protocol-identity
[PROTOCOL-NAME]
Default
No IEEE 802.1 Organizationally Specific TLV is selected.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is available for physical port configurations. If the optional TLVs advertisement state is
enabled, they will be encapsulated in LLDPDUs and sent to other devices.
The protocol identity TLV optional data type indicates whether to advertise the corresponding local
system's protocol identity instance on the port. The protocol identity TLV provides a way for devices to
advertise protocols that are important to the operation of the network. For example, protocols like
Spanning Tree Protocol, Link Aggregation Control Protocol, and numerous vendor proprietary
variations are responsible for maintaining the topology and connectivity of the network. When both of
the protocol functions are working and the protocol identity is enabled for advertising on a port, the
protocol identity TLV will be advertised.
Only when the configured VLAN ID matches the configuration of the protocol VLAN on that interface
and the VLAN exists, then the PPVID TLV for that VLAN will be sent. Only when the interface is a
member port of the configured VLAN ID, the VLAN will be advertised in VLAN Name TLV.
Example
This example shows how to enable advertising Port VLAN ID TLV.
Switch# configure terminal
Switch(config)# interface eth 1/0/1
Switch(config-if)# lldp dot1-tlv-select port-vlan
Switch(config-if)#
This example shows how to enable the VLAN Name TLV advertisement from vlan1 to vlan3.
Switch# configure terminal
Switch(config)#interface eth 1/0/1
Switch(config-if)#lldp dot1-tlv-select vlan-name 1-3
Switch(config-if)#
This example shows how to enable the LACP Protocol Identity TLV advertisement.

ID is specified, all applicable VLANs will be sent. In the no form of this
command, if no VLAN ID is specified, all configured VLANs for the
VLAN name TLV will be cleared and no VLAN name TLV will be sent.
Specifies the Protocol Identity TLV to send. The Protocol Identity TLV
is an optional TLV that allows an IEEE 802 LAN station to advertise
particular protocols that are accessible through the port.
The valid strings for PROTOCOL-NAME are:
eapol: Extensible Authentication Protocol (EAP) over LAN
lacp: Link Aggregation Control Protocol
gvrp: GARP VLAN Registration Protocol
stp: Spanning Tree Protocol
The protocol name is optional. When no specific protocol string is
specified, all protocols are selected or de-selected in the no form of
the command.
