows, the TTL can be up to 65535 seconds.

Examples

# Set the TTL multiplier to 6.

Default command level

network-admin

Usage guidelines

By default, when the system receives an LLDP packet, it compares the PVID value contained in the packet with the PVID configured on the receiving interface. If the two PVIDs do not match, a log message will be printed to notify the user.

You can disable PVID inconsistency check if different PVIDs are required on a link.

Examples

# Disable LLDP PVID inconsistency check.

Views

System view

Predefined user roles

network-admin

Parameters

service-bridge: Specifies the service bridge mode.

Usage guidelines

The LLDP agent types supported by LLDP depend on the LLDP bridge mode:

·     Service bridge mode—LLDP supports nearest bridge agents and nearest non-TPMR bridge agents. LLDP processes the LLDP frames with destination MAC addresses for these agents and transparently transmits the LLDP frames with other destination MAC addresses in the VLAN.

·     Customer bridge mode—LLDP supports nearest bridge agents, nearest non-TPMR bridge agents, and nearest customer bridge agents. LLDP processes the LLDP frames with destination MAC addresses for these agents and transparently transmits the LLDP frames with other destination MAC addresses in the VLAN.

The bridge mode configuration takes effect only when LLDP is enabled globally. If LLDP is disabled globally, LLDP can only operate in customer bridge mode.

Examples

# Configure LLDP to operate in service bridge mode.

Predefined user roles

network-admin

Usage guidelines

LLDP neighbor validation enables an interface to validate the identity of the neighbor based on the neighbor validation criteria configured on the interface. The neighbor validation criteria can be the chassis ID TLV, port ID TLV, or both. Each incoming LLDP packet must match all the validation criteria configured on the interface. If the neighbor information in a packet does not match the criteria, the system shuts down the data link layer and disables data transmission for the interface.

For neighbor validation to work, you must configure a minimum of one neighbor validation criterion on the interface by using the lldp neighbor-identity command.

Examples

# Enable neighbor validation on Ten-GigabitEthernet 1/0/1.

nearest-customer: Specifies nearest customer bridge agents.

nearest-nontpmr: Specifies nearest non-TPMR bridge agents.

all: Advertises all TLVs of the specified type.

·     Enables the interface to advertise the following TLVs:

¡     All basic LLDP TLVs if the all keyword is specified for basic-tlv.

¡     All IEEE 802.1 organizationally specific LLDP TLVs if the all keyword is specified for dot1-tlv.

¡     All IEEE 802.3 organizationally specific LLDP TLVs if the all keyword is specified for dot3-tlv.

·     Enables the interface to advertise all LLDP-MED TLVs except location identification TLVs if the all keyword is specified for med-tlv.

basic-tlv: Advertises basic LLDP TLVs.

management-address-tlv [ ipv6 ] [ ip-address ]: Advertises management address TLVs. The ipv6 keyword indicates that the management address to be advertised is in IPv6 format. If you do not specify this keyword, the management address in IPv4 format will be advertised. The ip-address argument specifies the management address to be advertised.

By default:

·     When you execute the lldp tlv-enable command:

¡     For a Layer 2 Ethernet or aggregate interface, the management address is the primary IPv4/IPv6 address of the VLAN interface meeting the following requirements:

-     In up state.

-     The corresponding VLAN ID is the lowest among the VLANs permitted on the port.

If you specify the ipv6 keyword, the management address is the primary IPv6 address. If you do not specify the ipv6 keyword, the management address is the primary IPv4 address.

If none of the VLAN interfaces of the permitted VLANs is assigned an IP address or all VLAN interfaces are down, the MAC address of the port will be advertised.

¡     For the management Ethernet interface, the IPv4/IPv6 address of the port will be advertised when the ip-address argument is not configured.

If you specify the ipv6 keyword, the management address is the IPv6 address. If you do not specify the ipv6 keyword, the management address is the IPv4 address.

If the port does not have an IP address, the MAC address of the port will be advertised.

