LLDP commands -- cdp voice-vlan

Use cdp voice-vlan to set the voice VLAN ID carried in CDP frames.

Use undo cdp voice-vlan to restore the default.

Syntax

cdp voice-vlan vlan-id

undo cdp voice-vlan

Default

No voice VLAN ID is configured to be carried in CDP frames.

Views

Layer 2 Ethernet interface view

Default command level

network-admin

mdc-admin

Parameters

vlan-id: Specifies a voice VLAN ID to be advertised, in the range of 1 to 4094.

Usage guidelines

With this command configured, CDP frames sent to IP phones from the interface carry the voice VLAN ID specified in this command. IP phones use the voice VLAN ID to send voice traffic.

Examples

# Set the voice VLAN ID carried in CDP frames to 100.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] cdp voice-vlan 100

LLDP commands -- dcbx version

Use dcbx version to set 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 not configured. It is autonegotiated by the local port and peer port.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

mdc-admin

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, set the same DCBX version on the local port and peer port. As a best practice, set 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 the configuration, LLDP frames sent by the local port carry information about the configured DCBX version. The local port and peer port do not negotiate the DCBX version.

When the DCBX version is autonegotiated, the version IEEE Std 802.1Qaz-2011 is preferentially negotiated.

Examples

# Set the DCBX version to Rev. 1.01 on interface GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] dcbx version rev101

Parameters

agent: Specifies an LLDP agent type. If you do not specify an agent type, this command applies to the nearest bridge agent.

· nearest-customer: Specifies the nearest customer bridge agent.

· nearest-nontpmr: Specifies the nearest non-TPMR bridge agent.

ipv6: Specifies an IPv6 management address. If you do not specify this keyword, an IPv4 management address will be advertised.

ip-address: Specifies the management address to be advertised.

interface loopback interface-number: Specifies a loopback interface by its number in the range of 0 to 127. The IP address of the loopback interface will be advertised as the management address. The value range for the interface-number argument varies by device model.

interface vlan-interface interface-number: Specifies a VLAN interface by is number in the range of 1 to 4094. The IP address of the VLAN interface will be advertised as the management address.

Usage guidelines

If you execute this command multiple times, the most recent configuration takes effect.

You can configure advertisement of the management address TLV globally or on a per-interface basis. The device selects the management address TLV advertisement setting for an interface in the following order:

1. Interface-based setting, configured by using the lldp tlv-enable command with the management-address-tlv keyword.

2. Global setting, configured by using the lldp global tlv-enable basic-tlv management-address-tlv command.

3. Default setting for the interface.

By default:

?span style='font:7.0pt "Times New Roman"'> The nearest bridge agent and nearest customer bridge agent advertise the management address TLV.

?span style='font:7.0pt "Times New Roman"'> The nearest non-TPMR bridge agent does not advertise the management address TLV.

The IPv4 or IPv6 address of the LLDP frame sending port will be advertised as the management address when the following conditions exist:

· The ip-address argument is not configured.

· The specified loopback or VLAN interface does not have an IPv4 or IPv6 address, or the specified interface does not exist.

If the LLDP frame sending port does not have an IPv4 or IPv6 address, the MAC address of the port will be advertised.

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.

Examples

# Enable advertisement of the management address TLV globally and set the advertised management address to 192.168.1.1.

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 set the TTL of locally sent LLDP frames. 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.

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 a 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 a 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.

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.

Parameters

agent: Specifies an LLDP agent type. If you do not specify an agent type in Ethernet or management Ethernet interface view, the command configures the types of advertisable TLVs for nearest bridge agents.

nearest-customer: Specifies nearest customer bridge agents.

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

all: Advertises all TLVs of the specified type. This keyword enables the interface to advertise 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.

· 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 | interface loopback interface-number ]: 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 s pecifies the management address to be advertised. The interface loopback interface-number option specifies the management address as the IP address of a loopback interface specified by its number. By default, the following rules apply:

· When you execute the lldp tlv-enable command:

?span style='font:7.0pt "Times New Roman"'> For a Layer 2 Ethernet or aggregate interface, the management address is the IPv4 or IPv6 address of the VLAN interface that meets 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 IPv6 address. If you do not specify the ipv6 keyword, the management address is the IPv4 address.

If none of the VLAN interfaces of the permitted VLANs is assigned an IPv4 or IPv6 address or all VLAN interfaces are down, the MAC address of the port will be advertised.

?span style='font:7.0pt "Times New Roman"'> For a Layer 3 Ethernet interface, the IPv4 or IPv6 address of the port will be advertised when the following conditions exist:

- The ip-address argument is not configured.

- The specified loopback interface does not have an IPv4 or IPv6 address, or the specified loopback interface does not exist.

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 IPv4 or IPv6 address, the MAC address of the port will be advertised.

?span style='font:7.0pt "Times New Roman"'> For a synchronous/asynchronous serial interface, standard POS interface, POS channel interface, Layer 3 aggregate interface, or management Ethernet interface, the IPv4 or 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 IPv4 or IPv6 address, the MAC address of the port will be advertised.

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

?span style='font:7.0pt "Times New Roman"'> For a Layer 2/Layer 3 Ethernet interface, management Ethernet interface, or Layer 2/Layer 3 aggregate interface:

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

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

?span style='font:7.0pt "Times New Roman"'> For a synchronous/asynchronous serial interface, standard POS interface, or POS channel interface:

- 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 QCN TLVs. Only the nearest bridge LLDP interfaces can advertise QCN TLVs.

dcbx: Advertises the DCBX TLVs.

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. If you do not specify a VLAN ID and the port is not assigned to any VLAN, the PVID of the port is advertised.

management-vid [ mvlan-id ]: Advertises management VLAN ID TLVs. The m vlan-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 you do not specify this option, 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.

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 network device.

· 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 to be advertised, in the range of 1 to 4094.

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 or not they are advertisable. If the LLDP-MED capabilities TLV is not advertisable, the other LLDP-MED TLVs will not be advertised regardless of whether or not they are advertisable.

The port and protocol VLAN ID, VLAN name, and management VLAN ID TLVs 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.

Examples

# Enable the nearest customer bridge agents on GigabitEthernet 1/0/1 to advertise link aggregation TLVs of the IEEE 802.1 organizationally specific TLVs.
