Default
No IEEE 802.1 Organizationally Specific TLV is selected.
Command Mode
Interface configuration
Usage Guideline
If the optional TLVs advertisement state is enabled, they will be encapsulated in
LLDPDU and sent to other devices.
The Protocol Identify TLV optional data type indicates whether the corresponding
Local System's Protocol Identify instance will be transmitted on the port. The
Protocol Identify TLV provides a way for stations to advertise protocols that are
important to the operation of the network. Such as Spanning Tree Protocol, the
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 function and advertising protocol identify are enabled
on a port, the Protocol Identify TLV will be advertised.
Only when the configured VLAN-ID matches the configuration of 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:
The following example disables advertising Port VLAN ID TLV:
This example shows how to enable advertising Port And Protocol VLAN ID TLV,
the advertised VLAN includes 1 to 3.
protocol-identify
[
PROTOCOL-NAME
]
Specify the Protocol Identify TLV to send. The Protocol Identify 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 no form of the command.