·     When you execute the undo lldp tlv-enable command:

¡     If you do not specify ipv6 and ip-address, the port does not advertise any management address TLVs.

¡     If you specify ipv6 or ip-address, the port advertises the default management address TLVs.

port-description: Advertises port description TLVs.

system-capability: Advertises system capabilities TLVs.

system-description: Advertises system description TLVs.

system-name: Advertises system name TLVs.

dot1-tlv: Advertises IEEE 802.1 organizationally specific LLDP TLVs.

congestion-notification: Advertises the QCN module TLV. The QCN module supports only the nearest bridge agent.

dcbx: Advertises the DCBX TLV.

evb: Advertises the EVB module TLVs.

port-vlan-id: Advertises port VLAN ID TLVs.

protocol-vlan-id [ vlan-id ]: Advertises port and protocol VLAN ID TLVs. The vlan-id argument specifies a VLAN ID in the TLVs to be advertised. The VLAN ID is in the range of 1 to 4094, and the default is the lowest VLAN ID on the port.

vlan-name [ vlan-id ]: Advertises VLAN name TLVs. The vlan-id argument specifies a VLAN ID in the TLVs to be advertised. The VLAN ID is in the range of 1 to 4094, and the default is the lowest VLAN ID on the port.

management-vid [ mvlan-id ]: Advertises the management VLAN ID TLV. The mvlan-id argument specifies a management VLAN ID in the TLVs to be advertised. The management VLAN ID is in the range of 1 to 4094. If no management VLAN ID is specified, the value 0 is advertised, which means that the LLDP agent is not configured with a management VLAN ID.

dot3-tlv: Advertises IEEE 802.3 organizationally specific LLDP TLVs.

link-aggregation: Advertises link aggregation TLVs.

mac-physic: Advertises MAC/PHY configuration/status TLVs.

max-frame-size: Advertises maximum frame size TLVs.

power: Advertises power in MDI TLVs and power stateful control TLVs.

med-tlv: Advertises LLDP-MED TLVs.

location-id: Advertises location identification TLVs.

civic-address: Inserts the typical address information about the network device in location identification TLVs .

device-type: Sets a device type value in the range of 0 to 2:

·     Value 0 specifies a DHCP server.

·     Value 1 specifies a switch.

·     Value 2 specifies an LLDP-MED endpoint.

country-code: Sets a country code defined in ISO 3166.

{ ca-type ca-value }&<1-10>: Configures address information. ca-type represents the address information type in the range of 0 to 255. ca-value represents address information, a string of 1 to 250 characters. &<1-10> indicates that you can specify up to 10 ca-type ca-value pairs.

elin-address: Inserts telephone numbers for emergencies in location identification TLVs.

tel-number: Sets the telephone number for emergencies, a string of 10 to 25 characters.

network-policy [ vlan-id ]: Advertises network policy TLVs. The vlan-id argument specifies the voice VLAN ID sent to voice terminals, in the range of 1 to 4094. If you do not specify this argument, the command advertises information about the VLAN assigned by the authentication server or the voice VLAN ID configured on the interface. For more information, see "Configuring VLANs."

power-over-ethernet: Advertises extended power-via-MDI TLVs.

Usage guidelines

Nearest bridge agents are not supported on aggregate interfaces.

You can enable the device to advertise multiple types of TLVs by using this command without the all keyword specified.

If the MAC/PHY configuration/status TLV is not advertisable, none of the LLDP-MED TLVs will be advertised whether they are advertisable. If the LLDP-MED capabilities TLV is not advertisable, the other LLDP-MED TLVs will not be advertised regardless of whether they are advertisable.

The port and protocol VLAN ID TLV, VLAN name TLV, and management VLAN ID TLV in IEEE 802.1 organizationally specific LLDP TLVs can be configured only for nearest bridge agents. The configuration can be inherited by nearest customer bridge agents and nearest non-TPMR bridge agents.
